What are the three biggest threats to rainforest?

1) Deforestation: The single biggest threat to rainforests is deforestation. This is the clearing of rainforest land for other uses, such as agriculture, logging, mining, and urbanization. Deforestation is a major contributor to climate change, as it releases carbon dioxide and other greenhouse gases into the atmosphere, while also reducing the amount of forest available to absorb carbon dioxide.

2) Climate Change: Climate change is another major threat to rainforests. As the Earth's climate warms, rainforests are becoming drier and more susceptible to wildfires. This is also causing the ranges of some rainforest species to shift, as they try to find more suitable climates.

3) Over-exploitation: Over-exploitation of rainforest resources is another major threat. This includes the over-harvesting of timber, wildlife, and other forest products. Over-exploitation can lead to the depletion of these resources and the disruption of rainforest ecosystems.
