Question

What is meant by capacity of earth

Answer 1

Carrying capacity is not a fixed number. Estimates put Earth's carrying capacity at anywhere between 2 billion and 40 billion people [source: McConeghy]. It varies with a wide range of factors, most of them fitting under the umbrella of "lifestyle." If humans were still in the hunter-gatherer mode, Earth would have reached its capacity at about 100 million people [source: ThinkQuest]. With humans producing food and living in high-rise buildings, that number increases significantly [source: ThinkQuest].

As of 2008, there were about 6.7 billion people living on this planet [source: Sachs]. A good way to understand the flexibility of Earth's carrying capacity is to look at the difference between the projected capacities of 2 billion and 40 billion.
