Shouldn carrying capacity be viewed in global terms?
Carrying Capacity is the maximum population that can be sustained in an area without diminishing the ability to support the same number in the future. Thus, carrying capacity is relevant both on a planetary, as well as national level. If we in the United States, by importing oil and other resources, expand our numbers beyond our own capacity to support those numbers, we do so at the expense of the carrying capacity of the rest of the world.
