The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Natural vegetation and wildlife maintain the balance of our earth in that vegetation, woods, plants, and flowers provide the oxygen humans need to live on planet earth. Animals provide food and clothes for humans. The wildlife eats the plants, vegetation, and fruits from Mother Earth to keep a balance in the planet's ecosystem so there is always an equilibrium.
This means that wildlife maintains the ecosystem of different regions of the world. The wildlife makes possible the chain of food in nature to te keep the ecosystem in balance.
That is why it is very important that government agencies such as the Environmental Protection Agency (EPA) provide protection programs to take care of the environment and minimize pollution.
