what you know about the role of forest in the world

lol. The forest/jungles/general vegetation are important to the earth/the creatures on it, including us. They account for much of the oxygen produced and CO2 recycled. they help regulate temperature in the atmosphere and provide homes and food for animals as well as humans. we get many of our cures/vaccines from jungles/vegetation. We use the trees and plants in many industrial processes like making paper to making clothes, etc.

There is a widespread assumption that forests help to maintain constant supplies of good quality water. Loss of forests has been blamed for everything from flooding to aridity and for catastrophic losses to water quality. In fact, the hydrological role of forests is complex and the precise impact on water supply varies dramatically between places and can also vary in one place depending on such factors as the age and composition of the forest. Forests in watersheds generally result in higher quality water than alternative land uses, if only because virtually all alternatives – agriculture, industry and settlement – are likely to increase the amounts of pollutants entering headwaters. In some cases forests also help to regulate soil erosion and hence reduce sediment load, although the extent and significance of this will vary (Aylward, 2000). While there are some contaminants that forests are less able to control – the parasite Giardia for example –forests usually reduce the need for treatment. Where municipalities have protected forests to protect water supply, it is issues of water quality that have generally been the primary driving force.
