Former Entourage actor Adrian Grenier, who previously referred to capitalism as oppressive, is attacking Republican presidential frontrunner Donald Trump for his tweets on global warming.

“It’s extremely destructive,” Grenier told The New York Daily News of past statements made on Twitter by Trump, who has described climate change as “bulls—t,” among other things.

Trump has previously tweeted:



Grenier described Trump as “extremely short-sighted,” and stated, “Climate change is real.”

“We shouldn’t be arguing about whether or not it’s real,” he said. We should be arguing about how we’re going to make the world less polluted.”

The actor and environmental activist also told the Daily News, “I don’t even know why we’re paying attention. I mean, look, the naysayers out there are so far and few between.”

Grenier concluded: “The question is, how are we going to improve our lives – our quality of life – for people around the world?”
