Why is the population growth of the human species different from that of all other organisms?

Humans alter our environment to survive and fight the natural limiting factors in the environment.  While most species have to go to water, we have inventions that bring water to us.  We also have modern medicine to fight disease, thus removing another limiting factor from our species.  We continue to procreate at a natural (and supernatural rate with things like artificial insemination and fertility therapies), then we die off at an extremely low rate due to inventions, and the use of science and intellect in our survival.
