Just after the demise of the dinosaurs, a small rat-like species of mammal (now known as a prosimian) left the ground and took to life in the trees. Eventually after 50 million years had passed, this creature returned to the ground as the ancestor of man. They give us timber to make furniture, to refresh air, to prevent soil erosion and flooding, to give in summer cool and clean air, source of products such as gum, paper, rubber, medicine, rain, etc.
For example, paper industries, rubber industries, match industries, etc., are totally dependent on trees for their economic survival.
The period spent in the environment of the trees was of great formative importance because it promoted many physical changes.
These changes included a massive increase in body size, the development of paws into hands and 3D color vision.
In short, we can say that trees are the most precious gift of nature that we have and we must save them so that our Earth can stay beautiful and our coming generations can enjoy the gifts by trees.
Trees are the earth's most precious and important source of life.
