How much forest is cut down for agriculture?
Rainforests across the world are in great danger. Food and Agriculture Organization’s 2016 State of the Forests report revealed that 7 million hectares of forest are lost annually while agricultural land expands by 6 million.
Does agriculture affect rainforest?
Agricultural use of some rainforest land proves to be a failure because of the nutrient-deficient, acidic soils of these forests. Burning releases nutrients locked up in vegetation and produces a layer of nutrient-rich material above the otherwise poor soil.
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.
What is the biggest problem in the Amazon rainforest?
Cattle ranching is the leading cause of deforestation in the Amazon rainforest. In Brazil, this has been the case since at least the 1970s: government figures attributed 38 percent of deforestation from 1966-1975 to large-scale cattle ranching.

Why did the Amazon fire start?
Scientists and environmentalists say the reason the Amazon is on fire is because farmers are deliberately starting blazes in their efforts to clear land for crops or livestock. One researcher estimated that humans start 99% of all Amazon rainforest fires. Such fires are a major cause of deforestation in the Amazon.
Can the Amazon rainforest grow back?
Much of the Amazon’s secondary forests are born from extensive pasture land that has lost its commercial productivity. So as the rainforest soil loses its nutrients, many farmers move on to new areas, abandoning large areas of former pasture that then regrow naturally.
Why did they burn the Amazon rainforest?
Fires normally occur around the dry season as slash-and-burn methods are used to clear the forest to make way for agriculture, livestock, logging, and mining, leading to deforestation of the Amazon rainforest.
