What Are The Causes Of Ecological Change In The Amazon Rainforest?

Earth, the third planet from the Sun, a paradise in the middle of the vast emptiness of space. This planet is home to many different species of life. Each one of those species thrive in its own ecological system. However, those locations are slowly starting to disappear. The Amazon Rainforest, one of the most biologically diverse regions on the planet has lost 20 percent of its total land area (Wallace). This, is having a disastrous effect on the ecology of the local area, and the planet as a whole. There other events though can cause such a dramatic change in the world ecology The causes of ecological change are many and their effects are having a disastrous impact on the world. Ecology is the study of the interactions between lifeforms and their environment. It is a subfield of Earth Sciences. The field of Ecology had its beginnings in ancient Greece. The world ecology comes from the greek words “Oikos", which means “house”, and the word “Logos”, which means “the study

The causes for this are more than can be mentioned in a short essay. The principle enabling factors for ecological change are pollution, deforestation, and the extinction of native wildlife. All of those mentioned are due to human behavior. Pollutants are hazardous chemical or physical substances released in the air, water, or ground (Saier). Deforestation is also having a major effect on the ecology of the planet. Since the year 2000 the planet has lost 2.3 million square kilometers of forest land (Metcalfe). The extinction of native wildlife is also causing major change in the world. Scientist estimate there are 8.7 million species that live on Earth. The current extinction rate is 100 species per every million each year (Alford). With all these events happening at once its is no wonder there has been such a dramatic change in the world
