I don't think that we change the climate enough to affect the planet but we definitely can hurt things like rivers, lakes, beaches, wetlands, and forests by not being responsible with our resources and our actions. I don't think my truck is changing the climate for example but when we accidentally spill oil or something like that we can temporarily and sometimes permanently hurt that area so for that we should be more aware of what we are doing. I think the sun and earths cycles are the prime reasons for any warming or cooling though and not our lifestyle. It's crazy to me that for every scientist that says we create climate change there is another that says we aren't. Ultimately we should just all try to be less wasteful and appreciative of what God has given to us.
