Deforestation is reshaping forest ecosystems and raising extinction pressure for species worldwide. These effects hit hardest in the tropics, where clearing can push 18–30% of species into higher risk and where agriculture, cattle ranching, logging, and commodity expansion drive much of the loss. Across the page, you’ll learn how forest cover declines are measured, where deforestation is occurring, and how impacts connect to climate and biodiversity.
