We are cutting a lot of trees per day for paper and house furniture. We should planted 2x the trees we cut down and trees clean air for us since we had gas’s cars there is a lot of  pollution in the air it the is less clean air for us to breath. Take La, California for example in the air in morning you see black clouds which is gas. When the trees are being cut animals habitat are being destroyed every day we need to started planting more trees than we cut down which means animals can come back.
