The star, who is well known for her appearance in Thor and 2 Broke Girls, made the announcement to her 3.5 million Instagram followers.
‘Definitely going plant-based’
“I will never be the same. David Attenborough, this film is a handbook for how the human race can come together to stop destroying our round blue home,” Dennings wrote.
“I’m definitely going plant-based starting tomorrow. Except for butter. But other than that.”
The post, which received more than 8,500 likes, was flooded with vegans suggesting vegan alternatives to butter such as EarthBalance and Miyoko’s.
On Instagram Stories, Dennings described the film as ‘incredible’ and ‘life changing’ adding that humans ‘are the worst’.
A Life On Our Planet
A Life On Our Planet has also inspired a national newspaper journalist to go vegan.
Claudia Tanner, a writer for i, and vegetarian from the age of eight, ditched her ‘cheese addiction’ after hearing Attenborough urgent message that the planet can’t support billions of meat-eaters.
“And so for the last fortnight, at age 40, I’ve given up Gouda and got inspiration from the tonnes of online recipes out there. I’ve gone from scratching my head about what to eat to not being able to work though my recipe wish list fast enough,” Tanner said.
“I eat a wider range of food now as I experiment with new ingredients. And I consume more protein-rich foods than before, for instance edamame tagliatelle and pure soy mince… And as for feeling denied, I genuinely don’t. I’m discovering new flavors and using lots of spices.”
