Garrett Hardin

Garrett James Hardin (April 21, 1915 – September 14, 2003) was an American ecologist and philosopher who warned of the dangers of overpopulation. His exposition of the tragedy of the commons, in a famous 1968 paper in Science, called attention to "the damage that innocent actions by individuals can inflict on the environment". He is also known for Hardin's First Law of Human Ecology: "We can never do merely one thing. Any intrusion into nature has numerous effects, many of which are unpredictable." **Source**: <a href="https://en.wikipedia.org/wiki/Garrett_Hardin">Garrett Hardin</a> on Wikipedia (Wikipedia contributors, <a href="https://en.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_Attribution-ShareAlike_3.0_Unported_License">CC BY-SA 3.0</a>).
