Joaquin Phoenix and Rooney Mara are promoting a vegan lifestyle, with Phoenix having used various public appearances to highlight the benefits of veganism and criticize animal agriculture. The couple has also encouraged others to adopt vegan practices, such as adopting rather than eating turkeys on Thanksgiving. It appears that Phoenix and Mara are using their platform to raise awareness about the environmental and ethical implications of food choices, although the extent of their efforts and the impact of their message are not entirely clear.
