NEGATIVE EFFECTS OF HUMAN CHANGES IN THE AMAZON RAINFOREST

Deforestation:

Human activity and development in the tropical rainforest has led to a decrease in habitats for many of the earth's species. Environmentalists estimate that we no longer have 137 plants, animals and insect species due to rainforest deforestation.

This continual action is due to the industries of mining, lumber, and agriculture. The productive development in these areas are polluting tropical rainforests, reducing the habitat of many species, and producing loud and disturbing noises from the machinery.

More and more of the natural vegetation is being replaced with farmland because the fertility of the soil consumes only a few years after it was originally cleared. Rainforests once covered roughly 14% of the earths land surface; now they cover approximately 6%. The issue and effects of deforestation is substantially affecting the most biologically diverse biome in the world.

Overexploitation: Human activity and development in the tropical rainforest has led to massive amounts of rainforest land being transformed into other human uses such as mining or agriculture. Overexploitation of the rainforests natural resources is a highly damaging impact that humans have on the rainforest.

Great amounts of trees are cut down in the rainforest which are used for the timber industry, this cutting down of the trees causes a massive drop in the habitat of the forest’s structures and the machinery used to complete this process provide a massive source of pollution and habitat destruction.

Approximately 80% of the rainforests nutrients comes from trees and plants. That leaves 20% of the nutrients in the soil. When trees are over exploited conditions change very quickly, the soil dries up and causes erosion. Poaching and hunting are a major issue in the tropical rainforest, exotic creatures are being over hunted causing their populations to go into the danger zones and on the brink of extinction.

Furthermore, the rainforest is being used up at an extrodinary rate for mining purposes: oil, gold and iron ore are being mined at a immensive rate.
