In an interview that was recorded earlier this year, Styles revealed that he no longer eats meat. Styles sat down with NPR Music's Stephen Thompson for a post-show interview where they talked about their admiration of Wisconsin football team the Green Bay Packers. A conversation that just started with two guys talking about football ended up with Styles revealing his new dietary preference.

Styles described a trip he once took to the Green Bay Packers' home stadium, Lambeau Field. Styles said the stadium served large, curved sausages called "horse collars." Thompson asked Styles if he had tried one of the horse collars. "Did you have a horse collar?" Thompson asked. "I did not. I don't eat meat," Styles quickly responded. "Yeah. No horse collar for me." Thompson mentioned that the stadium probably does not offer a veggie horse collar, to which Styles responded, "Not in Wisconsin. There's no veggie horse collar, which is a shame. But it's probably coming."

Flashback to July 2015, during one of his concerts with One Direction in San Diego. In between songs, Styles shouted to fans, "Does anybody like dolphins?" The crowd roared, "Yes." "Don't go to SeaWorld," the star responded.

Following Styles' comment, the number of social media mentions of SeaWorld grew from approximately 500,000 to around 2,500,000. The percentage of negative comments increased from roughly 25% to 85%. Meanwhile, SeaWorld reported an 84% drop in earnings during the second quarter of 2015, compared to the same period in 2014. There was also a 2% drop in visitor numbers. Styles became passionate about dolphins after watching 'The Cove' & 'Blackfish' documentaries.  Styles tweeted back in 2012. "Just watched 'The Cove' and it's one of the best and worst films I've ever seen. Unbelievable. Watch it and see what you think."
