recycle and reuse plastics

use solar or wind power instead of fossil fuels

all of the above

20.

As carbon dioxide increases, temperatures decrease.

As carbon dioxide increases, temperatures increase.

Carbon dioxide concentrations have no affect on climate.

As carbon dioxide concentratons increase, temperatures become more random.
