This is the Taushiro language. In modern times, only a handful of people have ever heard it spoken. That’s because this man, Amadeo García García, is the last person on Earth who speaks it. Our journey starts here, on the edge of the Amazon River, in the heart of Peru. We wanted to meet Amadeo to understand how a language can disappear. Maybe only a few thousand people spoke Taushiro at its peak. But it’s a language that’s been around for centuries. We’re headed deep into the Amazon jungle so remote that the only way there is a 10-hour boat ride. It’s difficult to quantify the importance of language. Our speech defines who we are and who we aren’t. It’s what binds us, what divides us. It gives us history, and grants the ability to look back and evolve our culture and our understanding over the decades. For the Taushiro, that all ends here, with this man. This is how we came to find Amadeo García García. He resides here, in the remote village of Intuto. Amadeo grew up even deeper inside the Amazon. Until he was a teenager, his family was part of an uncontacted tribe. They lived off the land, away from modern medicine and technology. Slowly, they started to die off. Amadeo hasn’t had a real conversation in Taushiro since his brother died. But he says he still dreams in Taushiro. Amadeo hadn’t spoken to his son in months. While we were visiting, he borrowed our phone to catch up. They communicate in Spanish. Amadeo’s wife left him with five children he couldn’t care for. They were adopted by a Christian missionary and raised in Puerto Rico, over 1,000 miles away. So the opportunity to learn Taushiro and inherit the culture was lost. There are efforts to preserve the Taushiro language, but it will likely go when Amadeo goes. For Amadeo, the language died a long time ago. There’s no need for language when you’re alone.
