WEBVTT 00:00:08.433 --> 00:00:15.351 I grew up on a beach in an island called Tasmania, a beautiful place. 00:00:16.440 --> 00:00:21.190 It gave me the opportunity to meet and interact with incredible creatures, 00:00:21.681 --> 00:00:26.633 and it was where I developed a deep connectivity with the ocean. 00:00:26.833 --> 00:00:30.610 Now, Tasmania is one of the most beautiful islands on the planet. 00:00:30.610 --> 00:00:35.470 But 30 years ago, the city I grew up in had a terrible problem. 00:00:35.470 --> 00:00:40.330 The ocean was polluted with the outfall from heavy industry. 00:00:40.330 --> 00:00:42.495 There was a pulp and paper mill, 00:00:42.505 --> 00:00:46.806 a paint pigment plant and a slaughterhouse among them. 00:00:47.216 --> 00:00:51.576 These were causing rashes on the bodies of swimmers and surfers, 00:00:51.576 --> 00:00:55.568 and when you got out of the water, you had sore red eyes. 00:00:55.888 --> 00:00:57.768 Burnie, at that time, 00:00:57.768 --> 00:01:01.728 had one of the highest incidence of cancer in Australia. 00:01:02.388 --> 00:01:07.348 Following the lead of three generations of journalists in my family, 00:01:07.578 --> 00:01:11.008 I made it my investigative mission to uncover 00:01:11.008 --> 00:01:13.899 whether these industries were, in fact, responsible 00:01:13.899 --> 00:01:16.119 for the illnesses we were seeing 00:01:16.119 --> 00:01:20.908 and also the poor state of the ecosystem along the coastline. 00:01:21.669 --> 00:01:25.507 So, I got a laboratory to test the waters around Burnie, 00:01:25.507 --> 00:01:29.459 and they found that the outfall from the pulp and paper mill 00:01:29.459 --> 00:01:32.009 contained organic chlorines. 00:01:32.009 --> 00:01:37.161 And these had dangerous cancer-causing dioxins. 00:01:37.831 --> 00:01:40.070 So, I put these findings to the state government 00:01:40.070 --> 00:01:41.960 and the minister for the environment, 00:01:41.960 --> 00:01:43.590 and he admitted for the first time 00:01:43.590 --> 00:01:48.290 that they knew about these organic chlorines and these dioxins 00:01:48.290 --> 00:01:51.801 and that they were dangerous, but they hadn't informed the public. 00:01:52.023 --> 00:01:57.175 So, I published my stories in the local newspaper, 00:01:57.901 --> 00:02:02.413 and it caused a storm of protest across Australia. 00:02:04.283 --> 00:02:08.768 National papers declared Burnie "Australia's dirtiest city." 00:02:08.768 --> 00:02:12.707 I wasn't very popular with our local tourism authority, I can tell you. 00:02:13.180 --> 00:02:15.939 I was 20 years of age at the time. 00:02:17.529 --> 00:02:19.647 Shortly after those stories were published, 00:02:19.647 --> 00:02:21.999 the industries started to close down, 00:02:22.589 --> 00:02:29.449 and today, Burnie has some of the bluest water along the coastline, 00:02:29.449 --> 00:02:33.366 and the fish have returned to the waters around the city. 00:02:34.248 --> 00:02:38.418 I learned then about the power of the media. 00:02:42.349 --> 00:02:46.299 Now, as I developed my skills in the media 00:02:46.779 --> 00:02:50.229 through newspapers, radio and television, 00:02:50.629 --> 00:02:53.038 I also developed a passion for film. 00:02:53.038 --> 00:02:58.748 Film gave me the ability to tell stories and to make documentaries 00:02:58.748 --> 00:03:03.698 that gave voice to silent creatures like the worms from my childhood. 00:03:05.477 --> 00:03:08.613 But I also had a deep love 00:03:08.613 --> 00:03:13.833 for a particular species that had consumed my time as a child, 00:03:13.833 --> 00:03:18.188 and that was the blue whale, an immense creature, 00:03:18.194 --> 00:03:20.896 also incredibly shy. 00:03:21.686 --> 00:03:27.455 An opportunity came to film a documentary off the south coast of Sri Lanka. 00:03:27.455 --> 00:03:30.144 It was the culmination, for me, of a life's dream. 00:03:30.144 --> 00:03:34.154 Now, blue whales are the biggest animals ever to have lived. 00:03:34.154 --> 00:03:36.014 They're bigger than any dinosaur. 00:03:36.014 --> 00:03:38.263 They grow up to about 37 meters long. 00:03:38.393 --> 00:03:40.943 They have a heart as big as a car. 00:03:40.943 --> 00:03:43.007 But they were hunted almost to extinction, 00:03:43.007 --> 00:03:46.357 and as a result, they're extremely elusive. 00:03:46.357 --> 00:03:51.377 Trying to find them is like trying to find a needle in a massive haystack. 00:03:52.083 --> 00:03:55.673 We went up and down the coastline of Sri Lanka for weeks on end, 00:03:55.679 --> 00:03:57.695 searching for these whales. 00:03:57.695 --> 00:04:01.845 We would see a spout in the distance, we'd head towards it. 00:04:02.055 --> 00:04:05.736 We would get our cameras into our underwater housings. 00:04:05.967 --> 00:04:09.696 We'd get our teams into the water, we'd move towards the whales, 00:04:10.038 --> 00:04:11.906 and then we would never see them again. 00:04:11.906 --> 00:04:16.080 And this happened day after day after day after day. 00:04:16.080 --> 00:04:19.611 And if you want to know what it's like to go crazy, 00:04:19.611 --> 00:04:22.580 look out into an open ocean, empty open ocean 00:04:22.580 --> 00:04:25.930 for day after day after day after day. 00:04:25.930 --> 00:04:28.740 That's where coffee became a big friend of mine. 00:04:29.769 --> 00:04:34.360 So, we searched near an underwater seamount, 00:04:34.360 --> 00:04:35.995 and this is where krill gather 00:04:35.995 --> 00:04:38.075 because they're brought in by the currents. 00:04:38.075 --> 00:04:41.445 And we knew the whales would head there because they eat krill. 00:04:41.445 --> 00:04:43.055 We didn't find whales. 00:04:43.055 --> 00:04:47.185 What we found was something very significant. 00:04:47.185 --> 00:04:50.424 It was a floating landfill of plastic. 00:04:50.851 --> 00:04:56.542 This was a massive slick of detritus as far as the eye could see. 00:04:57.183 --> 00:05:03.574 It contained old fishing nets, bait boxes, plastic bottles, used lighters, 00:05:03.574 --> 00:05:07.252 even unopened biscuits - the wastage of humanity. 00:05:07.252 --> 00:05:09.613 It was absolutely dreadful. 00:05:09.743 --> 00:05:14.123 It was the sign of a coming tragedy. 00:05:14.613 --> 00:05:16.741 We didn't know that at the time. 00:05:16.918 --> 00:05:20.302 We kept looking for the whales for three weeks, 00:05:20.302 --> 00:05:21.692 and our time finally ran out. 00:05:21.692 --> 00:05:25.652 We had to head back to port because our visas were about to expire. 00:05:25.942 --> 00:05:29.241 But I'm an incredibly stubborn individual, 00:05:29.241 --> 00:05:34.732 and I hadn't come this far and worked this hard to give up this easily, 00:05:34.732 --> 00:05:39.913 so I refused to allow the cameras to be packed away. 00:05:40.281 --> 00:05:45.334 I refused to allow the dive tanks to be put under the boat. 00:05:47.072 --> 00:05:50.763 I was going to exhaust every possible moment we had on the water. 00:05:51.632 --> 00:05:57.073 Now, when someone yells "Whale," your adrenaline really spikes. 00:05:57.712 --> 00:06:01.792 Someone yelled "Whale," and my adrenaline shot through the roof. 00:06:02.723 --> 00:06:09.103 There, 100 meters off our bow, was a spout - 00:06:09.573 --> 00:06:10.934 (Splashing sound) 00:06:10.934 --> 00:06:13.337 high and very visible. 00:06:14.898 --> 00:06:16.937 We cut the motors on the boat, 00:06:17.716 --> 00:06:19.564 we put the dive teams in the water, 00:06:19.564 --> 00:06:22.614 and the cameras, and I got in with the crews, 00:06:22.614 --> 00:06:27.896 and we slowly finned over towards what was a pot of whales. 00:06:27.896 --> 00:06:31.152 And as we got closer, we realized this was a family of eight, 00:06:31.152 --> 00:06:34.904 and in this family of eight whales was a juvenile. 00:06:34.904 --> 00:06:38.554 And when I say "juvenile," he was 15 meters long. 00:06:39.054 --> 00:06:42.021 And he was as curious of us as we were of him, 00:06:42.021 --> 00:06:46.603 and with the big flick of his tail, he dived incredibly deep and out of sight, 00:06:46.873 --> 00:06:51.264 and then, moments later, he came up right between our cameras, 00:06:52.134 --> 00:06:54.344 and we had, for the first time, 00:06:54.344 --> 00:06:57.494 footage, under water, on cinematic cameras, 00:06:57.494 --> 00:06:59.574 of a juvenile blue whale. 00:06:59.574 --> 00:07:02.583 It was a profound moment for us. 00:07:03.824 --> 00:07:07.155 As we were heading back to port and I was reflecting on the shoot, 00:07:07.155 --> 00:07:11.259 I realized that these whales were resting and probably feeding 00:07:11.259 --> 00:07:15.602 right near where we had filmed this floating landfill of plastic. 00:07:15.602 --> 00:07:19.591 Now, whales, when they feed - blue whales - they open their mouths, 00:07:19.591 --> 00:07:24.490 they suck in thousands of liters of water, and they expel that water, 00:07:24.490 --> 00:07:28.323 leaving behind the krill in their baleen, or their teeth. 00:07:28.332 --> 00:07:32.680 But whales can't tell the difference between krill and plastic. 00:07:34.222 --> 00:07:40.402 The Sri Lankan expedition was the start of an epic quest for us, 00:07:40.762 --> 00:07:43.443 but it posed more questions than it answered: 00:07:43.443 --> 00:07:45.833 If whales were consuming plastic 00:07:45.833 --> 00:07:49.223 in a pristine environment like the Indian Ocean, 00:07:49.223 --> 00:07:53.642 what was happening to marine life in oceans in other parts of the planet? 00:07:54.081 --> 00:08:00.824 And if as we'd found out that 350 million tons of plastic were being made that year, 00:08:00.824 --> 00:08:03.943 how much of that was ending up in the oceans? 00:08:03.943 --> 00:08:08.013 And if marine life in oceans around the world were consuming plastic, 00:08:08.014 --> 00:08:10.224 and we're at the top of the food chain, 00:08:10.224 --> 00:08:12.564 what did that mean for human health? 00:08:13.244 --> 00:08:18.464 Well, we gathered teams and crews and scientists, 00:08:18.464 --> 00:08:23.220 and we traveled for four years around the globe to 20 different locations 00:08:23.220 --> 00:08:27.624 to answer these questions for our film "A Plastic Ocean." 00:08:28.163 --> 00:08:30.454 Our investigation was relentless. 00:08:30.454 --> 00:08:35.304 For example, we found that 70% of plastic sinks. 00:08:36.044 --> 00:08:40.144 Now, what we'd seen then was just the tip of the iceberg, 00:08:40.144 --> 00:08:44.444 so we hired a research vessel and two submarines, 00:08:44.444 --> 00:08:46.124 and we went to the Mediterranean, 00:08:46.124 --> 00:08:48.583 and we traveled to the bottom of the Mediterranean, 00:08:48.583 --> 00:08:50.633 1,600 meters below the surface, 00:08:50.633 --> 00:08:55.033 to see what happened to plastic in the absence of light, 00:08:55.033 --> 00:08:56.644 in the absence of oxygen. 00:08:57.524 --> 00:08:59.633 We traveled thousands of kilometers 00:08:59.633 --> 00:09:04.063 to the Pacific, to islands where seabirds were ingesting plastic, 00:09:04.063 --> 00:09:05.703 mistaking it for food. 00:09:07.474 --> 00:09:13.723 One of the most powerful scenes in the film is of a heroic little seabird 00:09:13.723 --> 00:09:15.424 called a shearwater. 00:09:15.424 --> 00:09:19.624 These birds, chicks, were turning up dead in their hundreds 00:09:19.624 --> 00:09:22.164 on an island called Lord Howe Island. 00:09:23.194 --> 00:09:25.834 And when we opened the stomachs of these birds, 00:09:25.834 --> 00:09:29.873 we found them filled with plastic. 00:09:30.513 --> 00:09:33.732 In one particular little chick, 00:09:34.112 --> 00:09:39.122 we found 272 pieces of plastic. 00:09:39.532 --> 00:09:44.384 That's equal to about 12 pizzas if you were to eat them all at once 00:09:44.384 --> 00:09:46.394 and put them in your stomach. 00:09:46.394 --> 00:09:49.664 Can you imagine the pain this animal was going through? 00:09:49.664 --> 00:09:54.504 As we opened other chicks, we found a red bottle cap, 00:09:54.504 --> 00:09:55.884 and I realized at that moment 00:09:55.884 --> 00:10:01.573 that that bottle cap could have been a bottle cap I threw away years earlier 00:10:01.573 --> 00:10:05.645 without understanding the consequences of my actions. 00:10:06.244 --> 00:10:09.997 Now, if I'm a surfer, a diver and an ocean explorer, 00:10:09.997 --> 00:10:14.994 and I didn't realize the consequences of my actions to the natural world 00:10:14.994 --> 00:10:16.064 eight years ago, 00:10:16.064 --> 00:10:19.255 how could I expect anyone else to understand theirs? 00:10:20.404 --> 00:10:27.243 We needed awareness, and "A Plastic Ocean" would become the tool for that awareness. 00:10:30.401 --> 00:10:32.900 Now, scientists told us 00:10:32.900 --> 00:10:39.280 that we would dispose of between 8 and 12 million tons of plastic 00:10:39.280 --> 00:10:42.229 into the world's oceans every year. 00:10:42.838 --> 00:10:45.920 How on earth did we allow that to happen? 00:10:46.748 --> 00:10:52.190 Well, the answer's simple: We were told plastic would make our lives easier. 00:10:52.639 --> 00:10:55.060 We would no longer have to do the washing up. 00:10:55.060 --> 00:10:57.270 It would keep our food fresher. 00:10:57.270 --> 00:11:01.174 It would protect our consumer products like no other material before it. 00:11:01.174 --> 00:11:03.524 And in many ways, it did just that. 00:11:05.369 --> 00:11:10.189 But we were also told that plastic could be used just once and thrown away. 00:11:10.970 --> 00:11:12.331 Think about that. 00:11:13.301 --> 00:11:16.485 Plastic is the most durable product we have ever made. 00:11:16.485 --> 00:11:20.956 How can the most durable product we've ever made be considered disposable? 00:11:21.556 --> 00:11:24.966 The answer is, "It can't. It isn't." 00:11:24.966 --> 00:11:30.715 Every piece of plastic ever made is still on the Earth unless it's been burned. 00:11:33.253 --> 00:11:34.901 In the past decade, 00:11:35.241 --> 00:11:39.892 we have produced more plastic than the entire century before that. 00:11:40.352 --> 00:11:41.371 Fifteen years ago, 00:11:41.371 --> 00:11:44.261 the United States' Center for Decease Control 00:11:44.261 --> 00:11:50.082 released a study which showed that more than 92% of all Americans 00:11:50.413 --> 00:11:54.679 contain chemicals related to plastic in their blood and their urine. 00:11:54.930 --> 00:11:56.413 And more disturbing than that 00:11:56.413 --> 00:12:01.763 was that children between the ages of 6 and 11 have twice as much. 00:12:02.433 --> 00:12:08.222 Now, plastic chemical like phthalates and bisphenol As contain compounds 00:12:08.762 --> 00:12:13.822 which have estrogenic activity, which mimic and sometimes block 00:12:13.832 --> 00:12:16.802 the natural hormonal production of our bodies. 00:12:17.343 --> 00:12:22.702 Recent research shows that these can cause endocrine disruptive decease, 00:12:22.702 --> 00:12:27.954 cancer, diabetes, fertility and other reproductive issues. 00:12:29.102 --> 00:12:32.790 But plastic has become an integral part of our society. 00:12:32.790 --> 00:12:34.122 It's a very useful tool. 00:12:34.122 --> 00:12:39.812 My cameras, my car, my computers - all contain plastic components. 00:12:39.812 --> 00:12:44.170 But our habitual consumption of single-use plastic 00:12:44.170 --> 00:12:47.420 is destroying life-giving environments. 00:12:47.420 --> 00:12:51.242 It's killing other species, and it's polluting our food source. 00:12:51.672 --> 00:12:55.402 So, what will happen if we don't stop production of plastic? 00:12:55.402 --> 00:12:59.582 Well, as of 2015, we had produced, globally - 00:12:59.582 --> 00:13:03.222 since plastic production has begun in the '50s - 00:13:03.222 --> 00:13:06.472 8.3 billion tons of plastic. 00:13:06.742 --> 00:13:08.742 8.3 billion tons. 00:13:09.551 --> 00:13:13.530 6.3 billion tons of that has become waste, 00:13:13.973 --> 00:13:19.902 and of that 6.3 billion tons of waste, only 9% has been recycled. 00:13:21.111 --> 00:13:27.073 By 2050, our population will explode to more than 9.8 billion people, 00:13:27.422 --> 00:13:32.611 and by then, we will be sending 12 billion tons of plastic to landfill 00:13:32.611 --> 00:13:34.142 and to the environment. 00:13:34.412 --> 00:13:35.932 It's staggering. 00:13:36.172 --> 00:13:37.742 So, what's the solution? 00:13:38.832 --> 00:13:42.283 Well, we need to stop our addiction to single-use plastic. 00:13:42.283 --> 00:13:45.702 We need to move to a zero-waste society. 00:13:46.943 --> 00:13:52.061 We need to change the very social and financial paradigms 00:13:52.061 --> 00:13:56.146 that consider single-use plastic a useful resource. 00:13:56.615 --> 00:14:00.496 We need a multifaceted approach to this problem, 00:14:00.496 --> 00:14:04.594 with input from governments, retailers, manufacturers, consumers. 00:14:04.856 --> 00:14:07.866 And we need to integrate new ideas, 00:14:07.866 --> 00:14:12.086 like new legislation, circular economies 00:14:12.086 --> 00:14:16.665 and cradle-to-grave responsibility for manufacturers and retailers. 00:14:16.665 --> 00:14:17.887 And as consumers, 00:14:17.887 --> 00:14:22.097 each one of us needs to be smarter about the choices we make. 00:14:22.097 --> 00:14:24.938 We all need to rethink plastic. 00:14:25.207 --> 00:14:27.027 So, how do we do that? 00:14:28.017 --> 00:14:31.127 Well, we stop buying single-use plastics, to start with. 00:14:32.036 --> 00:14:35.537 When I'm at home, and I have a drink, I don't need to use a straw. 00:14:35.548 --> 00:14:38.248 So why do I need a straw when I go to a restaurant? 00:14:38.467 --> 00:14:39.696 I don't. 00:14:40.226 --> 00:14:46.788 Why would I spend up to 2,000% more buying water in a plastic bottle 00:14:46.788 --> 00:14:51.526 when it costs me so much less to refill a steel container from the tap, 00:14:51.526 --> 00:14:53.518 and it's quite often healthier? 00:14:53.518 --> 00:14:54.887 It makes no sense. 00:14:55.917 --> 00:15:00.498 Take a bag with you, a reusable bag, when you go shopping. 00:15:00.498 --> 00:15:06.178 And when you get to the supermarket or the market, call the manager over. 00:15:06.417 --> 00:15:10.980 At the checkout, unwrap all the plastic from all of those fruits and vegetables 00:15:10.980 --> 00:15:13.880 that have been individually wrapped with this plastic stuff, 00:15:13.880 --> 00:15:15.236 and give it to the manager, 00:15:15.236 --> 00:15:17.296 back to the supermarket, back to the market, 00:15:17.296 --> 00:15:19.157 and tell them to dispose of it properly 00:15:19.157 --> 00:15:22.323 because you don't want to have the responsibility of taking it home 00:15:22.323 --> 00:15:24.543 and having to do that anyway. 00:15:26.829 --> 00:15:29.966 But more importantly, we need to go back. 00:15:29.966 --> 00:15:36.148 We need to understand the systems that sustain life on planet Earth, 00:15:36.938 --> 00:15:39.126 like the bird and the worm. 00:15:39.126 --> 00:15:41.266 The bird wasn't committing murder. 00:15:41.266 --> 00:15:45.485 They're part of a greater ecological, environmental system 00:15:45.485 --> 00:15:47.196 which sustains life on Earth. 00:15:47.196 --> 00:15:48.378 I know that now. 00:15:48.378 --> 00:15:50.938 I didn't when I was five years of age. 00:15:50.938 --> 00:15:53.118 Just like eight years ago, 00:15:53.118 --> 00:15:58.029 I had no idea that by throwing my plastic products into the rubbish bin, 00:15:58.029 --> 00:16:00.026 I was damaging the environment, 00:16:00.027 --> 00:16:02.357 and I was polluting the food chain. 00:16:04.197 --> 00:16:07.387 Awareness is a very powerful tool. 00:16:07.756 --> 00:16:09.278 As I say in the film, 00:16:09.278 --> 00:16:14.387 "With knowing comes caring, and with caring comes change." 00:16:14.927 --> 00:16:17.486 And I'd like to leave you with this last thought: 00:16:18.638 --> 00:16:22.198 Change starts with each and every one of you. 00:16:23.536 --> 00:16:29.017 There is a need to change, and when that need arises, it's right now. 00:16:29.742 --> 00:16:32.328 So, we all need to start change 00:16:32.328 --> 00:16:36.598 for our future, for ourselves and for our children. 00:16:36.847 --> 00:16:38.386 Thank you very much. 00:16:38.386 --> 00:16:40.064 (Applause)
