I REFER to “Scientists: Greenland losing ice faster than expected” (The Star, Dec 12). I wish to highlight a crucial and often overlooked contributor to greenhouse gas emissions and other environmental problems – animal husbandry.

The rearing of cattle for meat and dairy consumption has been proven to be one of the biggest contributors to climate change. Cows produce 150 billion gallons of methane every day as a by-product of their digestive processes. This is 84 times more potent than carbon dioxide in trapping heat.
