The document discusses deforestation, particularly in Brazil's Amazon Rainforest. It notes that deforestation is driven by activities like agriculture, logging, and cattle ranching. This has negative environmental impacts such as loss of biodiversity, soil erosion, and disruption of the water cycle. Brazil has the highest annual deforestation rate of any country since 1990. Deforestation threatens ecosystems like the Atlantic Forest in Brazil and reduces habitats for plants and animals.
