Transcript for Preview of ABC News documentary ‘Guardians of the Amazon’
There's a new report warning that the Amazon rain forest may be nearing a dangerous tipping point where instead of helping mitigate climate change it will make it worse becoming a net emitter of CO2 with even pope Francis sounding the alarm, I recently embedded with an indigenous tribe taking up arms to track down illegal loggers who are destroying their land. Here's a preview of our ABC news documentary called "Guardians of the Amazon." Okay, so they're telling us they have a prisoner. He's got his hand on his pistol, another hand on a machete. We have no idea what we're getting into. I've been all over the world covering all sorts of wild stories in war Zones. This is like a secret war happening in the depths of the jungle. These indigenous folks say they're protecting their own land, and they're protecting the planet for the rest of us. Incredible story. I'm sure your wife loves to see that video, by the way. Do you tell her after you get back just how dangerous it was? I usually say I'm going to -- somewhere interesting. I'll tell you about it when I get back. I do want to point out you can watch this new documentary which is called "Guardians of the Amazon" throughout the weekend on our new streaming channel which is called ABC newslive and will hit hulu on Wednesday. I remember you took -- you disappeared for a few weeks to do that. I didn't think you were coming back. Yeah, it was really interesting and for somebody interested in climate and weather, it is up your alley. Very important story and can't wait to watch that documentary. Thank you. Appreciate it. Glad you're back safe.
