Stop sitting in front of a computer monitor and go outside. Plant something. Anything at all!
Smell the air, marvel at the blueness of our sky, lie on the ground and watch the clouds.
Try not to be wasteful. Reuse what you have and recycle what you can no longer make use of. Try to eat food grown by people you have met. Ride your bike. Walk. Live simply.
And, finally, two of my favorite quotes:
"I believe a leaf of grass is no less than the journey-work of the stars." Walt Whitman
"One touch of nature makes the whole world kin." William Shakespeare
Happy Earth Day, my friends!
