Former California governor and actor Arnold Schwarzenegger said “stop whining” to environmentalists who despair at the approach of President Donald Trump's administration.

He said on Tuesday that he keeps hearing from environmentalists and policy experts lately: “What is the point of fighting for a clean environment when the government of the United States says climate change is a hoax and coal and oil is the future?”

Schwarzenegger told the Austrian World Summit, an event he helps organize, that his response is: “Stop whining and get to work.”

He pointed to examples of local and regional governments and companies taking their own action, including his own administration in California, and argued that 70% of pollution is reduced at local or state level.

“You can't just sit around and make excuses because one guy in a very nice White House on Pennsylvania Avenue doesn't agree with you,” he said.

Schwarzenegger added that attacking the president is “not my style” and he doesn't criticize any president when outside the U.S.

“I know that the people are sick and tired of the whining and the complaining and the doom and gloom,” he said. “The only way we win the people's hearts and minds is by showing them action that makes their lives better.”

The new U.S. administration has taken an axe to Biden-era environmental ambitions, rolled back landmark regulations, withdrawn climate project funding, and instead bolstered support for oil and gas production in the name of an “American energy dominance” agenda.

Schwarzenegger, a Republican, has devoted time to environmental causes since leaving political office in 2011.
