Larissa de Macedo Machado - known better as Anitta - is a singer, dancer, and businesswoman with a huge following.
Taking to social media, she told her fans about how the film had inspired her to make some changes in her life this year.
Cowspiracy, created by Kip Andersen and Keegan Kuhn, looks at how animal agriculture is destroying the planet.
"[It] is a groundbreaking feature-length environmental documentary following intrepid filmmaker Kip Andersen as he uncovers the most destructive industry facing the planet today - and investigates why the world's leading environmental organizations are too afraid to talk about it," says the film's website.
"Animal agriculture is the leading cause of deforestation, water consumption and pollution, is responsible for more greenhouse gases than the transportation industry, and is a primary driver of rainforest destruction, species extinction, habitat loss, topsoil erosion, ocean 'dead zones', and virtually every other environmental ill. Yet it goes on, almost entirely unchallenged."
Inspired by Cowspiracy
Writing about the film on Instagram, Anitta wrote: "[My friend] Luiza has never been the kind of friend that tries to convert everyone to her way of thinking.
"But from so much admiring her work and worrying about our planet I asked for some advice from her. She advised me to watch this Netflix documentary Cowspiracy, that opened my eyes to several things.
"To challenge myself in 2019, I will be trying to change some of the environmentally-harmful habits I have. I suggest you also watch it - while not everyone has to agree with me, it's always good to receive all kinds of information and seek your own truth."
