I think that if we created more public parks, we would have more room to plant trees and other plants. We would also be using this space to preserve nature, instead of building a factory or apartment building that will produce CO2 emissions. What are some other ways we could use public parks to help with climate change?

i agree, i think the idea of more trees instead of factories is a great one, but other than that, i dont see any other things that the parks could do, any ideas?

Community gardens inside the parks?

but what would the gardens do for the co2?

Because plants use photosynthesis and one of the products in photosynthesis is CO2.

I agree with the idea for more Community Gardens/public parks. Community gardens provide a food source for people and along with what Tristan B has said above, plants use photo synthesis

i never thought of the food idea...

It also could reduce the amount of food being outsourced, and limit the amount of emissions.

I agree with the idea of course, but lets consider any negatives it might bring. For example, having more public parks instead of factories and apartments would reduce the amount of housing and jobs in that area. Having more parks would in general reduce the amount of co2 in the air but would also reduce the amount of space for people to live and work. Also most cities that really need more public parks often have lots of trash and homeless people in the parks they already have. So the parks might require an office to monitor them, which means more money spent.

The comment by Reid above highlights a big problem with making these changes in the world. For how good parks would be, we have to consider the entire picture.    These changes have to make sense economically as well, and other issues besides climate change need priority as well.

What, forgive me if this seems preposterous, would happen if we were to use the roofs of buildings to create little parks? That way, instead of having water run-off and storm drains we'd have something to slow down the descent of the water, and in addition maybe even use them for gardens?

Sebastian, that is already something people do. It is in no way preposterous. It also cools off the building's interior and has many other neat effects.

I think having a mix of having parks on the flat roofed buildings and a few public parks on ground level would work well because then there would be more plants but still parks for people to enjoy without having to climb up fifty flights of stairs.

I think more parks overall would be good for everybody not to mention the carbon emissions, more parks would allow more people to appreciate the beauty of nature and compel them to do some more research on how to preserve it.

Instead of having parks on roofs, I think we should create rooftop gardens.

also people would be more encouraged to go to parks if there was more/better parks. if more people are going to parks they are less likely to do other stuff that will produce carbon the atmosphere. for example if they are outside at these parks they wont be using the lights in their house.

Molly, those are pretty much the exact same thing.

If we make more community gardens in parks or completely separate that would kill two birds with one stone!

We should make it mandatory for every new building built to have either plants on the roof or solar panels.

...What would it take to make a garden? Like, expenses and work and such. These are wonderful Ideas, but what good is an idea without being put into action?
