Pls answer fast tomorrow is my exam

Trees are very important to our environment. It purifies air and also provides fruits, woods for human beings. But the ever-increasing population is destroying the existing forest cover, which in turn will lead to the destruction of humankind itself.
TREES ARE the largest and the longest living organisms on earth. To grow tall, the trees display miraculous feats of engineering and a complex chemical factory. It has the ability to absorb water and salts from the earth and transport them up to the leaves, sometimes over 400ft above. By means of photosynthesis, the leaves then combine the water and salts with carbon dioxide from the air to produce the nutrients, which serve as food for the tree. In this process, trees create wood, as well as many chemicals, seeds and fruit of great utility to man. Trees also remove carbon dioxide, the main greenhouse gas, from the air.
Trees are very important to our environment. Tropical rain forests are of particular significance; although they now occupy less than six per cent of the land surface of the earth, they sustain more than half of the biological species on the planet.
Did you know that forests are called the lungs of the environment? They are a factory of oxygen and various other very important natural resources. Can humans live without their lungs? Similarly, the environment too would not survive without forests.
Forest conservation as the name suggests is the preservation and the protection of forests. It also involves the reversal of deforestation and environmental pollution. The preservation of all natural resources is absolutely essential for the balance of our ecosystem.
Importance of Forests
Let us take a look at why forests are so very important to us and our environment. We are basically dependent on forests for our survival. And so their conservation is of essential importance.
The most important function of forests is that it produces mass amounts of oxygen as a by-product of photosynthesis. Oxygen is the main respiratory gas for all animals, it ensures our survival.
And while photosynthesis, trees also absorb carbon dioxide from the air. This is one of the main pollutants of air pollution. Hence forests also reduce air pollution.
Forests also prevent soil erosion and keep soil pollution in check. Deforestation, in fact, leads to soil erosion on a large scale since the topsoil comes loose.
Forests also play an important part in the water cycle and control moisture levels of our ecosystem.
And finally, forests are the natural home and habitat for millions of species of animals, birds, and insects.
Ways to Conserve the Forest
Controlled Deforestation
While deforestation cannot be avoided completely, we must look to control it. Young and immature trees should not be felled as far as possible. We must look to avoid large-scale commercial deforestation as well. Adapting practices such as clear-cutting or selective cutting will be beneficial in the long run.
Protect against Forest Fires
Forest fires are the most common and deadly cause of loss of forests. They can start due to natural causes or can be accidents caused by man or even intentional in some cases. Once a fire spreads in a forest it is very difficult to control. Precautions must be taken for such incidents. Making fire lanes, spreading chemicals to control fire, clearing out dry leaves and trees etc.
