(A) Trees:
Our Best FriendsTrees fulfil almost all our basic needs. They provide us with food in the form of fruits and give us shade on sunny days. They filter the air by absorbing carbon dioxide from the air and releasing oxygen. They block the strong rays of the sun preventing them from reaching the ground. In this manner they maintain the temperature of the earth keeping it cool. Trees are also the most effective preventers of soil pollution. Roots of trees hold firmly on to the earth and prevent it from getting eroded during rains. Thus, trees are the biggest blessing given to man by God. We should therefore be grateful for this blessing and preserve it for our future generations.
