Humans and the Natural Environment
No other species in Earth's history has been able to disregard the natural laws that govern population size quite like humans have. And as a result we have experienced an unfathomable population explosion: a nearly 7-fold increase in three centuries and from 3 billion to 6.6 billion in just 45 years (1961 to 2006).
