Deforestation has detrimental effects on wildlife, as it destroys natural habitats and disrupts ecosystems. Some of the effects of deforestation on wildlife include loss of biodiversity, displacement of species, increased competition for resources, and reduced food sources. Additionally, deforestation can lead to fragmentation of habitats, making it difficult for wildlife to find suitable areas to live and reproduce. Overall, deforestation has a significant negative impact on wildlife populations around the world.
