Kermit the Frog has been saying for years that it's not easy being green and frog lovers are trying to drive that point home today.

This is the sixth year that the last Saturday in April is being celebrated as Save the Frogs Day. 

Conservation groups around the world are holding events to draw attention to threats that have more than two-thousand species of frog on the brink of extinction. 

That's roughly a third of all the frog species in the world.
