@Wetrix because it is impossible for a population to exceed the capacity for it to be supported by available resources. If there is only enough to support 5 people, he can there be 6 or 7? There cannot. As the size of a population approaches a resource limit you'll see infant mortality rise, yet we see infant mortality lowering. If we were even close to earths capacity to support us our population would not be exploding by ~15% - that's 1 billion people - every ~13 years.
