Most contemporary estimates for the carrying capacity of the Earth under existing conditions are between 4 billion and 9 billion.
Has Earth reached its carrying capacity?
Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people. [How Do You Count 7 Billion People?] One such scientist, the eminent Harvard University sociobiologist Edward O. Wilson, bases his estimate on calculations of the Earth’s available resources.
How long can Earth sustain human life?
In 300 million years or less, it may become very inhospitable for life to continue to exist on the land, and if we leave it alone, evolution may encourage life to return to the sea where the climate will be a bit more moderate.

Will the human population eventually outgrow the earth’s ability to sustain it?
Understanding Carrying Capacity Human population, now over 7 billion, cannot continue to grow indefinitely. There are limits to the life-sustaining resources earth can provide us. … Carrying capacity is the maximum number of a species an environment can support indefinitely.
How many humans have there ever been?
