Biodiversity!

Today in class we talked about Biodiversity! Biodiversity means that there has to be different organisms in the world.

We also talked about the hole in the ozone layer. We talked about how it is letting bad UV rays into the earth, but we also learned that because of the ban on DDT, especially in aerosol cans.

Another thing we talked about is that the polar ice caps are melting becasue of the Greenhouse Effect. The greenhouse effect traps heat in the earth and

makes it hotter. It's not always a bad thing though, because without it, the earth would become unbearably cold.
