Deforestation has several negative effects on wildlife, including loss of habitat which can lead to displacement, increased competition for resources, and reduced population sizes. It can also disrupt food chains and ecosystems, leading to a loss of biodiversity and extinction of certain species. Additionally, deforestation can expose wildlife to poaching, increase their vulnerability to predators, and limit their ability to find food and shelter. Overall, deforestation has a significant impact on wildlife populations and ecosystems.
