1 00:00:03,169 --> 00:00:08,608 It is estimated there will be two billion more people on the planet by mid-century. 2 00:00:08,708 --> 00:00:14,180 Growing enough food for this booming world population without serious environmental impacts 3 00:00:14,280 --> 00:00:18,618 is one of the greatest challenges to face humanity. 4 00:00:18,718 --> 00:00:22,022 The same way that we have been through the Green Revolution, with aquaculture right now 5 00:00:22,122 --> 00:00:25,392 we re going through the Blue Revolution. 6 00:00:25,492 --> 00:00:31,598 Consumer demand for seafood is on the rise, as doctors tout its health benefits and developing 7 00:00:31,698 --> 00:00:36,469 nations can afford more costly sources of protein. 8 00:00:36,569 --> 00:00:42,275 By the year 2030, we re going to have to produce an additional 30 million metric tons 9 00:00:42,375 --> 00:00:46,679 of seafood to feed the human population. 10 00:00:46,780 --> 00:00:53,420 At the same time, wild fish stocks are either depleted, overfished, or stagnant at best. 11 00:00:53,520 --> 00:00:59,959 If we re going to actually protect our oceans, we have to make that transition from hunting-gathering 12 00:01:00,060 --> 00:01:01,294 to farming. 13 00:01:01,394 --> 00:01:04,464 It s what we ve done with all of our other food production. 14 00:01:04,564 --> 00:01:10,937 To walk into a restaurant and order a steak of a wild cow, that doesn t exist anymore. 15 00:01:11,037 --> 00:01:17,577 The reality is we are farming just about everything else that we re consuming, so why not fish? 16 00:01:17,677 --> 00:01:23,850 We re already farming more than half the global seafood production. 17 00:01:23,950 --> 00:01:30,423 We re farming more seafood than we are beef globally, and it s only going to continue. 18 00:01:30,523 --> 00:01:35,095 Because of their cold-blooded nature and the fact that they don t need to expend as much 19 00:01:35,195 --> 00:01:41,267 energy living in a buoyant environment, fish require a lot less feed than land animals, 20 00:01:41,367 --> 00:01:45,472 decreasing the demand on Earth s resources. 21 00:01:45,572 --> 00:01:48,508 Aquaculture is the most efficient form of animal protein production. 22 00:01:48,608 --> 00:01:51,611 Whether we like it or not, aquaculture has become mainstream. 23 00:01:51,711 --> 00:01:56,749 There s people who are still thinking negatively about aquaculture, but those are the dark 24 00:01:56,850 --> 00:02:00,453 ages. 25 00:02:00,553 --> 00:02:09,229 Habitat destruction, water pollution, disease, and food safety scares, caused mainly by crammed 26 00:02:09,329 --> 00:02:17,537 nearshore aquaculture operations in Asia, have given the industry a bad name. 27 00:02:17,637 --> 00:02:25,011 But experts say newer, more innovative ways of farming the sea are the way of the future. 28 00:02:25,111 --> 00:02:31,451 One way to increase fish production in a sustainable way is to move aquaculture operations offshore 29 00:02:31,551 --> 00:02:37,891 where there is plenty of available space and strong currents flush out the pens to 30 00:02:37,991 --> 00:02:40,627 avoid polluting sensitive ecosystems. 31 00:02:40,727 --> 00:02:45,765 We re going to need to double the global seafood supply in order to meet projected 32 00:02:45,865 --> 00:02:47,600 demand. 33 00:02:47,700 --> 00:02:50,870 And we think the only way to really do that is to move farms into the open ocean where 34 00:02:50,970 --> 00:02:56,309 we have this vast environment that can support that kind of growth. 35 00:02:56,409 --> 00:03:01,915 In terms of a sustainable place to raise fish, the open ocean is fantastic. 36 00:03:02,015 --> 00:03:07,153 These offshore submersible cages are marvelous pieces of underwater engineering. 37 00:03:07,253 --> 00:03:12,292 There is no doubt that those are the most advanced aquaculture systems in the world. 38 00:03:12,392 --> 00:03:15,895 It is the future of seafood production. 39 00:03:15,995 --> 00:03:21,935 Without aquaculture, we re not going to have enough seafood to supply the world. 40 00:03:22,035 --> 00:03:25,405 What does the seafood of the future look like? 41 00:03:25,505 --> 00:03:29,505 How do we sustainably grow fish from farm to fork?
