Mars Incorporated, the maker of Snickers, Skittles, (INAUDIBLE), Lifesavers, Five Gum, says from here on out, it`s only going to use palm oil that`s obtained without hurting the environment. One way to do that is by planting oil palm trees and making sure that much of the palm oil they produce goes to good use. But there`s another way to get the ingredient. One that`s more harmful for the environment, one that involves deforestation. What does that matter? Deforestation is the practice of cutting down forests for various different reasons, but it`s fundamentally cutting down trees and living behind a vast open wasteland. Deforestation is most common in countries like Brazil, Indonesia and Mexico, Papua New Guinea, and Russia. The main causes of deforestation can be classified into three categories. Basically, industrial uses, chopping down the forest to build factories or to build residential areas. The second one is agriculture. So cutting down forest in order to grow, for example palm oil plantations. Agricultural deforestation can also be caused by non-food crops, for example, paper plantations. And the third cause is life stock. So, in many places, for example, in Brazil, deforestation is caused by farmers clearing the land to create pasture land for cows. Deforestation can happen on a lot of different scales. It can be anything from illegal squatting, a dozen folks in local village using small rudimentary chainsaws and cutting down the trees and then, of course, on the other end of the spectrum is massive industrial scale. Deforestation, when they bring in lots of heavy machinery for advanced technology, and they can go in and clear forest in a very short amount of time. Deforestation affects the environment in two main ways: trees, of course, absorb carbon dioxide and as human beings put more and more carbon dioxide into the atmosphere, the more trees we cut down, the more we hinder the ability of the planet to balance how much carbon is in the atmosphere. But another impact of chopping down forests is, of course, reducing the habitat for animals to live in. Every year over thousand different species go extinct around the world. That is a conservative estimate, and a big chunk of that happens because of deforestation.
