He also discussed battling oil companies "for knowingly killing people all over the world". The former governor of California shared that he is now in talks with several private law firms and a public push around the effort is in the works.
During an interview with Politico's "Off Message" podcast, he related oil companies to tobacco companies and called it "absolutely irresponsible" to not have a warning label on a product a company knows kills people.
"This is no different from the smoking issue".
On the podcast, Schwarzenegger made a comparison between oil and tobacco, a product that kills 480,000 people per year in the USA, according to the CDC.
Schwarzenegger added that "if you walk into a room and you know you're going to kill someone, it's first degree murder". "I never know really why the Russians make him say certain things", Schwarzenegger riffed.More news: Dragon Ball FighterZ Releases Broly Trailer
Like many other environmental advocates, Schwarzenegger sees a direct parallel between what happened with the tobacco industry and what is now happening with the oil industry.
The actor compared big oil's alleged cover up to the tobacco industry's efforts to hide the dangers of smoking and said, like cigarettes, every product that uses fossil fuels should have a warning label.
In a 2015 Facebook post, Schwarzenegger said 7 million people die annually from pollution, while 19,000 die daily from fossil fuel pollution.
"We need to go an alternative route", he said.
In addition to the Big Oil legal action announcement, Schwarzenegger took a moment to joke about President Donald Trump during the podcast.More news: Slovak prime minister offers to resign to 'solve the political crisis'
And because people should be made aware of how much their lifestyle contributes to harming the environment, he believes any product that was produced, or processed, using fossil fuels (hint: that's almost everything we buy) should have a label on it.
Then this January, New York City's mayor Bill de Blasio threatened Big Oil with more lawsuits, comparing the industry to the tobacco giants, saying they "systematically poisoned the Earth, knew about it, covered it up, explained it away, tried to hook people more and more on their product".
The fact that oil companies knew about the dangers of climate change and denied the evidence has become known globally as the #Exxonknew scandal.
"Every gas station, every auto should have a warning label on it; every product that has fossil fuels should have a warning label on it".More news: WhatsApp Won't Share UK User Data With Facebook (for Now)
