Trees and forests are very important to the environment. In addition to holding water, trees hold the
soil in place. Trees use carbon dioxide (CO2) and give off oxygen (O2), which human beings, animals and
plants need for survival. Besides, they provide homes and food for millions of types of animals.
Cutting down large numbers of trees, to use the land for something instead of a forest, is called
deforestation. Although people often have good reasons for cutting down trees, deforestation can have
serious effects. In the Amazon rainforest in South America, for example, thousands of plant and animal
species are being lost before scientists can even learn about them. In the Pacific Northwest, there is a
conflict between logging companies that want to cut down trees for lumber and people who want to
preserve the ancient forests.
People cut down trees for many reasons. When the population grows, people cut down trees to clear
space to build houses, schools, factories and other buildings. They also cut them down to be sold for
lumber and paper companies . Industrial pollution is also a chief cause of deforestation .Factories often
release poisonous gases into the air and dangerous wastes into the lakes and rivers. Air pollutants may
combine with rain and fall to earth as acid rain. Acid rain and polluted water can restrict plant growth or
even kill most plants in a forest which are essential for earth. As a consequence, cutting down trees
endangers the environment . When forests are cut down, the area grows drier, causing a change in the
local climate. If governments don’t take measures to punish the irregular timber companies, there will be
fewer forests in the world.
