During a Wednesday campaign speech, real-estate mogul Donald Trump launched into a one-minute complaint about environmentalists and hairspray. Trump first mocked US President Barack Obama for prioritizing climate-change policies despite flying around the planet in “an old Boeing 747, with the old engines and spewing stuff.”
“So he’s got a problem with the carbon footprint!” Trump exclaimed. The Republican presidential front-runner quickly pivoted to the topic of hairspray. This was an apparent reference to the chlorofluorocarbons, or CFCs, that were once found in aerosol cans but were phased out after scientists found that they diminished Earth’s ozone layer.
“You can’t use hair spray because hair spray is going to affect the ozone,” Trump said, speaking at a rally in Hilton Head Island, South Carolina. Trump then returned to mocking Obama for thinking that global warming is a more pressing issue than terrorism.
