Limits to Consumption
If we continue consuming non-renewable natural resources as we have, we could complete our decimation of other species by the end of the next decade, and risk extinction ourselves by mid-century.
Continuing our increase in consumption, we would need new technologies to live without Nature's free services, and then, gradually, devour our entire planet and others. Natural laws prohibit us from sustaining positive exponential growth for very long.
ABOVE: If, starting at the end of 2007, the ecological footprint changes exponentially, humanity will reach a set of successive transitions to keep our population growing. The range of times for each transition is bracketed by a "low" and "high" estimate.
