The word deforestation is used to describe the process of cutting down and burning the trees in forest and woodland and converting the land to other use. It also means that the nature of trees have changed, such as replacing slow growing native trees with fast growing woods which means that the precious eco-system of the forest into less bio-diverse ecosystems such as pasture, cropland, plantations and removal of rainforest. Forests still cover about 30 percent of the Earth’s surface, but each year about 13 million hecters of forest (approximately 78,000square miles) are converted to agricultural land or cleared for other purposes.
There are two key issues that surround deforestation. Trees absorb CO2, helping to reduce the amount of carbon in the atmosphere. Carbon is one of the key causes of global warming and reducing these gases will help to slow and stop the greenouse effect.
The other issue is that trees are often cleared and burned. The wood from the trees is simply destroyed and not put to any positive use. The burning of the wood releases carbon into the atmosphere, and releasing harmful greenhouse gases, yet reducing the number of trees that would have helped to remove this from the atmosphere. It also contributes to global warming tropical deforestation for about 20 percent of all greenhouse gases and has an important impact on the global economy.
Rainforest Action Network (RAN) campaigns for the forests, their inhabitants and the natural systems that sustain life by transforming the global marketplace through education, grassroots organizing, and non-violent direct action. RAN estimates that 90 percent of the rainforest is already gone.
Causes of Deforestation.
Some of the most common causes of deforestation are globalization, urbanization, overpopulation and climate. Trees are being cut down for construction purpose, lands are cleared for growing crops and trees are also used as firewood.
Globalization in many countries has lead to deforestation as many industries and factories are build which emit carbon dioxide which affect the trees and forest. India and china are a big example. China being a big market for producing and supplying many products in various parts of the world for which trees and forest are used to produce product.
Urbanization also leads to deforestation as the country develops the cutting down of trees for the use of building materials, furniture, paper products and material used for highway and roads. Forests are also cleared in order to accommodate expanding urban areas. They are cut down in order to create land for grazing cattle and for growing crops. Trees are also cut down in developing countries to be used as firewood or turned into charcoal, which are used for cooking and heating purposes.
Overpopulation also causes an increase in population also means an increase in produce consumption for which the trees are being destroyed. The basic needs being shelter and food are given with the help of forests for which an optimum amount of consumption and production is needed. Overpopulation in countries like China and India are a result where deforestation rate is higher than comparative countries.
Climate is also one factor for deforestation mainly acid rain. Climate not only affect the people but also trees, roads and small plants. Trees are also harmed by acid rain. Scientists say that acid rain damages the waxy outer coating that protects the leaves. When this happens, it allows the acid to seep into the tree. Instead of water changing from a liquid to a gas inside the leaves, gas is taking the place of the water. This prevents the plant from taking in carbon dioxide to perform photosynthesis, and the plant eventually dies. Global warming is another factor as the temperature increases than the average temperature which affects the plants growth or soil growth.
Effects of Deforestation.
The effects of deforestation are mainly causing our environment worse, such as soil erosion, biodiversity impacts and social effects.
Answer:
The main purpose of deforestation is to increase the land area. Also, this land area is to set up new industries. And, this all is because of the increase in population. As the population increases the demand for products also increase. So rich businessmen set up these industries to increase profit.
Harmful Effects of Deforestation
There are many harmful effects of deforestation. Some of them are below:
Soil erosion: Soil erosion is the elimination of the upper layer of the soil. It takes place when there is removing of trees that bind the soil. As a result wind and water carries away the top layer of the soil.
Moreover, disasters like landslides take place because of this. Furthermore, soil erosion is responsible for various floods. As trees are not present to stop the waters from heavy rainfall’s gush directly to the plains. This results in damaging of colonies where people are living.
Global Warming: Global warming is the main cause of the change in our environment. These seasons are now getting delayed. Moreover, there is an imbalance in their ratios. The temperatures are reaching its extreme points. This year it was 50 degrees in the plains, which is most of all. Furthermore, the glaciers in the Himalayan ranges are melting.
As a result, floods are affecting the hilly regions of our country and the people living there. Moreover, the ratio of water suitable for drinking is also decreasing.
Impact on the water cycle: Since through transpiration, trees release soil water into the environment. Thus cutting of them is decreasing the rate of water in the atmosphere. So clouds are not getting formed. As a result, the agricultural grounds are not receiving proper rainfall. Therefore it is indirectly affecting humans only.
A great threat to wildlife: Deforestation is affecting wildlife as well. Many animals like Dodo, Sabre-toothed Cat, Tasmanian Tiger are already extinct. Furthermore, some animals are on the verge of extinction. That’s because they have lost habitat or their place of living. This is one of the major issues for wildlife protectors.
