Colin Firth, who won an Oscar in 2011 for his regal role as a stuttering monarch in "The King's Speech," is now using his voice to help what has been dubbed "Earth's most threatened tribe."

The 51-year-old English actor stars in a PSA that urges people to help save the Awá from illegal loggers in the Brazilian Amazon.

The video, posted on the website of leading advocate Survival International, deals with the illegal deforestation in northeast Brazil. The group says one a few hundred Awá people remain in the Amazon and many are losing their homes and lives to illegal loggers. The campaign's goal is to persuade Brazil's Justice Minister to send in federal police to clear out the invaders.

"The Awá's forest is being illegally cut for timber," Firth says in the PSA. "When the loggers see them, they kill them. Their bows and arrows are no match for guns. And at any other time in history, that's where it would end. Another people wiped off the face of the Earth, forever. But we're going to make sure the world doesn't let that happen."

"One man has the power to stop the loggers: Brazil's Minister of Justice," Firth continued. "But right now it's just not his priority. Let's push it up his list."

On Survival International's website, visitors can donate money, send a pre-coordinated message to the Minister of Justice in Brazil or share the information on their social media pages.

According to National Geographic, the Awá are one of only two nomadic hunter-gatherer tribes left in Brazil. The unique tribe has a profoundly warm relationship with their forest, which provides them with food, shelter and spiritual solace.
