Scientists around the world are making strides in reducing methane emissions from belching livestock by developing probiotic supplements, breeding animals that emit less, and planting trees in pastures to absorb greenhouse gasses.

From New Zealand to the United States and Kenya to Colombia, scientists are on a mission to fight global warming by making livestock less gassy.

Livestock are responsible for about 14.5 percent of global greenhouse gas emissions, according to the United Nations’ Food and Agriculture Organization (FAO).

According to calculations by some experts, this puts the livestock sector on par with transport. The UN’s Intergovernmental Panel on Climate Change says transport is responsible for 14 percent of emissions.

Ruminants such as cattle, buffalo, sheep, and goats produce nitrous oxide, carbon dioxide, and methane, which is the most emitted gas and is released through belching.
