Today's tip is so easy, we hope you do it four or five times in the next couple of hours! Our tip today is to say "Thank You." There are thousands of people across the world that dedicate their day to green issues. Many of them do it on a volunteer basis or for very little money. They do it because it is their passion.

That doesn't mean, however, that the jobs aren't tiresome. It doesn't mean that people can go non-stop without some sort of support. We often underestimate how powerful those two little words are. A person that is about to make a big (and positive) impact on our environment might be one minute away from throwing in the towel. Let's hope they receive their thank you in time.

So go on, give a thank you to someone in your local community, or someone tackling a specific issue you think is so important. Even encourage a new green business to keep hanging in there. Your words are more powerful than you think.

Rebecca says: This tip comes from the heart as I know how good it feels to be on the receiving end of these thanks. Don't cheat and thank us, however. Really think about who you should thank. Maybe it should be community members who have worked tirelessly to create an incredible Earth Day celebration for you. Maybe it is the retiree who teaches organic gardening classes. Or maybe it's that lady that takes her daily walk with a bag in hand to pick up litter. Don't delay, thank today!
