Tree and forests create or produce fresh.

A tree has the ability to provide an essential of life for all living things on our planet – oxygen, and the power to remove harmful gases like carbon dioxide making the air we breathe healthier.

Explanation: To keep it simple a tree is comprised of its leaves, stems, trunk, and its roots.  When you look at a tree, note that about five percent of the tree is comprised of its leaves, 15 percent its stems, 60 percent goes into its trunk and 20 percent is devoted to its roots. Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree.  But as a by-product of that chemical reaction oxygen is produced and released by the tree.  It is proposed that one large tree can provide a day’s supply of oxygen for up to four people. Trees also store carbon dioxide in their fibers helping to clean the air and reduce the negative effects that this CO2 could have had on our environment.
