 Amazon rainforests are being rapidly destroyed due to a variety of factors, including large-scale agriculture, improved market access, and high agricultural prices. These factors are often driven by government policies, such as infrastructure expansion, mining, and oil extraction. Additionally, technological, socio-cultural, and institutional factors play a role in accelerating deforestation. Public and private policies have been shown to be effective at reducing deforestation, with protected areas and public policies standing out as particularly successful. However, more research is needed into other underlying causes and policies, such as frontier age, land tenure, and policy interactions. This article was authored by Alain Hangley, Samuel A.
