Earth is home to all of us, no matter what. So let's treat it right every day, and not just once a year. Happy Earth Day!
Love the Earth? The do something to make the world a better place! Carpool -- Fit as many people as you can into that Hybrid to cut down on emissions during your daily commute. Plus, it'll save on gas money.
Clean out that closet -- There could be plenty of stuff that you just don't need, so why not donate it to the Purple Heart? There are plenty of people out there who'd appreciate it.
Plant a tree
Pop in an energy efficient light bulb at your house. You'll do it once, forget about it, and it'll save tons of energy. Little changes go a long way!
Crack open a window -- Heaters and air conditioners run constantly and require alot of energy. Weather permitting -- why not open up a window to catch a nice breeze?
Go outside and play -- Instead of sitting in front of a computer all day or watching TV, grab a friend and go for a walk, have a catch or go fishing.
