The consequences of deforestation
Deforestation is one of the causes of environmental pollution, the phenomenon of the earth warming, famine, floods, accidents forest elephants left the village to kill people, out property damage ... as well as the destruction of forest products under the forest canopy caused ecological imbalance serious, leading to erratic climate change, floods, flash floods, landslides and generated much diseases.
Worldwide, deforestation causing damage to 45 billion / year. According to the latest statistics of the Ministry of Environment America, every year on average in the world has about 33 million hectares of forests are destroyed for many different purposes has created more than 1.5 billion tons of CO2 into the environment, accounting for up to 20% of man-made emissions of greenhouse effect causing global warming temperatures.
it is estimated to deforestation today, 2050, up to two billion people, or 20% of the world population will dehydration. Most people suffer from water shortages live in developing countries. Besides food sources are also threatened by the risk of water used for irrigation becomes scarce.
The effects of deforestation upstream in VN
According to the latest report of the World Food Programme (FAO), VN is one of five countries most heavily affected from natural disasters, especially storms and flooding rain. Rainstorm occurred in the territory VN increasing both the frequency and the danger, is becoming the real threat to the lives of people and the development of the economy.
In addition to these causes as geographical features, climate change causes flooding situation in VN is becoming increasingly fierce, there is a direct cause of the people. Watershed Deforestation for logging, agricultural development, hydropower ... as vegetation in the basin declining ability resistance leads to poor flow, flood focus faster.
In mid-October last, many provinces in the central region was held for several consecutive days of rain caused floods and heavy losses of life and property. This was the first flood functional departments assessed as a percentage of the new year and concluded, was due to deforestation upstream. When headwater forests are cut down, the intensity of the floods come quickly, making the water level rise rapidly. Forest trees to prevent floods, erratic disaster. When floodwaters rise, trees blocks the roots will absorb water and flood waters somewhat. There are trees, water power stronger support, windbreak trees and weaken the power in the storm passing through the area. According to scientists, the many watershed forests and protective forests in the central provinces were razed to make room for hydropower are losing the ability to regulate water when heavy rains upstream, this is a major cause causing severe flooding more days.
our country is actively implementing two major programs that the national target Programme to respond to climate change and national Programme for disaster Prevention. Central objective of this program that is growing and forest protection. From model implemented until results are still a distant and unknown to ever new narrow this gap, to avoid danger to themselves and future generations.
