Emma Thompson suggests climate change may drive people to eat their pets for protein

Emma Thompson issued a stark warning about the climate crisis, suggesting that conditions may become so dire that people will eat their pets for protein.

The actor delivered a mock weather forecast outside BBC Broadcasting House at an Extinction Rebellion protest in London, where she outlined the "gloomy projections," a Daily Mail video shows.

"Climate crisis trends show an increased chance of warmer, wetter winters and hotter, dryer summers, along with an increase of frequency and intensity of extremes," she said. "Better wrap up warm, stockpile food and remember there is a surprising amount of protein in the average household pet."

Standing in front of two maps that showed areas of the U.K. that are at risk of flooding by 2030, the climate activist warned if temperatures continued to rise in the country there could be a catastrophe.

"Looking ahead, we are on course to sail past our 1.5 degree centigrade target, putting us on track for long-lasting and irreversible change," the 60-year-old continued.

Thompson isn't the only actor vocally fighting against climate change. Jane Fonda has been arrested several times over her now-famous weekly climate change protests she's calling "Fire Drill Fridays." Other celebrities, like Ted Danson, Oscar nominee Diane Lane, "Coyote Ugly" star Piper Perabo, and "The Good Place" actor Manny Jacinto, have also joined the protests.
