Deforestation

DEFORESTATION


 

Deforestation is a common global issue which many areas of the world face as it is destroying the earth's ecosystems although there are many positive benefits. This topic has some controversy as there are arguments from both sides. I believe that this global issue should be looked into further as it is the cause of many problems.

The reduction in Earth's forest commenced at least 8,000 years ago, when humans began to clear land to allow for easier hunting of wild animals. Deforestation is caused by humans cutting down forests for reasons such as to produce flat land or for farming, mining, livestock grazing, and urban development. The main cause of deforestation is agriculture. Farming is responsible for 48% of deforestation, commercial agriculture is responsible for 32% of deforestation; logging is responsible for 14% of deforestation and fuel wood removals make up 5% of deforestation. With the current rate of deforestation in a hundred years the world's main source of wood, the rainforests could vanish.

Deforestation has led to the extinction of numerous populations of animals. More than half of the animal and plant species in the world live in tropical forests. Animals such as  three-toed sloths have become endangered because of humans cutting down trees. Many birds also rely on forests to make nests and hatch their young .Not only are we taking away animal homes but animals rely on trees as a food source whether they eat part of the trees or other species among them . The sloth is not the only animal affected by deforestation many other mammals, amphibians, insects and plants are endangered due to deforestation.

Deforestation is considered to be an important contributor to climate change and oxygen levels. Trees emit oxygen so the higher the deforestation level the less oxygen produced. When the trees are cut down the soil on the forest floor is not protected by the shade of the trees making the soil dried out and eventually turning forests to deserts.

Although there are many negative impacts people would argue it as not being an issue. People argue that it has many positive benefits. These could include benefits such as using trees to produce economic growth and development. It also allows countries to produce new jobs. It takes human labor to cut trees, ship them and to produce them into products. Others would also argue that it is good because it provides crucial resources like wood that can be used to build buildings and to make paper. Deforestation helps provide resources for many other countries that don't have forests by shipping them from countries that do.
I believe that deforestation is a serious issue that should be addressed urgently although there are many positive benefits. People should take action on this issue because this resource will take a large amount labor and many years to replace. The deforestation process is also very dangerous and has many risks involved therefore if humans decreased the amount of deforestation than there would be a lower accident rate.

If this issue is not addressed than forests will diminish and numerous animal populations will be lost. Also there will be a huge oxygen decrease and a large climate change. Most facts about deforestation are negative therefore the topic should be looked into further. If each person does there part by recycling and reusing resources maybe it could impact a bigger change and create a more green future with more luscious green forests.
