0:00:06.920,0:00:08.520 [Why don't we eat bugs?] 0:00:09.416,0:00:12.124 For centuries, people have consumed bugs, 0:00:12.148,0:00:13.473 everything from beetles 0:00:13.497,0:00:15.351 to caterpillars, locusts, 0:00:15.375,0:00:18.304 grasshoppers, termites, and dragonflies. 0:00:18.328,0:00:20.449 The practice even has a name: 0:00:20.473,0:00:21.488 entomophagy. 0:00:21.512,0:00:24.257 Early hunter-gatherers[br]probably learned from animals 0:00:24.281,0:00:27.370 that foraged for protein-rich insects[br]and followed suit. 0:00:28.147,0:00:31.507 As we evolved and bugs[br]became part of our dietary tradition, 0:00:31.531,0:00:35.368 they fulfilled the role[br]of both staple food and delicacy. 0:00:35.392,0:00:39.250 In ancient Greece, cicadas[br]were considered luxury snacks. 0:00:39.274,0:00:43.016 And even the Romans found[br]beetle larvae to be scrumptious. 0:00:43.040,0:00:45.125 Why have we lost our taste for bugs? 0:00:45.149,0:00:47.971 The reason for our rejection[br]is historical, 0:00:47.995,0:00:49.541 and the story probably begins 0:00:49.565,0:00:52.773 around 10,000 BC in the Fertile Crescent, 0:00:52.797,0:00:54.248 a place in the Middle East 0:00:54.272,0:00:56.757 that was a major birthplace[br]of agriculture. 0:00:56.781,0:01:01.333 Back then, our once-nomadic ancestors[br]began to settle in the Crescent. 0:01:01.357,0:01:04.646 And as they learned to farm crops[br]and domesticate animals there, 0:01:04.670,0:01:06.084 attitudes changed, 0:01:06.108,0:01:09.530 rippling outwards towards Europe[br]and the rest of the Western world. 0:01:09.554,0:01:10.839 As farming took off, 0:01:10.863,0:01:13.940 people might have spurned[br]bugs as mere pests 0:01:13.964,0:01:15.508 that destroyed their crops. 0:01:15.532,0:01:18.367 Populations grew,[br]and the West became urbanized, 0:01:18.391,0:01:21.168 weakening connections[br]with our foraging past. 0:01:21.192,0:01:23.627 People simply forgot[br]their bug-rich history. 0:01:24.015,0:01:26.663 Today, for people not[br]accustomed to entomophagy, 0:01:26.687,0:01:28.256 bugs are just an irritant. 0:01:28.280,0:01:31.216 They sting and bite and infest our food. 0:01:31.240,0:01:33.692 We feel an "ick factor"[br]associated with them 0:01:33.716,0:01:37.118 and are disgusted[br]by the prospect of cooking insects. 0:01:37.142,0:01:40.441 Almost 2,000 insect species[br]are turned into food, 0:01:40.465,0:01:42.542 forming a big part of everyday diets 0:01:42.566,0:01:45.334 for two billion people around the world. 0:01:45.358,0:01:48.386 Countries in the tropics[br]are the keenest consumers, 0:01:48.410,0:01:50.387 because culturally, it's acceptable. 0:01:50.411,0:01:53.318 Species in those regions[br]are also large, diverse, 0:01:53.342,0:01:55.904 and tend to congregate in groups or swarms 0:01:55.928,0:01:57.870 that make them easy to harvest. 0:01:58.124,0:01:59.855 Take Cambodia in Southeast Asia 0:01:59.879,0:02:02.320 where huge tarantulas are gathered, 0:02:02.344,0:02:04.438 fried, and sold in the marketplace. 0:02:04.462,0:02:05.477 In southern Africa, 0:02:05.501,0:02:08.642 the juicy mopane worm is a dietary staple, 0:02:08.666,0:02:10.056 simmered in a spicy sauce 0:02:10.080,0:02:12.554 or eaten dried and salted. 0:02:12.578,0:02:17.229 And in Mexico, chopped jumiles[br]are toasted with garlic, lemon, and salt. 0:02:17.253,0:02:19.630 Bugs can be eaten whole to make up a meal 0:02:19.654,0:02:23.288 or ground into flour, powder,[br]and paste to add to food. 0:02:23.312,0:02:25.153 But it's not all about taste. 0:02:25.177,0:02:26.419 They're also healthy. 0:02:26.443,0:02:30.657 In fact, scientists say entomophagy[br]could be a cost-effective solution 0:02:30.681,0:02:33.503 for developing countries[br]that are food insecure. 0:02:33.527,0:02:36.466 Insects can contain up to 80% protein, 0:02:36.490,0:02:38.313 the body's vital building blocks, 0:02:38.337,0:02:40.856 and are also high in energy-rich fat, 0:02:40.880,0:02:44.264 fiber, and micronutrients[br]like vitamins and minerals. 0:02:44.288,0:02:47.228 Did you know that most edible insects[br]contain the same amount 0:02:47.252,0:02:50.223 or even more mineral iron than beef, 0:02:50.247,0:02:54.670 making them a huge, untapped resource[br]when you consider that iron deficiency 0:02:54.694,0:02:58.398 is currently the most common[br]nutritional problem in the world? 0:02:58.422,0:03:00.555 The mealworm[br]is another nutritious example. 0:03:01.492,0:03:05.390 The yellow beetle larvae are native[br]to America and easy to farm. 0:03:06.362,0:03:07.983 They have a high vitamin content, 0:03:08.007,0:03:09.246 loads of healthy minerals, 0:03:09.270,0:03:11.977 and can contain up to 50% protein, 0:03:12.001,0:03:15.230 almost as much as in an equivalent[br]amount of beef. 0:03:15.254,0:03:17.822 To cook, simply sauté in butter and salt 0:03:17.846,0:03:21.066 or roast and drizzle with chocolate[br]for a crunchy snack. 0:03:21.090,0:03:23.090 What you have to overcome in "ick factor," 0:03:23.114,0:03:25.485 you gain in nutrition and taste. 0:03:25.509,0:03:27.249 Indeed, bugs can be delicious. 0:03:27.273,0:03:29.276 Mealworms taste like roasted nuts. 0:03:29.300,0:03:31.195 Locusts are similar to shrimp. 0:03:31.219,0:03:34.864 Crickets, some people say,[br]have an aroma of popcorn. 0:03:34.888,0:03:38.587 Farming insects for food[br]also has less environmental impact 0:03:38.611,0:03:40.365 than livestock farms do 0:03:40.389,0:03:43.361 because insects emit[br]far less greenhouse gas 0:03:43.385,0:03:46.288 and use up less space, water, and food. 0:03:46.312,0:03:48.511 Socioeconomically, bug production 0:03:48.535,0:03:50.641 could uplift people[br]in developing countries 0:03:50.665,0:03:53.099 since insect farms can be small scale, 0:03:53.123,0:03:57.049 highly productive, and yet[br]relatively inexpensive to keep. 0:03:57.073,0:04:00.529 Insects can also be turned[br]into more sustainable food for livestock 0:04:00.553,0:04:02.735 and can be reared on organic waste, 0:04:02.759,0:04:04.108 like vegetable peelings, 0:04:04.132,0:04:06.998 that might otherwise[br]just end up rotting in landfills. 0:04:07.022,0:04:08.640 Feeling hungry yet?
