The ever-growing human consumption and population is the biggest cause of forest destruction due to the vast amounts of resources, products, services we take from it. Direct human causes of deforestation include logging, agriculture, cattle ranching, mining, oil extraction and dam-building.
Why is farming a threat to the rainforest?
Soil erosion – the soils of the Amazon forest are not fertile and are quickly exhausted once the forest is cleared. The farmers now artificially fertilise the soil when in the past the nutrient cycle would have done this naturally. In addition, the lack of forest cover means that soils are exposed to the rainfall.

In fact, ranching can be a key cause of desertification. Livestock ranching also contributes to air and water pollution.
What are the disadvantages of ranching?
Livestock ranching also contributes to air and water pollution. Runoff from ranches can include manure, antibiotics and hormones given to the animals, as well as fertilizers and pesticides. Chemicals from tanneries that treat animal hides can also seep into water. Ranching is also a major contributor to global warming.
