If the temperature increases it will lead to heat waves. The ice arctic will melt and the polar bears will not have a homes. The plants and the tress will not grow and we need trees because of the CO2. If the oceans, temperature increase there will be Tornados. Some areas will be converted into a desert. Some animals species will be extinct because of the change in the environment. And many more.....
We can help the temperature by not killing trees because of CO2. Use Less factories. Less using cars. Grow trees and planets. Use less electricity by thatI mean when your not usingA light in a room just turn itOff.
