Dream a little!  Imagine a world in the year 2065 where society has successfully made a switch to sustainable living.  What would a sustainable city look like?  How about a sustainable small town?  A self-sustaining Mars colony?  Describe some details/specific features you would expect to see.  You can assume that technology has made major developments that can be extrapolated from today, but we will not consider major disruptive changes such as [https://en.wikipedia.org/wiki/Technological_singularity the Singularity] which are hard to predict & assess.  I recommend completing [[Chem321:Unit_14|Unit 14]] before posting.

* There are many advances in green technology in efforts to reduce the non-renewable resources we use as well as the carbon emissions we give off by current practices. By 2050 I would like to see many homes, as well as business' and factories producing their own energy. Throughout the semester I learned about the benefits of solar panels and wind turbines. We would see many roofs in the future with solar panels. These places would be using that energy for lighting, cooking, and heating, just to name a few. In addition to solar panels on the roof, we would see an increase of small scale and large scale wind turbines (depending on where they are being used). This too would be used for producing electricity. Both methods can drastically reduce the need to burn fossil fuels, and help us move away from using non-renewable resources. In the future these methods will become more affordable, and it will be the common method in obtaining energy for use.

* Angela, your proposal for rooftop solar panels and wind turbines competes with my proposal for rooftop greenhouses. As a rebuttal to your suggestion - I'd like to argue that wind-farms are better placed in environments where wind is abundant. This may suggest that wind energy could be more efficiently, in cost as well as time, be produced in strategically chosen sites. In contrast - rooftop greenhouses would allow for farmers to create controlled growth environments for their crops in any location,  which could be grown through hydroponic methods. These crops could then be distributed locally to the population of the city. Furthermore, the reading assigned to us written by Chris Goodall suggests that solar energy thus far has not been able to replicate the cost-efficiency of simply insulating buildings more effectively. This is likely a greater concern in cities far from the equator where light might not be as abundant as it is in other cities. If solar energy is to become more cost effective though - perhaps you and I could compromise and find a way to created greenhouses that control internal heat alongside the use of solar panels found on the tops of the greenhouses.

*Tom, i really like the idea of rooftop greenhouses, but i find it hard to believe that in a near future most rooftops will be producing their own food. It is a great idea for farmers as you have mentioned, but i do not think the average "joe" will have time to maintain their garden, especially as we continue to live faster pace lives and demand things quicker. I believe that price is a large factor in why solar panels have not taken off, but with time and increased research they should become more obtainable. As for your comment on those who may not have as much wind for wind turbines or sun for solar panels to be effective, i agree these are issues for usage in those areas. The fact is most areas get sun and wind, and getting those areas to switch to solar panels or turbines would be the first step in decreasing our emissions and pollution.[[User:Angela.M.Caracci|Angela.M.Caracci]] ([[User talk:Angela.M.Caracci|talk]]) 22:58, 7 August 2013 (EDT)
 
  
::*I think this is an excellent idea, often called "distributed generation," and although it's only marginally cost-effective now (it is viable with subsidies) it will be much more viable by 2050.  One of the problems with things like the hydrogen economy is the high cost of transporting the fuel around (I once read an academic article that said that this issue would mean that hydrogen would never be a viable fuel.)  Even with other renewable energy sources like wind, often the best locations (e.g., North Dakota in the US) are far from centers of population (east & west coasts), so the electricity often needs to go long distances.  Although a solar panel in NYC makes much less electricity than one in the near-deserts of Texas (or near you in Nevada!), it is producing power right where it's needed, so you don't have the power losses (about 1% per 100 miles) and costs associated with long power lines.  You are also more self-sufficient in the event of ice storms, etc.  I can see the issue of competition with Tom's rooftops proposals, but I suspect your idea might work best in rural areas (where energy supply may be more expensive & unreliable, but local food is cheaply available) whereas Tom's would be most effective in the city.  I'm personally a big fan of anything that can work in a more decentralized way.  Naturally you still need SOME wind or sun, and not every location would work, but I think this will play a significant role by 2050.

* A viable green technology I would like to see widely adopted by 2050 is commercial scale rooftop produce production. I have seen pictures of this sort of thing in optimistic “green” depictions of future cities. A company, called Lufa Farms, has successfully begun turning profits using a rooftop greenhouse in Montreal, Canada, a fairly cold environment. Lufa Farms describes using CO2 emissions from fuels used in energy production – to help the plants in the greenhouse grow – which allows for the farm to be close to carbon neutral (source - http://www.smartplanet.com/blog/intelligent-energy/coming-soon-commercial-scale-rooftop-produce/16889). Additionally – the greenhouse provides insulation for the buildings below it as it utilizes heat from the building to maintain adequate temperatures for growth in the greenhouse. These city rooftop greenhouses could provide food for entire cities through conservative methods such as hydroponics – thus reducing costs, oil use, use of raw materials, and emissions associated with transport of produce. Furthermore – these rooftop greenhouses could even potentially contain aquaponic systems! In this way – not only could rooftop greenhouses provide vegetables cities locally, but these greenhouses could also provide animal protein for the city population! Of course – a balance such as this would be quite the challenge to make profitable with the very limited space available. Additionally – the prospect of actually providing produce for an entire city utilizing these rooftop greenhouses is rather slim. The Food and Agriculture Organization estimates the need for 0.5 hectares (1.2 acres) of land necessary for the growth of produce for a single American resident in a year – however this estimate includes the current levels of meat consumption. If per capita meat consumption is to be reduced, then the use of rooftop greenhouses could potentially ACTUALLY provide a majority of the dietary needs of a community. On top of these great things – if rooftop buildings became commonplace in largely populated cities such as Tokyo or NYC, then the amount of soil turned and utilized for agriculture could potentially be re-allocated for the production of bio-fuels! These biofuels could then in turn be used to run our cars, buildings, and greenhouses. This use of biofuels could then subsequently vastly reduce carbon emissions used by a city.

*I think commercial scale produce production is a great viable idea. There is so much area on these rooftops, especially in cities where much light doesn't reach the ground that it can be utilized to grow produce. Even if the growth was on a small scale or private based operation then people could benefit from this tremendously. Think about a house in NYC with several tenants that could grow their own produce for themselves. With all these people chipping in they could grow a lot of food for a rather cheap price.

*Tom, I love the idea of commercial scale rooftop produce production. Cities are always looked at as "concrete jungles" but I like the thought of looking up at a rooftop and seeing something that resembles a real jungle with edible produce. I also think that this could be easily done by 2050, and it makes me wonder why this hasn't been done on a large scale already.  [[User:KatieLaVoie|KatieLaVoie]] ([[User talk:KatieLaVoie|talk]]) 09:03, 9 August 2013 (EDT)

I would really like to see biodiesel that replaces fossil fuels we use in our cars be widely adopted by 2050. Biodiesel comes from a process that turns old cooking oil into a Constable form of fuel for diesel engines. This alternative would look a lot like the fuels we use now. Biodiesel has the ability to decrease our waste and reduce the amount of emissions we put into the atmosphere.

*In the absence of any catastrophic events that could cripple development (e.g. wars, natural disasters, etc.), our world will look drastically different by 2065, especially if we embrace sustainable development. Firstly, our population will seemingly continue to grow at an excessive rate, which will certainly influence how we progress with the development of our cities. For example, in NYC both the Brooklyn and Manhattan skylines have changed significantly within the past ten years (I have witnessed this from my roof), in that there have been numerous new high-rise constructions (and the new trend, i.e. “pencil skyscrapers”). The growing trend is to increase the population density, thereby necessitating the replacement of various smaller buildings. Thus, by 2065 there will certainly be vastly more high-rise buildings, and a much higher population density in cities. The actual buildings will be incredibly efficient, and will most likely be able to generate most if not all of their energy requirements. This will likely be attained through photovoltaic devices, such as the conventional solar panels on rooftops, but also with transparent photovoltaic “windows” (which maximizes the solar energy production capacity of buildings). There will also hopefully be other various renewable energy sources incorporated into these futuristic buildings, such as more efficient and appropriate wind energy devices (e.g. like the wind tower in Masdar city). Transportation within cities will also improve, with a greater emphasis on public transportation, and radically different personal commuter devices (e.g. the SoloWheel, which is an intriguing self-balancing unicycle Segway commuter). In terms of our usage of matter, it will hopefully no longer be a linear flow, and it will be cyclic with recycling being the last resort. Products will hopefully have longer lifespans, and companies and consumers will change their behaviors (eliminating overconsumption, and the concept of built in obsolescence). Thus, cities will experience immense changes that will completely revamp the cityscapes that we have become accustomed to.  
  
*This is very interesting. I like the idea of using old cooking oil as fuel, because it allows us to recycle from one process (cooking) and use the remains to run our car. It is beneficial to our environment as well! It does not contain any petroleum like the fuel we use now, and it will cut down on CO2 emissions. This would be great for the future.

Small towns will certainly experience considerable growth, however, I feel that a self-sustaining Mars colony will not really be feasible by 2065. I think that interplanetary (as well as asteroid) mining and resource acquisition ventures will be a reality, but I am skeptical that an actual “space-city” will be a possibility by 2065 (maybe some sort of space station that is the size of a town, like The Ark in the show The 100). Small towns will change significantly in a number of ways. For example, they will likely all be powered by sustainable microgrids, and most of the houses that surround these towns will likely be off the grid. The surrounding areas of these towns will be more pertinent in the future, as these are the agricultural production areas, which will have to successfully and sustainably produce food for significantly more people (which will of course depend on the ability to greatly increase the yields per given area of land, most likely through genetic modifications). Therefore, both cities and towns will change considerably, however, I think more time is required before we will have “space-cities” and hover cars (like in the show Futurama).

*I really like the idea of replacing fossil fuels for cars with cooking oil. Not only would it benefit the environment but it would also run cheaper for the consumer since it's waste that will be produced whether or not it's being reused.  Also it would be very feasible because it wouldn't be too big of a change for people to make from fossil fuels.

*I have to agree on you with the small towns being powered by microgrids, this would be an efficient way to power small towns that don't need large amounts of power such as big cities. I also believe that 2065 is too short of a time frame to make it to Mars and create a colony, we should rather focus on creating a better planet earth and using our resources sustainably.

*This is a great idea I know that it is possible to do now but I'm not sure how easy it is to switch over the engine so it can use this type of fuel. I know I've heard of people being able to use leftover french fry grease to run their cars! That's a great point about the waste being reduced for something useful.

:*Thanks for your vision!  But aren't we supposed to have flying cars?!  We were supposed to get those by 2000!  More seriously, I especially like your vision of the small towns being self-sufficient in energy and food. In the question I only meant a starting Mars colony equivalent to Roanoke or Plymouth - perhaps 100 people at most, as I agree a space city is very unlikely. [[User:Walkerma|Martin A.

By 2050 I would like to see willow plants used as biofuel.  As seen in Dr. Ewy’s video willows are viable during winter and are capable of growing on poor soil.  The technology is already being put to use, it would just need to become more accepted and widespread.  This type of technology is capable of having a large impact on our global environment.  Fuels that are currently used to heat most homes and run various modes of transportation emit large amounts of pollution, with willows replacing those fuels pollution could be dramatically reduced.[[User:KatieLaVoie|KatieLaVoie]] ([[User talk:KatieLaVoie|talk]]) 21:58, 7 August 2013 (EDT)
 
  
*Katie, this is a great idea! Especially because we have such brutal winters in the north country. It would be nice to see such a sustainable crop come from this area that can also provide a large revenue. [[User:AbbyL|AbbyL]] ([[User talk:AbbyL|talk]]) 13:00, 8 August 2013 (EDT)

I imagine that in 2065 the world will indeed be a much different place, and a place where everything we do is in a sustainable manner, and any resources we use will be renewable. I also would like to think that by then we will have a colony on mars that is also self sustaining. This would be an amazing thing to be accomplished by people, and a way to really prove how we have mastered being sustainable. I think all cities will be modeled after the new city of Melbourne where everything will be self sufficient sustainable, and green. I think this will be a amazing thing to see, everyone will need to work together to achieve this goal, making the world a better place.

*Katie, I to agree with you that the use of willow as a biofuel in the future would be something very promising. There is so much marginal land that isn;t being used for farming that if the right willow is grown in these areas and can be processed close to the source than it could make a very large dent in our use of fossil fuels.

*Willow plants as biofuel was definitely a very interesting point that we talked about in this course. I never realized how sustainable the willow plant is and how it could be used as a biofuel. The willows would definitely be able to supplement a lot of fuel we currently use to decrease pollution. ([[User:Magenta|Magenta]] ([[User talk:Magenta|talk]]) 10:16, 9 August 2013 (EDT))

I would like to see multiple aspects of the Melbourne model implemented in the new cities of the future. First I would for sure like to see the big public transport network, and lots of things that are walkable of each other. these two things would cut down greatly on the CO2 emissions due to cars. I would also like to see the city wide usage of recycling programs and increased education of how to properly recycle. Finally I would like to see the usage of the water catchment and usage of storm waters in the city to help cut down there using of natural spring and ground water, or fresh water lakes.

:*Thanks for the clarification.  I think cities like Melbourne and Portland, that are intentionally trying to blaze a trail in sustainability, will be able to serve as powerful examples for other cities to follow.  Other places are doing the same at the small-town level, too.  These examples can be very influential and -if they're successful (which I think many are) - can help to discredit the naysayers who say we have to do things the old way. I especially like the water idea, as water is a major problem in much of Australia now, with places like the Murray river (just west of Melbourne) running out of water.  [[User:Walkerma|Martin A.

*Two-thirds of the rural population of Africa, which has a combined population of over 1 billion people, lack access to drinkable water; and each day almost 35,000 people worldwide die from water related illnesses. In fact, more children die from water-borne illness like cholera and diarrhea than die as a result of war. Diarrhea alone causes more than 1.6 million deaths each year; and most are children younger than five.In countries like Mexico and Bangladesh, much of the water contains dangerous contaminants like pesticides, sewage, medical waste, and arsenic. That same water is then used for irrigation, contaminating the fruits and vegetables that they eat.[[User:Haw7thorne|Haw7thorne]] ([[User talk:Haw7thorne|talk]]) 02:35, 9 August 2013 (EDT)

In 50 years, I believe a self sustaining city would be built in a way that makes everything accessible and in walking distance. Homes and buildings will be built with solar panels and wind turbines, and will be insulated to increase home heating efficiency. The city would be designed in way that promotes riding a bicycle as means of commuting to work, I know Montreal makes this effort by having bike lanes, and bikes parked on the side of the road for rent. There would also be transportation in the form of energy efficient railways that are set up all over the country to allow for fast and efficient travel of long distances. As for manufacturers, they would all need to create greener process that produce no waste, or find ways so that waste can be a feedstock for another process. Recycling infrastructure would be in place to allow for this, and products will be made durable and environmentally friendly. Full cost accounting would be mandatory, and this would allow the green industry to flourish. The use of fossil fuels will be decreased, and it will become costly to continue using them. Cars would all be replaced with hydrogen fuel cell cars, and gas stations replaced will charging stations that utilize renewable energy as fuel.

One green technology I would like to see is better water purification systems in countries that need them the most. This will create more equal living standards for all people on earth. This is a basic necessity that all people have a right to so I think that by 2050 we should be able to deliver that standard. The technology would have to be easily used and assembled because many rural communities won't have access to certain technologies that would fix a broken water purifier. This would help to create clean water and a better environment for many people. ([[User:Magenta|Magenta]] ([[User talk:Magenta|talk]]) 18:06, 7 August 2013 (EDT))

*:I am a big fan of creating bike friendly cities, and have personally witnessed an incredible amount of progress in NYC (I have abandoned using public transportation, and have been commuting with my bike for the past 8 years)! For example, there are many more protected bike lanes, as well as the new Citi Bike program (which I helped advertise for at their initial launch with my cousin's guerrilla marketing firm). I also love what they have done in Montreal (the Citi Bike equivalent), which allowed me to easily tour the city on a bicycle (without emitting any carbon)! I also think it is a great idea to replace all of the gas stations with renewable energy charging stations (kind of life the Tesla supercharger stations).

*Magenta, there are a few ways water gets purified. I assume you would want to use green water purification which would involve treating water without adding anything to it. When we did our ACME presentations I talked about two possible ways to treat water, one being ozone and the other with UV light. Would you want to use methods like this? Also, above you said they won't have access to fix broken purifiers, so how would you make sure these systems are maintained? Overall I like any process that does not contribute to pollution and use a lot of energy, and green water purification is a great method to obtain clean water. :D[[User:Angela.M.Caracci|Angela.M.Caracci]] ([[User talk:Angela.M.Caracci|talk]]) 22:42, 7 August 2013 (EDT)

::*Transportation is a major issue, and many modern cities are designed around the car, esp. in North America, but this creates places that are unfriendly and contain fractured communities. If you design your city to make it sustainable and "livable" (as Melbourne seeks to do) so that you can walk or bike between places more easily, it becomes a lot friendlier as a place to live.  Public transportation is extremely efficient at moving large numbers of people around at low cost, and it's tragic that many cities lost what was a good infrastructure of trams and trains.  (Remember, most Americans used to use public transportation all the time.)  In my home city of Newcastle, they built a [http://www.nexus.org.uk/metro new Metro system] in the late 70s-80s, and when the first line opened they reckoned it removed about 50,000 cars from the roads.  They also reckoned it saved 1-2 million pounds (about 0.5% of the building costs) in healthcare costs because of fewer injuries from car accidents!  [[User:Walkerma|Martin A. Walker]] ([[User talk:Walkerma|talk]]) 14:58, 7 August 2015 (EDT)
  
*Yes your ideas in the presentation would definitely be viable methods! When I said that they wouldn't be able to fix it I simply meant that when they received the technology of the purifiers we would have to ensure that people knew how to fix it if it got broken. In one of the powerpoints I remember that some rural communities would get great technology but when it broke down there was no one who could fix the machinery! I just meant we would have to be sure that this would problem would not happen again. ([[User:Magenta|Magenta]] ([[User talk:Magenta|talk]]) 10:19, 9 August 2013 (EDT))

*I agree! I always try a think of ways countries like us can help poorer countries. I would be great to see countries like Nicaragua, who have almost no clean drinking water and no resources to obtain it, have clean water. Seeing as how water is the number one thing we need to sustain life it is not right that not all countries have it available to them. Water purification systems that need very little technology would be ideal because they would be simple to use and hopefully less expensive.

*I think that what would help us most is a more sustainable, nationwide hydrogen-fueled, high-speed/light rail system. I think that this would greatly improve our ability to use less energy, leaving less waste and mitigating the many negative impacts that we currently have on the ecosystem. I would start by soliciting the expertise and money found in the private sector; innovators, businessmen etc. I would then likely create a fund matching program whereby the federal government would match the funds raised by the pilot cities and their investors in order to instigate its growth. Lastly, I would organize a state subsidy rewarding drivers who have will sell their cars and rely in totem on the light/high speed rail system to travel within and between cities and states for at least two-years.[[User:Haw7thorne|Haw7thorne]] ([[User talk:Haw7thorne|talk]]) 23:57, 7 August 2013 (EDT)

For instance, I think that we could use a few trees in downtown Potsdam, but if we also had a problem with high concentrations of arsenic in the local water supply I would likely rather spend the towns money and time restoring our watershed.

The world in the year 2065 will be drastically different and I am hoping it will be for the better!  If we have made a successful switch to sustainable development then we will see cities and small towns utilizing the power of renewable resources in even more innovative ways then we already presently see today.  We will have different modes of transportation using solar and hydrogen power. We will see buildings utilizing solar power and "green" design features. We will see products designed and constructed based on green chemistry/design principles. There will be more technology designed to harness the power of the wind, waves, and sun.  Chemistry will be helpful in producing more efficient fuels for us to use to power our vehicles and buildings. Major developments usually occur faster when there is a crisis or a tragedy that happens, but I hope that will not be the source of the changes we will see. I am hoping our future holds great possibilities because we as a people see a need for a change in how we interact with the world that we live in. We need to realize that nature's forces can be helpful and that if we do not accept it's help it will eventually get mad and fight back!  Climate change is a real thing and more major natural disasters are occurring including:  earthquakes, violent tornadoes and thunderstorms, tsunamis, and volcanic eruptions. Just as we have had to develop new technology and designs to answer to our natural disasters, we will have to find solutions to answer this growing problem of global warming and climate change!

*I think it will for sure be cool to see how things change by 2065, if things are like you say and we actually make changes for the better this world will be a truly amazing place to be in.

I doubt the road ahead will be all rosy, but I also am hopeful that we won't reduce the world to nuclear dust or a baking climate with destroyed ecosystems.  In the C20th we learnt how to reduce many other types of pollution and we avoided the loss of the ozone layer; the present challenges are greater, but so are our resources and our knowledge.

I think one viable green technology that I would like to see adopted widely by 2050 is the introduction of plants and vegetation into urban areas. I understand that this isn't really a technology but it can be seen as one. I know that in places like New York City they have converted old, unused above ground subway and rail tracks into eco-gardens and walkways. They provided a space for people to walk and enjoy nature in an urban setting. I think if a lot more buildings or unused areas can become these eco-garden sanctuaries then there could be a positive effect on our global environmental footprint. By planting more trees and plants in areas that are now abandoned it would be better than just letting everything rot and decay. It would provide people a way to connect top nature again while helping the environment. [[User:Slomasa192|Slomasa192]] ([[User talk:Slomasa192|talk]]) 13:39, 8 August 2013 (EDT)

You have a lot of work going on, so this discussion is straightforward.

Dream a little! Imagine a world in the year 2065 where society has successfully made a switch to sustainable living. What would a sustainable city look like? How about a sustainable small town? A self-sustaining Mars colony? Describe some details/specific features you would expect to see. You can assume that technology has made major developments that can be extrapolated from today, but we will not consider major disruptive changes such as the Singularity which are hard to predict & assess. I recommend completing Unit 14 before posting.

Post an answer by 11:59pm on Wednesday, August 5th, 2015. Then post one followup comment on another student's answer by noon on Friday, August 7th, 2015.

  • In the absence of any catastrophic events that could cripple development (e.g. wars, natural disasters, etc.), our world will look drastically different by 2065, especially if we embrace sustainable development. Firstly, our population will seemingly continue to grow at an excessive rate, which will certainly influence how we progress with the development of our cities. For example, in NYC both the Brooklyn and Manhattan skylines have changed significantly within the past ten years (I have witnessed this from my roof), in that there have been numerous new high-rise constructions (and the new trend, i.e. “pencil skyscrapers”). The growing trend is to increase the population density, thereby necessitating the replacement of various smaller buildings. Thus, by 2065 there will certainly be vastly more high-rise buildings, and a much higher population density in cities. The actual buildings will be incredibly efficient, and will most likely be able to generate most if not all of their energy requirements. This will likely be attained through photovoltaic devices, such as the conventional solar panels on rooftops, but also with transparent photovoltaic “windows” (which maximizes the solar energy production capacity of buildings). There will also hopefully be other various renewable energy sources incorporated into these futuristic buildings, such as more efficient and appropriate wind energy devices (e.g. like the wind tower in Masdar city). Transportation within cities will also improve, with a greater emphasis on public transportation, and radically different personal commuter devices (e.g. the SoloWheel, which is an intriguing self-balancing unicycle Segway commuter). In terms of our usage of matter, it will hopefully no longer be a linear flow, and it will be cyclic with recycling being the last resort. Products will hopefully have longer lifespans, and companies and consumers will change their behaviors (eliminating overconsumption, and the concept of built in obsolescence). Thus, cities will experience immense changes that will completely revamp the cityscapes that we have become accustomed to.

Small towns will certainly experience considerable growth, however, I feel that a self-sustaining Mars colony will not really be feasible by 2065. I think that interplanetary (as well as asteroid) mining and resource acquisition ventures will be a reality, but I am skeptical that an actual “space-city” will be a possibility by 2065 (maybe some sort of space station that is the size of a town, like The Ark in the show The 100). Small towns will change significantly in a number of ways. For example, they will likely all be powered by sustainable microgrids, and most of the houses that surround these towns will likely be off the grid. The surrounding areas of these towns will be more pertinent in the future, as these are the agricultural production areas, which will have to successfully and sustainably produce food for significantly more people (which will of course depend on the ability to greatly increase the yields per given area of land, most likely through genetic modifications). Therefore, both cities and towns will change considerably, however, I think more time is required before we will have “space-cities” and hover cars (like in the show Futurama).

  • I have to agree on you with the small towns being powered by microgrids, this would be an efficient way to power small towns that don't need large amounts of power such as big cities. I also believe that 2065 is too short of a time frame to make it to Mars and create a colony, we should rather focus on creating a better planet earth and using our resources sustainably.

  • Thanks for your vision! But aren't we supposed to have flying cars?! We were supposed to get those by 2000! More seriously, I especially like your vision of the small towns being self-sufficient in energy and food. In the question I only meant a starting Mars colony equivalent to Roanoke or Plymouth - perhaps 100 people at most, as I agree a space city is very unlikely. Martin A.

I imagine that in 2065 the world will indeed be a much different place, and a place where everything we do is in a sustainable manner, and any resources we use will be renewable. I also would like to think that by then we will have a colony on mars that is also self sustaining. This would be an amazing thing to be accomplished by people, and a way to really prove how we have mastered being sustainable. I think all cities will be modeled after the new city of Melbourne where everything will be self sufficient sustainable, and green. I think this will be a amazing thing to see, everyone will need to work together to achieve this goal, making the world a better place. Rileytc197 (talk) 12:27, 3 August 2015 (EDT)

  • So you would follow the Melbourne example? What specifics do you like about the Melbourne model that you would like to see replicated elsewhere? Martin A. Walker (talk) 13:01, 3 August 2015 (EDT)

I would like to see multiple aspects of the Melbourne model implemented in the new cities of the future. First I would for sure like to see the big public transport network, and lots of things that are walkable of each other. these two things would cut down greatly on the CO2 emissions due to cars. I would also like to see the city wide usage of recycling programs and increased education of how to properly recycle. Finally I would like to see the usage of the water catchment and usage of storm waters in the city to help cut down there using of natural spring and ground water, or fresh water lakes. Rileytc197 (talk) 19:22, 3 August 2015 (EDT)

  • Thanks for the clarification. I think cities like Melbourne and Portland, that are intentionally trying to blaze a trail in sustainability, will be able to serve as powerful examples for other cities to follow. Other places are doing the same at the small-town level, too. These examples can be very influential and -if they're successful (which I think many are) - can help to discredit the naysayers who say we have to do things the old way. I especially like the water idea, as water is a major problem in much of Australia now, with places like the Murray river (just west of Melbourne) running out of water. Martin A. Walker (talk) 14:58, 7 August 2015 (EDT)

In 50 years, I believe a self sustaining city would be built in a way that makes everything accessible and in walking distance. Homes and buildings will be built with solar panels and wind turbines, and will be insulated to increase home heating efficiency. The city would be designed in way that promotes riding a bicycle as means of commuting to work, I know Montreal makes this effort by having bike lanes, and bikes parked on the side of the road for rent. There would also be transportation in the form of energy efficient railways that are set up all over the country to allow for fast and efficient travel of long distances. As for manufacturers, they would all need to create greener process that produce no waste, or find ways so that waste can be a feedstock for another process. Recycling infrastructure would be in place to allow for this, and products will be made durable and environmentally friendly. Full cost accounting would be mandatory, and this would allow the green industry to flourish. The use of fossil fuels will be decreased, and it will become costly to continue using them. Cars would all be replaced with hydrogen fuel cell cars, and gas stations replaced will charging stations that utilize renewable energy as fuel. Rodrigaf197 (talk) 17:05, 5 August 2015 (EDT)

  • I am a big fan of creating bike friendly cities, and have personally witnessed an incredible amount of progress in NYC (I have abandoned using public transportation, and have been commuting with my bike for the past 8 years)! For example, there are many more protected bike lanes, as well as the new Citi Bike program (which I helped advertise for at their initial launch with my cousin's guerrilla marketing firm). I also love what they have done in Montreal (the Citi Bike equivalent), which allowed me to easily tour the city on a bicycle (without emitting any carbon)! I also think it is a great idea to replace all of the gas stations with renewable energy charging stations (kind of life the Tesla supercharger stations). Alexanderlevitz (talk) 16:34, 6 August 2015 (EDT)
  • Transportation is a major issue, and many modern cities are designed around the car, esp. in North America, but this creates places that are unfriendly and contain fractured communities. If you design your city to make it sustainable and "livable" (as Melbourne seeks to do) so that you can walk or bike between places more easily, it becomes a lot friendlier as a place to live. Public transportation is extremely efficient at moving large numbers of people around at low cost, and it's tragic that many cities lost what was a good infrastructure of trams and trains. (Remember, most Americans used to use public transportation all the time.) In my home city of Newcastle, they built a new Metro system in the late 70s-80s, and when the first line opened they reckoned it removed about 50,000 cars from the roads. They also reckoned it saved 1-2 million pounds (about 0.5% of the building costs) in healthcare costs because of fewer injuries from car accidents! Martin A. Walker (talk) 14:58, 7 August 2015 (EDT)

The world in the year 2065 will be drastically different and I am hoping it will be for the better! If we have made a successful switch to sustainable development then we will see cities and small towns utilizing the power of renewable resources in even more innovative ways then we already presently see today. We will have different modes of transportation using solar and hydrogen power. We will see buildings utilizing solar power and "green" design features. We will see products designed and constructed based on green chemistry/design principles. There will be more technology designed to harness the power of the wind, waves, and sun. Chemistry will be helpful in producing more efficient fuels for us to use to power our vehicles and buildings. Major developments usually occur faster when there is a crisis or a tragedy that happens, but I hope that will not be the source of the changes we will see. I am hoping our future holds great possibilities because we as a people see a need for a change in how we interact with the world that we live in. We need to realize that nature's forces can be helpful and that if we do not accept it's help it will eventually get mad and fight back! Climate change is a real thing and more major natural disasters are occurring including: earthquakes, violent tornadoes and thunderstorms, tsunamis, and volcanic eruptions. Just as we have had to develop new technology and designs to answer to our natural disasters, we will have to find solutions to answer this growing problem of global warming and climate change!

  • I think it will for sure be cool to see how things change by 2065, if things are like you say and we actually make changes for the better this world will be a truly amazing place to be in.

We as a people can only ignore the signs for so long that we need to change our ways before we finally will. Rileytc197 (talk) 12:18, 6 August 2015 (EDT)

  • You're right that the consequences of 'not moving in this direction are not simply dirty, unfriendly, expensive cities & towns, but we will be living with the consequences of climate change and the human (and natural) catastrophe that follows. I doubt the road ahead will be all rosy, but I also am hopeful that we won't reduce the world to nuclear dust or a baking climate with destroyed ecosystems. In the C20th we learnt how to reduce many other types of pollution and we avoided the loss of the ozone layer; the present challenges are greater, but so are our resources and our knowledge. I hope that chemistry can help in making the world better, not worse! Martin A. Walker (talk) 15:11, 7 August 2015 (EDT)
