Concerns for an Increase of People

While the Earth can only support a certain amount of people, the issue is not so much about space as it is a matter of resources like food and water.  According to David Satterthwaite, the concern is about the "number of consumers and the scale and nature of their consumption."  Thus, the human population can generally meet its basic needs as it grows in regards to environmental space, however not at the scale of consumption that some lifestyles and cultures currently support.

It is important to realize that while data is collected on population growth, it is difficult for even sustainability professionals to understand what will happen when our population reaches, ten or fifteen billion people on a global scale. While we can conclude that, currently, overpopulation is a myth, the focus would be primarily on distribution of people to various spaces on Earth.

Regardless, birth rates have been falling around the world which may slow down population growth in the future.
