Trees, are our primary shelter from the very beginning of our mankind,
we have lived under the trees as our main shelter. We are protected from the direct sunlight, storm wind by getting under the tree.

As the saying goes, "The shadow of a tree can help saved hundreds of other creatures that shelter under it". The saying reflects the life of animals that depend on trees. Many animals accompany tree not only as their houses to stay but also as their main source of foods for most herbivores.

In this very modernize world, trees are used in other different places. Many of our daily usage of furnitures, papers and constructions are many of woods which is in one way taken from the trees. Trees get much useful for our people. So, it leads to over use and over cut and destruction of our main resource.

The world's most area is place my natural forests in the last decades, but in our time 21st century, most of the forests areas are destroyed by the act of people. We are the ones who destroy the main shelter of the world. If we don't replace or recover our act, in the few decades we will not get much benefit form our shelter.
