How have humans changed the environment and what are the consequences of these changes ?

Explanation:

Humans have changed the environment by evolving and using natural resources, with the natural resources slowly dwindling down is will affect the earth greatly. The earth won't be able to regenerate the resources fast enough for us to use them.  The consequences are that we will burn up the earths valuables and end up stripping the earth of primary resources, making the earth weaken and have nothing to provide animals or other living creatures. Humans have heated up the environment, cut down many forests, made many species extinct and already stripped many key resources.
