Deforestation
I am doing my project on deforestation, and I learned that almost all off the United States and 75% of Canada were forests, and now there are barely any left. Almost half of all the forests in the world are gone, and what’s left is dropping fast. Deforestation is ruining the forest, and is also raising the Co2 levels in the atmosphere. Deforestation ruins the forest now, and for generations to come, the forests never grow the same again. They grow back with different species, and typically grow smaller. The cutting of trees also leads to less Biodiversity. “Many Different Species” The cutting of trees destroys animal’s homes, and many rain forest dwellers have very sensitive habitat and cannot handle change. Biodiversity is important for the circle of life, because if one spices of animal dies, there will be many more just like it to take its place. If there are very few species, if one animal goes extinct, it may wipeout a whole other species.
The rainforest not only keeps plants and animals alive, but also humans. The indigenous people who live in the forest need the forest to survive. They use the forest as their homes, and also use the forest for food, and water. These people take good care of the forest because it is so important to their survival. These people understand how to utilize the forest with out killing it, and what cycles work best for harvesting. Some people don’t preserve the forest, and just use the forest as a means to make money. These people cut down trees for rare woods, Plant crops, and raise cattle on the land. They don’t understand that the rainforest is a delicate place. When farmers are planting crop they use only one type of crop. By doing this they are sucking all of the nutrients out of the soil. After about two years all of the nutrients are gone and the farmers move on to another patch of rain forest to destroy. People also use the forest for cattle and plant savanna grass for the cows to eat. Once the grass is eaten and all the nutrients are taken out, it is hard for life to live there any more.
Even recently the rain forest is being cut down. From 2000 to 2006 150,000 square kilometers were deforested. One of the main contributors to this is beef. Cows have a hard time living in the forest; the farmers cut down the trees and allow the cattle to graze freely. From 1990 to 2001 Europe’s beef imports from Brazil rose 34%, and created a first time growth in Brazilian cattle production. This led to many more people getting into the cattle business, and clearing more land for cattle. With ever growing cow population the forests are struggling, and with soybean planting, and illegal logging, no one knows how long we can hold on to the rain forest.
