If you can, garden and compost. This helps save Mother Earth and your grocery bill. Your body will thank you for your organic produce feeding its energy system. This year when I saw how high the vegetables cost, I groaned. My mom's garden saved the day. 
Recycling is saving money and our precious resources. Many businesses have gone green and tried to implement all sorts of practices. I even know of a green website that features alternative practitioners. Cycle to work or to a friend's home if you can. You will feel better, Earth and air quality will improve. So hopefully our health overall will improve. I thank you for those who are already doing their part and commend those starting to do it today for the first time.
