Let's face it, we love to "do it."  The thought of getting laid is what helps some of us get through the day.

It is estimated that the human populous, as a whole, has sex 215 million times a day.  Wow, that's a lot of nooky. 

Robert Engelman, author of the new book More, says that because of all this sex there are about 78 million people born a year.  The problem? All these new bodies are going to put an even greater strain on our ever troubled environment. 

So, be green and use condoms (or other baby preventing devices).  Do your part and stop popping out so many kids!
