Evidence also suggests that humans are liable to increase CO2 emissions from the soil into the atmosphere with new land-use practices.
The researchers said that wild boars extract about five million metric tons of carbon dioxide from the soil while searching for food. This equates to over 1.1 million cars.
In order to accurately determine the climate damage caused by wild pigs on five continents of the planet, scientists used predictive models with advanced mapping methods.

“Wild pigs are just like tractors plowing through fields, turning over soil to find food,” experts say, highlighting the proliferation of wild boars.
Soil contains nearly three times as much carbon as the Earth’s atmosphere. Therefore, all the CO2 extracted from it can accelerate climate change at times.

Recall that 17% of greenhouse gases in the European Union are emitted by animals, which is several times higher than the amount of CO2 emitted by cars. More than 500 million tons of carbon dioxide are produced annually on farms.
