Things About Earth

We have lived on Planet Earth all our life. But we never pay attention to it because we don’t care. Sometimes I don’t even notice I’m on it. Earth is in so much of a mess cause we have to many smoke stacks, people that litter, landfills, and so much more.

Problems

Problems with the earth today is pollution. Pollution is big. About 1% of the U. S. landfill space is full of disposable diapers, which take 500 years to decompose. Enough glass was thrown away in the 1990’s to make up the twin towers. Americans use 50 million tons of paper – consuming more than 850 trees.
