Deforestation is the permanent removal of forests, mainly due to human activity like agriculture, logging, and urbanization. Tropical rainforests are particularly threatened, as 17% of the Amazon has been lost in the past 50 years mostly to cattle ranching. Deforestation causes environmental problems like changes to atmospheric conditions, hydrological cycles, soil health, and loss of biodiversity. The conclusion is that deforestation poses serious risks and everyone must make an effort to reduce forest clearing and burning to prevent further damage.
