Fish, trees, and animals are important wildlife resources that we depend on for survival. Fish are a main source of food for many of the people in the world. Trees have been used to build and heat homes, make paper, and provide food for centuries. Humans hunt land animals such as deer, fox, antelope, and buffalo for food and other products. What can we do to protect wildlife resources so they will be around for future generations? nothing-wildlife resources are renewable and will eventually replenish themselves harvest fast-growing trees, impose fishing limits, and impose laws to prevent poaching and illegal hunting not use wildlife resources-they are nonrenewable and cannot be replaced not allowing fish farming, selected harvesting of younger trees, and laws that do not put a limit on hunting

harvest fast-growing trees, impose fishing limits, and impose laws to prevent poaching and illegal hunting
