Hey it's Earth Day. This year there is an effort to collect "a billion acts of green." . Currently they've collected over 100 million pledges.

Lots of the pledges are very doable:
. turn off the water while brushing your teeth
. wash all of your clothes in cold water (well not diapers)
. eat more local food
and my current favorite
. play outside instead of watching TV, saving few hours of electricity usage (I am so doing this one!).

So check them out, make a pledge and stick to it.
