Write a note on how forests influence the quality of our air soil and water resources
Answers
Answer:
Forests influence the quality of air, soil and water, natural resources in the following ways : (i) Air - Forests have large number of trees, shrubs and herbs. They take in CO2 and give out oxygen during photosynthesis in daylight. Thus, they maintain the concentration of oxygen and carbon-dioxide in the atmosphere.

Lake Margaret, located south of the Lake Tahoe Basin, featuring the lake, two large boulders protruding from the water in the foreground, with conifer trees, a rocky mountain ridge, and blue sky in the background.Photo Credit: Tim Rains, U.S. ForestWater, air, and soil are three natural resources that we cannot live without. The Forest Service strives to protect, maintain, and restore these valuable assets now and into the future.
Water is one of the most important natural resources flowing from forests. The Forest Service manages the largest single source of water in U.S., with about one-fifth originating from 193 million acres of land which provides drinking water to 180 million people every day.
Soil provides nutrients, water, oxygen and heat to natural land areas. Understanding the ability and capacity of soil to support an ecosystem plays an important role in land management decisions.
Air is a third critical resource for humans, plants, animals and all other organisms within a natural area. Air must be monitored in order to control and lower pollution levels, control smoke caused by wildland fires, and to monitor air quality. The Forest Service monitors the effects of air pollution that may impair visibility, harm human health, injure trees and other plants, acidify or cause unnatural fertilization of streams and lakes, leach nutrients from soils, and degrade cultural resources, like archeological sites and historical buildings. Forest activities that can affect air quality such as prescribed burning, ski areas, and mining are also monitored to ensure compliance with air regulations for human health and to monitor possible impacts to natural resources.
What research is being conducted to protect these natural resources?
Research on water, air and soil provides scientists with information about these critical natural resources, how they are changing, and what is affecting them. Forest Service Research and Development focuses on the following four focus areas involving water, air and soil:
