the human impact on the enironment is huge. we are distroying our enironment and others faster then we can think of. the acid rain that we make every time we drive our cars is killing the rain forest and other wild life suronding us.

when humans were realsing little carbon dioxide the rain forest was growing and there was water deep down into the soil. when the carbon dioxide realse rate was high in 2005 the trees couldnt get enough water and the leaves would realese carbon dioxide because they were departed from the trees. humans

I never understood the impact that carbon dioxide has on the overall environment. None the less the impact that individual households are held responsible for.

When humans have an impact on the envorinment, bad things tend to happen. The carbon dioxide we put into the air hurts the ozone layer, and many other things. We are killing the rainforest when we do this, and wse are destroying other animals habitats. For other animals that need the trees to get air or anything else, they cannot use that for survival. The carbon dioxide level has reached its high, and now that were learning about it more, we can try our best to stop what we have started.

the things that humans do is very important even if we dont relise it. everything that we do has a reaction it could be good or bad, and just putting on hairspray or spraypainting a wall is ruining the ozone and that is hurting us as well as the environment because now we have to be even more carful about going out in the sun beause it is becommig eaiser to get cancer if u dont have some type of pretectyion from the suns rays.
