In a perfect city that is 100% environmental friendly there would be no pollution or any bad greenhouse gases released into the atmosphere. This means that the city would need to have no cars or any other motor transpiration systems. Since there would need to be no pollution there would also need to be no industries, but in society today you need industries to make money and survive to buy food so you can live. This would be very hard to achieve in our world today, we can prevent global warming by making some minor adjustments mentioned like using less motor based transportation.

My sustainable city would have electric and eco friendly cars and public transportation, also planes would be the only non eco friendly thing and I would try my best to figure out a more eco friendly system for planes. For lights, people would have lots of natural lights and lights that are built into their houses to turn on at certain times that you can set and times to turn off, like a built in electric home system that could contribute to turning lights off when you leave a room and help conserve electricity. I would have grocery stores with most organic food and yes there would still be food that’s not so good for you, but there would be lots of farmers markets and lots of locally grown food, just trying to improve the better foods than having Co2 produced in factories with junk food. My city would limit the prices of clothes and purchases but also still be enough to make a good income, just you would have to make multiple products and maybe have more sewn items and handmade items then all the clothes made in factories.

I think these are all excellent ideas. Building off the idea of eco-friendly planes, I think one solution would be the invention of airplanes that run on solar energy and have stored gasoline as a back up resource. These would ideally be set to automatically switch to running on gasoline when sunlight diminishes. This idea could also apply to cars, and you'd also
be able to switch sources manually if necessary. This concept can cut the amount of gasoline we use in half. One gallon of gas can release 20 lbs of carbon dioxide in the air. If transportation depended mainly on a renewable source, such as sunlight, humans can greatly lower our contribution to global warming and the greenhouse effect. source: https://www.fueleconomy.gov/feg/content … o2_inc.htm

These are all very good ideas. Expanding on the affordable clothes idea, I think that making your clothes is a great idea. You can also use thrift stores or a place where clothes get a second chance. There is also upcycling, which is when you take a item of your old clothing and make it new.

I like all of these wonderful ideas. Expanding on the locally grown foods, I think that in this city more people would grow some food with local gardens to even lessen the CO2 emissions used in transportation of foods. Also, many houses should have solar panels to use that energy in our homes. Overall, all of these ideas would create a very eco-friendly city.

i think this is a good idea but the transition from the city we've been living in to the city that we want would be tough

I agree with those ideas because if a whole city conserved resources like electricity and purchases the carbon footprint of that town would decrease by a lot.

If I were to design a sustainable city, there are several plans I would want to implement, and others I would not.  After doing an online sustainable urban planning activity, I learned that utilizing fuel cell technology is a great way to clean up transportation emissions, and I would plan for my city to have fuel cell buses and would create incentives for people to buy fuel cell cars.  In addition to fuel cell technology, I would build bike paths for people to safely bike in, thus reducing carbon emissions from cars.  In my city, I would also create financial incentives for both residential homes and commercial spaces to have solar panels and use solar energy.  I believe that people would like this alternative, as using solar energy is drastically cheaper than using fossil fuels in the long run, and people can even profit from using solar panels.  In my city, I would like to have wind farms but would be wary of where they would be placed, because wind farms can harm local ecosystems, especially offshore wind farms.  The one form of energy I would not want in my city wou ld be energy from hydroelectric and tidal plants because these plants can be detrimental to local ecosystems.  Overall, a city that utilizes fuel cell technology, bike paths, solar energy, and some wind energy would have virtually no carbon footprint and would serve as a role model for what green cities can look like.
