Trees provide breathable air, timber, fuel, food, shelter, medicine and beauty. Without trees, we could not live. They can help us think better — Plato and Aristotle did their best thinking in the olive groves around Athens, Buddha found enlightenment beneath a bo tree, and Isaac Newton realised his theory of gravity when an apple fell from the tree under which he was sitting — and they can help us feel better.
Many of today’s pharmaceuticals are derived from trees. Aspirin comes from willow bark; yews are the source of Taxol, used in the treatment of some cancers; ginkgo biloba improves circulation; tea tree oil is beneficial for skin infections; cinchona tree bark contains quinine, the basis of many anti-malarial drugs; and Pycnogenol, which protects against deep vein thrombosis, is made from pine tree bark.
the tree give us a clean air and a clean place and it make the place more nice the leaf when we see it it give us a good feeling and how are the life beatifull
