Help fight climate change with this purchase! Trees are like the lungs of the planet...our "natural air purifiers." They breathe in carbon dioxide and breathe out oxygen. Additionally, they provide habitat for birds and other wildlife and play a vital role in our natural water cycle. Forests help regulate the water in the air through a process called transpiration. They absorb thousands of gallons of water into their roots. Excess water is then released through the leaves back into the air. For every purchase made, I donate one planted tree through Plant-It 2020. Small changes by individuals can make a difference in the fight against climate change.
