issues in global warming are whether the cost of recycling is worth its cause.
I believe it is worth it because recycling conserves the earths resources. If we want the earth to last we need to save the resources.

Another issue is if global warming is caused by the greenhouse effect or by an unknown natural process. I personally believe that it is cause by pollution, because of scienctific research and proof.
