What is the biggest effect of overpopulation?
The most drastic impact so far is food shortages, with one billion people classified as ‘undernourished’ by the World Health Organization (WHO) in 2009, and nearly a billion undernourished in each of 2007, 2008, and 2011. 3 billion people in the world today struggle to survive on US$2/day, and food prices are rising. The second and thirds impacts of overpopulation are Peak Oil and Climate Change. Some will argue that climate change is not man made, but it is indeed happening and causing crop failures. The world is producing less oil today than it did last year, and this trend will continue. Both peak oil and climate change result in less food to feed the world, peak oil because food depends on mechanized farm machinery and transport.
