Wild pigs have impact on climate equivalent to a million cars, researchers say

• Source:  1 NEWS Researchers in Australia and New Zealand say wild pigs across the world are having the same impact on the climate as a million cars. Feral pigs in the Northern Territory Source: istock.com Their research, recently published in Global Change Biology, says by uprooting carbon trapped in soil, wild pigs are releasing about 4.9 million metric tonnes of carbon dioxide per year. This is equivalent to 1.1 million cars. The researchers from the University of Queensland and University of Canterbury used models of wild pig population density, soil damage, and their effect on soil carbon emissions to reach their findings. 

The climate impact of wild pigs greater than a million cars

Share By uprooting carbon trapped in soil, wild pigs are releasing around 4.9 million metric tonnes of carbon dioxide annually across the globe, the equivalent of 1.1 million cars. An international team led by researchers from The University of Queensland and The University of Canterbury have used predictive population models, coupled with advanced mapping techniques to pinpoint the climate damage wild pigs are causing across five continents. UQ’s Dr Christopher O’Bryan said the globe’s ever-expanding population of feral pigs could be a significant threat to the climate. “Wild pigs are just like tractors ploughing through fields, turning over soil to find food,” Dr O’Bryan said.
