Chart of Human Population Growth by Region
Directly or indirectly, the human species already captures nearly 40% of the total biological productivity on land and 70% of the productivity of the marine environment — the "net primary productivity" of the planet — for its exclusive use. The rate of increase in human use is about 2% per year."
