I hope you are planning to do something special to celebrate Earth Day tomorrow. Anything you do will certainly contribute to the positive vibe we will all feel as we honor the 36th anniversary of a pivotal day in the history of our global environment. If you don't have anything special planned, check out the Web site of The Nature Conservancy. The site has two activities you can do right now. One is to share your message of hope. If you would first like to see what others have written, check out this week's Top 10. The Web site even posts honorable mentions in case 10 aren't enough. Another thing you can do at the Nature Conservancy Web site is send an E-card to friends and relatives to remind them that Earth Day is tomorrow. You might also plan some personal energy activism for tomorrow, such as keeping your lights off as much as possible, leaving the car at home and biking or walking somewhere, or turning down your thermostat (or up if you are lucky enough to live in an area where air conditioning is already being used). I'm sure you will think of something.
