if everyone alive -- man, woman, child -- was given 1 acre of land each (1 acre = 0.005 sq. km), then 30 million sq. km of Earth's land would be
occupied. That's only 20% of the Earth's land! Also, keep in mind that 90% of humanity lives on only 5% of the Earth's land -- which,
including businesses and other urbanized land, averages out to be much less than 1 acre per person.

This is true, however it is irrelevant. The problem is not that there is not enough space, but not enough resources. Any growing population will
eventually reach the carrying capacity of it's habitat. Since humans have the unique ability to heavily alter their habitat, this puts us in a tough
spot. On one hand this is an integral part of all the modern things we enjoy today. On the other, it means the more we alter our habitat, the more we
disrupt the systems that keep this planet living. Therefore, the more humans grow, the more they disrupt the environment, and the greater the chance
of serious damage to our habitat becomes. The point is that world population cannot continue to grow at this rate, if at all. Just because the US road
system can theoretically fit some 1.3 billion cars, that doesn't mean we should. Even though we have space for 31 billion people to have an acre of
land a piece, the planet can't take that kind of impact. Imagine all the pollution those people will create, the energy they consume(and the
pollution of the facilities that produce that energy), the goods they desire(and the pollution of the factories that produce those goods). They all
also need food, water and a hospitable environment, which we depend on the Earth for.
The more we grow, the more we choke off our supply
line.
Unless we can exist without terribly disrupting the environment, we must stop our growth. But, realistically speaking, this isn't
going to happen any time soon, if at all. It is foolish to think otherwise. It is possible, but highly unprobable. The way people think and what they
believe limit things like this. The people in the best position to do something about it are the least interested. So then, humanity will run into a
metaphorical wall. I don't know enough to say what will happen when it does, but I know enough to see the wall.
