Tree guards are those people who are employed to safeguard the forests. They are mostly employed by the government but there are those who are employed by private institutions. It is important to employ the tree guards because the trees cannot be stolen or cut down without the government authority. If all trees are cut down the country or the world at large would turn into a desert. Trees are very important because they attract rainfall. Rainfall is necessary because without rain people cannot plant food crop which would result into drought. The wild animals would also have no place to live. This would mean all the rivers would dry up. To cut down trees one requires a permit from the government. The government ensures that once trees are cut down new ones are planted to replace those that have been harvested. Trees are harvested in phases to ensure that there is mature trees at all times.
