We Must Save the Rainforests

Rainforests, should we cut them down or not? Probably one of the biggest questions the world has to overcome. Sure, rainforests supply us with a lot of resources and we could surely not live without cutting some of them down, but should we be cutting them down at the rate we are? To be exact, the statistic estimates 1.5 acres of natural rainforests are being destroyed every second. While this practise supplies us with resources like timber for furniture, it also reduces the amount of oxygen supply.

Rainforests once covered 14% of the worlds land surface, however now it only covers a mere 6%. It is estimated that all rainforests could be consumed in less than 40 years. Trees are becoming more needed and used everyday. We need them cut down for many reasons such as paper and timber, while also needing them ‘untouched’ for other reasons like oxygen, we have to ask ourselves, which is more important? At the current rate, most of the rainforests are being cut down for resources like paper and timber, but less importance is being placed on main resources like oxygen.

Simply speaking, rainforests are basically the foundation of the earth. The most important role that rainforests play is ‘the lungs of the earth’. This is extremely vital to the earth’s survival as the trees and plants absorb carbon dioxide which they use to help grow and let out oxygen which we need to live. This system is known as the carbon-oxygen cycle and with numbers of rainforests declining, it is highly threatened. The largest rainforest in the world, the Amazon, alone is known to produce half of the world’s oxygen. A break down in the carbon-oxygen cycle means that we will not only have less oxygen, but an increase in carbon dioxide which eventually leads to global warming. This occurs as carbon dioxide traps heat which actually keeps the earth warm, with the right amount of carbon dioxide that is. This is called the greenhouse effect and occurs naturally however due to decreasing number of trees, there is more carbon dioxide than needed which traps extra heat making the earth hotter than needed, this is known as global warming which also causes a rise in sea level.

The world’s climate is kept stable and suitable to live in, mainly by rainforests, in a number of ways. They are often known as ‘climate controllers’. They keep the planet cool, as they absorb much of the suns heat, instead of reflecting it back into the atmosphere.
