This can have a significant impact on the many species that depend on forests for their survival. ii.Urbanization: As human populations continue to grow, natural habitats are destroyed to make way for cities and towns. This can result in a loss of habitat for many species, making it difficult for them to survive. iii.Agriculture: As agriculture expands, natural habitats are cleared to make way for crops and livestock. This can result in a loss of habitat for many species, as well as soil erosion and water ...
