I think going on a boat trip through the Amazon, not a hiking one— —where we’re going through some really… there’s areas where you can get permits to go through areas where no one’s allowed to go.

Because we should say, kind of the obvious thing is, as far as anyone remembers any encounters, any minimal, small encounters with these tribes— …have been violent.

Let me look this up on Perplexity: what are the technologies we modern humans have that the Mashco Piro do not? It’s just interesting to think about the kind of technologies we take for granted.

That there’s going to be pain, there’s going to be suffering along the way. You have a really nice post… …That I recommend people watch about just this.

There’s that quote that someone less qualified than you is living your dream life and has your dream job right now, and I am the poster child for that because I failed out of high school and started taking unmatriculated college classes and going to the jungle with my friend JJ and just doing it for the sheer love of it for years, almost a decade, before anything surfaced.

Because our first conversation led to the first surge where people realized what Jungle Keepers was— —and then because we got this surge of support, we were able to expand our work, protect more acres.

It’s one of the last places that’s untouched. This changed everything because we realized that along with the butterflies and the monkeys and the jaguars and the trees and the ecosystem, there’s also a human culture that will, in the next few years, cease to exist, that will be exterminated if we don’t protect them.

These landowners are going to sell their forest to the logging companies because owning 10,000 acres of the Amazon doesn’t help you if you’re a third generation jungle man.

There’s a deep optimism to that. And you actually write in the book, which I really like, I think somewhere in the beginning, quote: “Given all the death and destruction I’ve witnessed, it would be easy to slip into the popular anti-human narrative that we are a plague on the planet and there’s nothing that can be done, but my career in conservation has given me a glimpse into an alternate narrative.
