Can I please get a brief introduction on the topic 'conservation of forests'? Thank you!

Forest conservation, or forest protection, can come in two forms: Protected a forest from human interests, or sustaining a forest during times of natural threat, such as fire or blight.

The World Wildlife Fund describes forests as "the planet's lungs." and "essential to life on Earth." They and organizations such as the WWF strive to protect forests from aggressive logging and farming, and the encroachment of urban sprawls. One way this is done is to campaign for the creations of more national parks and areas of scientific interest and natural beauty.

The Needs of the World and the Need for Nature

Of course, we do need a certain supply of timber and natural materials. An important part of conservation is educating people on how to use such supplies in a way which protects as far as possible the Earth's natural resources. 

This could be by buying recycled paper products, or purchasing products made from wood harvested from sustainable sources, such as a certified forest or from a company that invests in a scheme to replenish woods and forests.

On the ground, the laws of the land regarding the protection of forests are enforced by foresters. The duties of a foresters include overseeing timber harvests, restoring damaged forest areas and overall management of protected areas.
