There's a new article up on the Biology Site - Earth Day - What is Earth Day?

After you've had a chance to read the article, come on back here and join the discussion!

It was really a good article on the Earth's day. Thanks a lot.

Now we need a lots a Earth's day in a year,because of the polluted substances we are giving to the earth.

I agree wholeheartedly, Clenbut!
