field producer jim wickens to the aceh region of north sumatra. here the leuser ecosystem is one of the last remaining strongholds for indonesian wildlife. it's a 6-million-acre protected park, but it's being illegally cut down to make room for palm oil. >> we've driven into the leuser ecosystem. this is a place of tigers, elephants, rhinos, and orangutans. it's supposed to be protected. but we've been tipped off by rangers here that there is illegal deforestation going on as we speak. we're going to go and try to film them and get right up close to the destruion. keep going. we've been hiking for hours to get here, right on the edge of where the trees are being cut down. i'm standing just meters from where the chainsaws are operating. i'm whispering because we've been told by our guides that these people are highly dangerous. [chainsaws in background] and it's likely to get violent if we move any closer. [m shoutsin distance] you can hear the trees falling through the canopy. it's one of the most biodiverse places on the planet. [choppng] and it'

traveling through the jungles of sumatra and actually following the track of the trailblazing geologists who for the very first time, managed to take the ideas of science and make them practical for oilmen who were actually, they did not care about science. they just wanted to know okay wise guys, how do i use your science to find the next big usher or flowing well? turns on the - up until the jungles of sumatra, no one had been able to use science to say, this is where you will find the next major oil discovery. this is where the next major gusher will be. not until the spectacle of italian - and his german colleague. actually undertook to do just that. they actually achieve something great. to this day, the language of geology and science permeates the oil industry. it is thanks to the trail blazers and these unknown figures that we actually enjoy the benefits of hydrocarbons today. finally there was the far east. now, the oil will come on china's insatiable desire for energy. and in answering that, in quenching that desire today just as back in marcus samuel's time, great fortunes can

but up until the jungles of sumatra, no one had been able to to use science to to say this is where you will find the next major oil discovery. this is where the next major gusher will be. not until the bespectacled italian and his german colleague named dr. c. schmidt actually undertook it to do just that. financial necessity drove them to that. they actually achieved something great. to this day, the language of geology and science permeates the oil industry, and it is thanks to the trail blazers and these unknown figures that we actually enjoy the benefits of hydrocarbons today. and finally, there was the ports of the far east. then, as now, the oil world and the energy world hung on china's insatiable desire for energy. in answering that, in quenching that desire -- today just as back in marcus samuel's time -- great fortunes can be made or lost. and so as i'm telling this story, i'm starting to uncover a lot of these connections. and for me, that's the most important part about "breaking rockefeller." because i love history, i love a great story, i love a great narrative-driven sto

so, i had a friend that had a connection in sumatra for green coffee.to sumatra, bought my first container. didn't know if i was overpaying for it. didn't know if it was good. and i came here and started cold-calling roasters in the area, and i got lucky. it was a great container. people were saying, "this is the best sumatran coffee i've tasted." it was $63,000 for that container. that same container, today, costs about $120,000. lemonis: i wish you'd have bought more. steve: i wish so, too. so, this is the warehouse. ♪ lemonis: holy [bleep] there's a lot of cash in here. steve: yes, there is. lemonis: there's a lot of green in here. steve: we import it for guys that want specialty coffee. say you own four restaurants and you want good coffee in your restaurants. you come to a guy like me. or i'll do private label. we do that for a lot of guys right now. lemonis: it's becoming even more clear to me that you're running two distinct businesses here. wholesale -- selling green roasted bags -- then the other business is opening up these cafes. steve: yep.
