What does deforestation do to our World?

Deforestation is awful. It’s the only way to put it. What good does it do? Ok it makes room for crops for all of the starving people on Earth. Ok it makes room for housing for everyone. Ok the wood can be used for countless products. But what are we really achieving here? Nothing is the answer to that.

Animals that live within the wonderful forests, lose their source of food when the trees are chopped down. This means that while the humans of Earth are provided with food, the animals lose their food source, and so they starve instead. This leads to the extinction of many animals every year. It is important to create a balance, between the land which is destined for animals, and that which is for humans. Animals should be given their fair share of the Earth, after all, they are just as important as we are.

Another issue with the removal of the forests is that they provide a habitat. If this habitat is removed, then the animals will have nowhere to go, and they will end up competing for less space, and less nutrients. This will lead to too much competition, and eventually some of the animals will not be able to survive.

This is a particular problem in the rainforest, which are home to over 50% of the species of Earth. We remove much of the rainforest every year, and with it we lose tens of thousands of species. Only 7% of the land is actually rainforest, and every year this gets smaller and smaller. With so many species living in the rainforest, it is important that we try to conserve as much of the forest as possible.

When the animals become extinct, it reduces the species diversity of the area. The species diversity is the number of species and the number of organisms within those species of one particular area. Forests, and in particular rainforests, have an extremely high species diversity. However, at the current rate of deforestation, the species diversity is rapidly decreasing.
