Go outside today, plant a flower, pick up some trash, breathe in the air. There are so many things you can do just to say "thank you Earth, thank you for giving me this place to live!"!
Also check out some of my favorite eco-friendly things (in no particular order):
Now I love Jason Mraz, I have since I was in 7th or 8th grade. Throughout the years I learned about how much Jason loves the earth. He has an avocado farm at his house, he can serve me avocados anytime. He has a blog where he has posted recipes (including how to make a delicious chocolate avocado treat). PLUS, he recently set out on a tour and made it his green-est tour yet. How many celebrities do you know that genuinely care about taking care of the environment? He is one of them.
I'll take Jason Mraz with the stainless steel water bottle in the bathroom (using ocean salt). Oh he's not the killer just helping the environment. See you could even make an eco friendly version of clue. Whatever you do today to celebrate the Earth make it meaningful, try to make it a part of your every day life and if you have little ones make sure they understand the importance of doing what we can to conserve what we have!
