Exact excerpt

Limits to Growth predicted that at 1972 rates of growth the world would run out of gold by 1981, mercury by 1985, tin by 1987, zinc by 1990, petroleum by 1992, copper, lead and natural gas by 1993. The USGS reports that 50 years later current proved reserves of copper stand at 880 million tons, gold at 54,000 tons, tin at 4.9 million tons, zinc at 250 million tons, and lead at 90 million tons. The proven reserves of nonrenewable resources have not been depleted over the past 50 years, they have instead increased substantially.
