It’s not too late to get involved in Earth Day, beyond just clicking the Google header and seeing what it says about this holiday.

In fact, this year the folks at Earthday.org are running a special initiative, inspired by all of those pledge and goal-tracking websites. They’re calling it ‘A Billion Acts of Green‘, and the idea is to get a billion people to pledge to doing something – anything – out of their normal daily routine that is good for the environment.

That could be going around and picking up trash, turning off the water when you’re brushing your teeth, or planting a tree.  Some companies have even gone so far as to pledge to plant a tree for every sale made on Earth Day, or to donate a portion of all sales made on Earth Day to a green charity.

So, they’ve haven’t quite made it.  They only have a little over 100 million pledges.  That’ll do for now, I guess.  You can either make your own pledge by clicking the button below, or you can browse the pledges made by others, and pledge the same thing – it’s the lazy man’s conservationism!

Whatever your motivation or energy levels, get involved this Earth Day.  The point of the Billion Acts of Green is not to get people changing the way they do things for one day – it’s to get people to pledge to change their behaviour slightly for the next year.  If 100 million people have already done it, then that will make quite a difference.
