Trees are very valuable and useful to us. They give us flowers, fruits and fuel. Many types of furniture are made from the wood of the trees. Fruits, barks and leaves of a large number of trees and plants are used to make drugs and medicine. Research findings show that forty percent of American drugs come from rainforest plants. Quinine, an anti-malarial drug, comes from the bark of a tree. The snakeroot plant is used to treat hypertension and high blood pressure. Trees protect the land from river erosion. Man and other animals exhale carbon dioxide. The green leaves of the trees take in this carbon dioxide to prepare food, and give off oxygen. We cannot live without this oxygen. Trees help to prevent the greenhouse effect. They help to reduce global warming. They save our houses from storm and flood. They give us shade so that we can save ourselves. from the heat of the sun. But people do not understand the usefulness of trees. They cut trees indiscriminately. As a result the world is warming day by day. The pattern of climate is also changing. The Government of Bangladesh should take some steps to prevent deforestation.
