A sustainable city needs much planning involved. Some things that I would think would be useful in a Sustainable City are Stricter laws in the Agriculture and Fossil Fuels Industries. Agriculture takes up many resources including space that forests may have been residing in, and gallons of water used up for our cattle to drink. The animals also release lots of methane, a type of greenhouse gas. As for the Fossil fuel industries, they release a large amount of CO2 into the atmosphere and heating up our one and only planet. Secondly, something else that would be useful in a sustainable city is better transportation. If we plan more in our bus and train services, we would not need to use our cars that often. Another thing that can help are repair shops. We live in a society that when something breaks, it is replaceable. Instead of replacing our broken stuff why don't we fix our items instead of buying new things. Last but not least Renewable Energy. Investing in rene  wable energy should be the number one thing that a Sustainable City needs. A city that runs on fossil fuels is not sustainable.

I agree with this discussion post because all of this is happening on the daily. We as a civilization damage our forest everyday so we could have more land to live on, and build more machines that pollute our Earth. Every hours 4500 acres of forest is destroyed by bulldozers, forest fires, and other machines to destroy the forest. So I think that is necessary to do things like recycling and reuse, and switch to bikes because all the little things will make a big difference.
