While nonprofit environmental groups and Indian tribes this week sued President Donald Trump's administration over his decision to drastically cut back two national monument sites in Utah, one for-profit company has also decided to step into the legal fray.

Patagonia, a Ventura, California-based company that sells outdoor apparel and gear and that has roughly $800 million in annual revenue, explained Wednesday why it was joining the fight. In a statement, CEO Rose Marcario said, “We aren't going to just stand by. Protecting public lands is a core tenet of our mission and vitally important to our industry, and we feel we need to do everything in our power to protect this special place.”

In a proclamation Dec. 4, Trump said the government would eliminate large parts of Bears Ears National Monument, as well as Grand Staircase Escalante National Monument.
