Tag: damaging the forests

Destroying a forest has many negative effects on the environment. Seventy percent of earth's terrestrial animals and plants live in forests. The most adverse impact is the loss of habitat for millions of species leading to disturbance in the food chain that is an important component of the ecosystem. Thus the correct answer is option A.

Cutting of trees or clearing the forest is called as deforestation. Deforestation not only affects the land from which it is cleared but it also affects the environment. Trees are very important for the environment because they help in reducing pollution by releasing more oxygen. They protect the environment in many ways and hence, cutting of the tree is harmful and affects the environment.

Reforestation is restocking of the destroyed forest by planting new trees. We should plant at least as many trees as we cut. Reforestation can take place naturally also.

Deforestation is the process of removal or the cutting down of the trees. The absence of the trees results in an increase in the concentration of carbon dioxide which causes global warming. The roots of the plants help in holding the soil and deforestation causes soil erosion from the upper layer of the soil. The plants take up the carbon dioxide from the air for photosynthesis. When there are no trees, there is increase in the level of carbon dioxide.

Deforestation is removal, decrease or deterioration of forest cover of an area. It causes shrinkage of fuelwood, reduced timber supply, change in climate, flash floods, soil erosion, siltation, cyclones, drought, desertification, reduced rainfall and destruction of habitat. Thus, the correct answer is option D.

Drought is the condition of shortage of water which affects all life forms. Flood is the condition of the overflow of water on land that can submerged plants, human-made articles and thinning of the ozone layer increases the global warming and climate change which affects the flora and fauna. All these conditions can harm the organisms and their habitat and thus, can threat to the biodiversity.

Deforestation is the depletion / destruction of forest resources. Its main cause is the explosion of human and livestock population with the increased demand of the basic needs. The major effect of deforestation is the loss of precious wildlife, rare species of flora and fauna due to loss of habitat, soil erosion, accentuated floods, drought, pollution and increased level of carbon dioxide.

Deforestation is the permanent destruction of forests in order to make the land available for other uses. Deforestation has many negative effects on the environment. The most dramatic impact is a loss of habitat for millions of species. Seventy percent of Earth's land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes. Deforestation also drives climate change. Since, trees purify air by absorbing carbon dioxide from atmosphere, loss of trees would result into increase in level of carbon dioxide.
