Deforestation in 150 words please
Answers
Answer:
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.
Answer:
We live in a country where the temperatures are comparatively higher. In these tropical countries, the tree plays a significant role in bringing rainfall. Trees take care of the water cycle. They initiate precipitation and cloud formation. Trees can also be beneficial in case of flood protection. The mangrove of Sundarbans protects the area from devastating floods. Flood still occurs in these areas regularly, but the impact is controlled due to the mangroves. If we keep cutting den trees haphazardly and randomly, the soil structure will see massive changes. Soil erosion is an authentic problem. It degrades the quality of soil that is being used by the farmers for agriculture. Trees provide fresh oxygen to the people. Trees are also the shelter for various birds and animals. Most nocturnal birds and migratory birds find their homes in the trees. The effects of deforestation have made millions of birds, close their habitat.
