We all know that humans are doing horrible things to the Earth. Here are just a few of the very worst things that we are doing to the only planet we can currently live on.
Believe it or not, most of the Earth used to be covered by forests. That included about half of the US, 3/4 of Canada and almost the entire continent of Europe. And that wasn't all that long ago! But humans have chopped down a great deal of these forests to make room for themselves despite the fact that about 70% of the world's plants and animals live in forests. To this day about 32 million acres of forest are lost each year and at that rate the tropical rainforests which house 50% of the world's species will be gone in around 100 years.
