Trees are an essential part of our planet's ecosystem. They provide us with oxygen, absorb carbon dioxide, and help to regulate the climate. Trees also provide us with food, medicine, and materials for shelter and clothing.

 

One of the most important functions of trees is the production of oxygen. Trees absorb carbon dioxide from the atmosphere during photosynthesis and convert it into oxygen. This process helps to purify the air and make it safe for us to breathe. In fact, one mature tree can produce enough oxygen to support two people for an entire year.
