What is deforestation?

Deforestation is when forest are destroyed by cutting and not replanted. Sometimes deforestation happens when people change the land into farms, ranches and cities

A lot of deforestation is caused by the removal of all the trees from a forest for wood or fuel. Without the forest, the habitats of the animals are lost and many animals die.


Deforestation is a very serious problem nowadays, it doesn’t only cause global warming but will destroy home’s of a lot of animals. We human should think about our next generation and start saving the forest and the world.

Causes

We can identify the following causes of deforestation.

Wood logging is the cutting down trees for the purpose of production of paper, furniture, flooring, toothpick, etc.


Agriculture expansion -

Because of the growing population, there is more need for food and crops. Therefore more agriculture area is needed, and trees are cut down to create more available agriculture land.


Urbanisation- The growing population causes the need for more construction sides, therefore trees will be chopped for supplies.


Forest fires - One of the main causes is human act, such as barbecuing and dispose cigarette butts. Every year, there are forest fires which destroys large area of forest all over the world.

Effects

There are a lot of negative effects of deforestations. Seventy percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes.

  • Severe greenhouse gas emission and global warming

Forest is a major source of oxygen in the world and absorbs an extensive amount of carbon dioxide. Deforestation will greatly increase the amount of carbon dioxide in the atmosphere, which leads to global warming.

  • Species extinction

Forest is the habitat for a huge proportion of animals and plants in the world. Deforestation means destruction of their home, source of food and water to them.


  • Flood

Trees have an important role during raining because their roots can absorb a lot of water. Deforestations reduce the amount of trees so that when there is a rain trees can no longer help to absorb water. As a result the chance of flooding increases.


  • Soil erosion

Roots of trees could anchor the soil. Without trees, the soil is free to wash away, which can lead to vegetation growth problems Moreover, soil, being washed away, can become silt in lakes, streams and other water sources. This can decrease local water quality and contribute to poor health in populations in the area.

Possible solution

  • government limit the number of trees companies cut down

if the government is willing to do something about banding the companies from cutting down a large amount of trees.

  • grow trees while cutting it.

Nowadays in our daily life we need to use a lot of paper, for example in the office and school, and we need to cut down a lot of trees to make paper. If workers need to cut down trees they should plant more trees when they cut off some so that we can keep the forest living.

  • try to use e-resources

i believe everyone has a laptop/ smartphone these days, in our daily life we need to use a lot of paper and to avoid this we can use e-resources instead. Technology are very advanced these days, we can use email and a lot other apps or websites to replace from using papers.
