The importance of forests
People live there, too. Forests purify soil, water and air Not only houseplants, but also forests purify the air of pollutants, including carbon monoxide, sulphur dioxide, nitrogen dioxide and fine dust. Uncontrolled clearing of forests from such upland areas, in addition to its local effects, can also have major repercussions further downstream.
On the one hand, an increase in atmospheric carbon and higher temperatures could result in increased growth rates.
More forests means less CO2 in the air and less global warming. Because trees, like all green plants, absorb carbon dioxide during photosynthesis, reforestation is often suggested as a means of countering the increase in greenhouse gases in the atmosphere. Trees can compete with crops for light and nutrients, causing significant reductions in crop yields.
Economic importance of forests
Enrich the Soil Plants and trees help to recycle the soil nutrients through the shedding of leaves and small branches. The world demand for timber and wood products has been growing at 1 to 2 percent per year over the past decade. If the tree is burned as fuelwood then a high proportion of fixed carbon is released, but if it is made into a durable product with a long-term use such as furniture then the carbon will remain fixed for a long time. Heating during winter months can also be reduced because trees can provide shielding from winds. They include those who have lived there for generations, often referred to as indigenous or tribal peoples; people who have recently moved into the area, often described as settlers, squatters or encroachers; and people who live part time in the forest working as small-scale loggers or harvesters of forest products. Without oxygen, life as we know it would not be possible. Forests also have an increasingly important role as havens for wildlife and for the protection of endangered species of plants and animals. The belief that trees are always benign elements in the farming landscape is also a myth. Figure The wildlife in forests can also make a major contribution to food supplies.
Between andthe world lost some million ha of forest, an area the size of South Africa. Forests provide jobs and incomes The economic value of the services provided by forests worldwide is estimated at All these activities directly or indirectly involve forests.
The plant and tree roots also break the soils in finer particles and encourage water infiltration into the soil.
