How do humans affect plants and animals?

Human activity often changes or destroys the habitats that plants and animals need to survive. Because human population is growing so fast resulting in growing demands. Animals and plants are disappearing 1000 times faster than they have in the past 65 million years. Plants provide us food, materials for shelter, fuel to warm us and replenish oxygen in the air. Plants provide food for animals and habitat for wildlife. Animals both large and small are a critical component to our environment. Domesticated animals, such as livestock, provide us food, fiber and leather.
