Ryan Gosling writes letter to Costco's CEO Craig Jelinek

Ryan Gosling has sent an open letter to US warehouse store Costco on Tuesday, which seeks to stop selling eggs from caged chicken by the retail company.

Gosling wrote the letter after watching the Humane Society of the United States' undercover video, which showed animal mistreatment by one of the store's major suppliers.

The Crazy, Stupid, Love actor has written to Costco chief executive Craig Jelinek in a letter published by the Humane Society.

Gosling wrote, "It is appalling that Costco has been selling these eggs with deceptive labelling on cartons featuring graphics of birds living out in a green pasture". "Video footage revealed abhorrent cruelty including rows and rows of birds confined in filth-laden cages with the mummified corpses of their cage mates ".

Gosling has a history of supporting animal welfare initiatives. In 2011, he was among Hollywood stars to support a petition against the treatment of egg-laying hens by fast food giant McDonald's.

He also wrote an op-ed published in the Globe and Mail in 2013 about the treatment of farmed pigs in Canada.

The actor called out Costco for its deceptive labeling on cartons, which feature graphics of birds living out in a green pasture. At the end, Ryan urged Costco to go cage-free.

In the end he concluded that he hopes that Costco will set plans now to go completely cage-free for its eggs.
