Tree Facts

Trees are the longest living organisms on the planet, and one of Earth’s greatest natural resources. Trees provide food, medicines and materials. They moderate climate, improve air quality, conserve water and harbor wildlife. We could not live without trees because they take carbon dioxide from the air and replace it with oxygen. Trees provide protection for all beings.

“The best time to plant a tree was 20 years ago. The second best time is now.” – Chinese Proverb
