This Argentinian bull has a device attached to its back to prevent methane escaping when it belches.

The gas is collected from the bull's stomach through a small pipe and compressed in a canister. Every day one animal produces enough fuel to drive a car one kilometre.

According to the UN, 18% of greenhouse gas emissions are produced by livestock.
