A group that promotes Welsh meat has been accused of "peddling climate change misinformation".
Hybu Cig Cymru (HCC) – Meat Promotion Wales posted on Facebook that it's a "myth" that "methane emissions from cows are responsible for global warming", attracting some criticism.
HCC chief executive Jose Peralta has since defended the post, adding that human activity was "responsible for global warning" and "within that human activity, cattle production is one of them".
But Rory Francis, director of charity Cymdeithas Eryri / Snowdonia Society, called the post "hugely disappointing".
"They should have a mission to explain that we should be talking to each other rather than peddling misinformation," he said.
Methane is the second most common greenhouse gas after CO2 and is released by livestock, such as cows and sheep, when they burp.
