WEBVTT 00:00:00.722 --> 00:00:04.212 We need to build a weather service for water. 00:00:04.236 --> 00:00:07.610 Yet, until we collectively demand accountability, 00:00:07.634 --> 00:00:10.470 the incentives to fund it will not exist. NOTE Paragraph 00:00:11.805 --> 00:00:16.744 The first time I spoke at a conference was here at TED, eight years ago. 00:00:16.768 --> 00:00:19.056 Fresh out of grad school, little did I know 00:00:19.080 --> 00:00:20.934 that in those few minutes onstage, 00:00:20.958 --> 00:00:23.492 I was framing the questions I was going to be asked 00:00:23.516 --> 00:00:24.791 for the next decade. 00:00:25.599 --> 00:00:28.111 And, like too many 20-somethings, 00:00:28.135 --> 00:00:30.611 I expected to solve the world's problems -- 00:00:30.635 --> 00:00:33.387 more specifically, the world's water problems -- 00:00:33.411 --> 00:00:35.118 with my technology. 00:00:36.044 --> 00:00:37.458 I had a lot to learn. NOTE Paragraph 00:00:38.630 --> 00:00:40.114 It was seductive, 00:00:40.138 --> 00:00:44.470 believing that our biggest water quality problems persist 00:00:44.494 --> 00:00:46.947 because they're so hard to identify. 00:00:47.532 --> 00:00:49.199 And I presumed 00:00:49.223 --> 00:00:54.303 that we just needed simpler, faster and more affordable sensors. 00:00:55.071 --> 00:00:56.375 I was wrong. 00:00:57.512 --> 00:01:01.635 While it's true that managing tomorrow's water risk 00:01:01.659 --> 00:01:05.729 is going to require better data and more technology, 00:01:05.753 --> 00:01:10.294 today we're barely using the little water data that we have. 00:01:10.814 --> 00:01:15.501 Our biggest water problems persist because of what we don't do 00:01:15.525 --> 00:01:18.502 and the problems we fail to acknowledge. 00:01:19.151 --> 00:01:20.764 There's actually little question 00:01:20.788 --> 00:01:25.635 about what today's water data is telling us to do as a species: 00:01:25.659 --> 00:01:27.443 we need to conserve more, 00:01:27.467 --> 00:01:29.154 and we need to pollute less. 00:01:30.364 --> 00:01:34.688 But today's data is not going to help us forecast the emerging risks 00:01:34.712 --> 00:01:36.924 facing businesses and markets. 00:01:36.948 --> 00:01:40.015 It's rapidly becoming useless for that. 00:01:40.039 --> 00:01:41.997 It used to carry more value, 00:01:42.021 --> 00:01:46.016 but it's never actually told us with any real accuracy 00:01:46.040 --> 00:01:47.582 how much water we have 00:01:47.606 --> 00:01:48.796 or what's in it. NOTE Paragraph 00:01:49.899 --> 00:01:54.282 Let's consider the past decade of water usage statistics 00:01:54.306 --> 00:01:56.532 from each of the G20 nations. 00:01:56.556 --> 00:01:59.109 Now, what these numbers do not tell you 00:01:59.133 --> 00:02:04.197 is that none of these countries directly measures how much water they use. 00:02:04.221 --> 00:02:05.505 These are all estimates, 00:02:05.529 --> 00:02:08.152 and they're based on outdated models 00:02:08.176 --> 00:02:11.010 that don't consider the climate crisis, 00:02:11.034 --> 00:02:14.468 nor do they consider its impact on water. NOTE Paragraph 00:02:16.037 --> 00:02:20.079 In 2015, Chennai, India's sixth-largest city, 00:02:20.103 --> 00:02:23.485 was hit with the worst floods it had seen in a century. 00:02:25.100 --> 00:02:28.362 Today, its water reservoirs are nearly dry. 00:02:28.862 --> 00:02:31.864 It took three years to get here, 00:02:31.888 --> 00:02:34.207 three years of subaverage rainfall. 00:02:34.231 --> 00:02:38.941 Now, that's faster than most nations tabulate their national water data, 00:02:38.965 --> 00:02:40.488 including the US. 00:02:41.200 --> 00:02:43.808 And although there were forecasts 00:02:43.832 --> 00:02:48.064 that predicted severe shortages of water in Chennai, 00:02:48.088 --> 00:02:51.596 none of them could actually help us pinpoint exactly when or where 00:02:51.620 --> 00:02:53.118 this was going to happen. 00:02:53.536 --> 00:02:56.577 This is a new type of water problem, 00:02:56.601 --> 00:03:01.915 because the rate at which every aspect of our water cycle changes 00:03:01.939 --> 00:03:03.368 is accelerating. 00:03:03.392 --> 00:03:06.717 As a recent UN warning this month revealed, 00:03:06.741 --> 00:03:12.006 we are now facing one new climate emergency every single week. NOTE Paragraph 00:03:14.089 --> 00:03:17.320 There are greater uncertainties ahead for water quality. 00:03:17.344 --> 00:03:21.141 It's rare in most countries for most water bodies to be tested 00:03:21.165 --> 00:03:24.016 for more than a handful of contaminants in a year. 00:03:24.040 --> 00:03:27.201 Instead of testing, we use what's called the "dilution model" 00:03:27.225 --> 00:03:28.987 to manage pollution. 00:03:29.011 --> 00:03:32.679 Now, imagine I took an Olympic-sized swimming pool, 00:03:32.703 --> 00:03:36.036 I filled it with fresh water and I added one drop of mercury. 00:03:36.060 --> 00:03:38.882 That would dilute down to one part per billion mercury, 00:03:38.906 --> 00:03:41.479 which is well within what the World Health Organization 00:03:41.503 --> 00:03:43.037 considers safe. 00:03:43.061 --> 00:03:47.279 But if there was any unforeseen drop in how much water was available -- 00:03:47.303 --> 00:03:52.220 less groundwater, less stream flow, less water in the pool -- 00:03:52.244 --> 00:03:54.201 less dilution would take place, 00:03:54.225 --> 00:03:56.428 and things would get more toxic. 00:03:57.049 --> 00:04:00.414 So this is how most countries are managing pollution. 00:04:00.438 --> 00:04:03.757 They use this model to tell them how much pollution is safe. 00:04:04.146 --> 00:04:06.271 And it has clear weaknesses, 00:04:06.295 --> 00:04:08.937 but it worked well enough when we had abundant water 00:04:08.961 --> 00:04:11.318 and consistent weather patterns. 00:04:11.751 --> 00:04:15.787 Now that we don't, we're going to need to invest and develop 00:04:15.811 --> 00:04:18.137 new data-collection strategies. 00:04:18.161 --> 00:04:22.236 But before we do that, we have to start acting on the data we already have. NOTE Paragraph 00:04:22.944 --> 00:04:25.066 This is a jet fuel fire. 00:04:25.090 --> 00:04:26.926 As many of you may be aware, 00:04:26.950 --> 00:04:30.283 jet fuel emissions play an enormous role in climate change. 00:04:30.307 --> 00:04:33.941 What you might not be aware of is that the US Department of Defense 00:04:33.965 --> 00:04:36.748 is the world's largest consumer of jet fuel. 00:04:36.772 --> 00:04:38.502 And when they consume jet fuel, 00:04:38.526 --> 00:04:42.552 they mandate the use of the firefighting foam pictured here, 00:04:42.576 --> 00:04:45.803 which contains a class of chemicals called PFAS. 00:04:45.827 --> 00:04:49.634 Nobody uses more of this foam than the US Department of Defense, 00:04:49.658 --> 00:04:54.102 and every time it's used, PFAS finds its way into our water systems. 00:04:54.582 --> 00:04:59.487 Globally, militaries have been using this foam since the 1970s. 00:04:59.511 --> 00:05:03.057 We know PFAS causes cancer, birth defects, 00:05:03.081 --> 00:05:05.928 and it's now so pervasive in the environment 00:05:05.952 --> 00:05:10.238 that we seem to find it in nearly every living thing we test, 00:05:10.262 --> 00:05:11.724 including us. 00:05:13.073 --> 00:05:17.235 But so far, the US Department of Defense has not been held accountable 00:05:17.259 --> 00:05:19.021 for PFAS contamination, 00:05:19.045 --> 00:05:20.945 nor has it been held liable. 00:05:20.969 --> 00:05:24.932 And although there's an effort underway to phase out these firefighting foams, 00:05:24.956 --> 00:05:28.469 they're not embracing safer, effective alternatives. 00:05:28.493 --> 00:05:31.330 They're actually using other PFAS molecules, 00:05:31.354 --> 00:05:36.565 which may, for all we know, carry worse health consequences. NOTE Paragraph 00:05:37.969 --> 00:05:44.520 So today, government accountability is eroding to the point of elimination, 00:05:44.544 --> 00:05:49.343 and the risk of liability from water pollution is vanishing. 00:05:50.029 --> 00:05:54.370 What types of incentives does this create for investing in our water future? 00:05:55.190 --> 00:06:00.916 Over the past decade, the average early stage global investment 00:06:00.940 --> 00:06:03.367 in early stage water technology companies 00:06:03.391 --> 00:06:06.173 has totaled less than 30 million dollars every year. 00:06:06.919 --> 00:06:13.257 That's 0.12 percent of global venture capital for early stage companies. 00:06:15.035 --> 00:06:19.605 And public spending is not going up nearly fast enough. 00:06:19.629 --> 00:06:23.693 And a closer look at it reveals that water is not a priority. 00:06:24.371 --> 00:06:29.779 In 2014, the US federal government was spending 11 dollars per citizen 00:06:29.803 --> 00:06:31.693 on water infrastructure, 00:06:31.717 --> 00:06:35.871 versus 251 dollars on IT infrastructure. 00:06:36.478 --> 00:06:39.795 So when we don't use the data we have, 00:06:39.819 --> 00:06:42.458 we don't encourage investment in new technologies, 00:06:42.482 --> 00:06:44.642 we don't encourage more data collection 00:06:44.666 --> 00:06:49.677 and we certainly don't encourage investment in securing a water future. NOTE Paragraph 00:06:50.820 --> 00:06:52.446 So are we doomed? 00:06:53.477 --> 00:06:55.188 Part of what I'm still learning 00:06:55.212 --> 00:07:00.334 is how to balance the doom and the urgency with things we can do, 00:07:00.358 --> 00:07:03.184 because Greta Thunberg and the Extinction Rebellion 00:07:03.208 --> 00:07:05.364 don't want our hope -- they want us to act. NOTE Paragraph 00:07:05.388 --> 00:07:06.935 So what can we do? 00:07:07.872 --> 00:07:12.782 It's hard to imagine life without a weather service, 00:07:12.806 --> 00:07:15.121 but before modern weather forecasting, 00:07:15.145 --> 00:07:17.196 we had no commercial air travel, 00:07:17.220 --> 00:07:21.088 it was common for ships to be lost at sea, 00:07:21.112 --> 00:07:24.388 and a single storm could produce a food shortage. 00:07:25.460 --> 00:07:27.896 Once we had radio and telegraph networks, 00:07:27.920 --> 00:07:31.228 all that was necessary to solve these problems 00:07:31.252 --> 00:07:33.443 was tracking the movement of storms. 00:07:34.705 --> 00:07:39.089 And that laid the foundation for a global data collection effort, 00:07:39.113 --> 00:07:43.324 one that every household and every business depends upon today. 00:07:43.987 --> 00:07:47.724 And this was as much the result of coordinated and consistent data collection 00:07:47.748 --> 00:07:53.155 as it was the result of producing a culture that saw greater value 00:07:53.179 --> 00:07:58.026 in openly assessing and sharing everything that it could find out and discover 00:07:58.050 --> 00:08:00.001 about the risks we face. NOTE Paragraph 00:08:01.108 --> 00:08:05.041 A global weather service for water would help us forecast water shortages. 00:08:05.770 --> 00:08:11.359 It could help us implement rationing well before reservoirs run dry. 00:08:11.942 --> 00:08:15.197 It could help us detect contamination before it spreads. 00:08:15.221 --> 00:08:17.601 It could protect our supply chains, 00:08:17.625 --> 00:08:19.479 secure our food supplies, 00:08:19.503 --> 00:08:21.149 and, perhaps most importantly, 00:08:21.173 --> 00:08:24.611 it would enable the precise estimation of risk 00:08:24.635 --> 00:08:27.376 necessary to insure against it. NOTE Paragraph 00:08:28.062 --> 00:08:31.259 We know we can do this because we've already done it with weather. 00:08:31.283 --> 00:08:33.580 But it's going to require resources. 00:08:34.683 --> 00:08:37.489 We need to encourage greater investment in water. 00:08:37.513 --> 00:08:39.625 Investors, venture capitalists: 00:08:39.649 --> 00:08:43.372 a portion of your funds and portfolios should be dedicated to water. 00:08:43.715 --> 00:08:45.259 Nothing is more valuable 00:08:45.283 --> 00:08:49.054 and, after all, businesses are going to need to understand water risks 00:08:49.078 --> 00:08:52.462 in order to remain competitive in the world we are entering. 00:08:53.220 --> 00:08:55.455 Aside from venture capital, 00:08:55.479 --> 00:08:58.758 there are also lots of promising government programs 00:08:58.782 --> 00:09:02.272 that encourage economic development through tax incentives. NOTE Paragraph 00:09:02.665 --> 00:09:05.494 A new option in the US that my company is using 00:09:05.518 --> 00:09:07.107 is called "opportunity zones." 00:09:07.651 --> 00:09:11.557 They offer favorable tax treatment for investing capital gains 00:09:11.581 --> 00:09:14.916 in designated distressed and low-income areas. 00:09:14.940 --> 00:09:16.737 Now, these are areas 00:09:16.761 --> 00:09:19.375 that are also facing staggering water risk, 00:09:19.399 --> 00:09:22.952 so this creates crucial incentives to work directly with the communities 00:09:22.976 --> 00:09:24.756 who need help most. NOTE Paragraph 00:09:24.780 --> 00:09:29.107 And if you're not looking to make this type of investment 00:09:29.131 --> 00:09:30.660 but you own land in the US, 00:09:30.684 --> 00:09:34.238 did you know that you can leverage your land 00:09:34.262 --> 00:09:37.177 to conserve water quality permanently 00:09:37.201 --> 00:09:39.218 with a conservation easement? 00:09:39.242 --> 00:09:42.851 You can assign the perpetual right to a local land trust 00:09:42.875 --> 00:09:44.488 to conserve your land 00:09:44.512 --> 00:09:46.446 and set specific water quality goals. 00:09:46.470 --> 00:09:48.180 And if you meet those goals, 00:09:48.204 --> 00:09:52.562 you can be rewarded with a substantial tax discount every year. NOTE Paragraph 00:09:54.435 --> 00:09:58.845 How many areas could our global community protect 00:09:58.869 --> 00:10:01.475 through these and other programs? 00:10:02.435 --> 00:10:05.918 They're powerful because they offer the access to real property 00:10:05.942 --> 00:10:10.131 necessary to lay the foundation for a global weather service for water. 00:10:11.020 --> 00:10:16.755 But this can only work if we use these programs as they are intended 00:10:16.779 --> 00:10:20.066 and not as mere vehicles for tax evasion. 00:10:21.072 --> 00:10:23.333 When the conservation easement was established, 00:10:23.357 --> 00:10:26.615 nobody could anticipate how ingrained in environmental movements 00:10:26.639 --> 00:10:28.917 corporate polluters would become. 00:10:28.941 --> 00:10:33.652 And we've become accustomed to companies talking about the climate crisis 00:10:33.676 --> 00:10:36.048 while doing nothing about it. 00:10:37.738 --> 00:10:42.379 This has undermined the legacy and the impact of these programs, 00:10:42.403 --> 00:10:45.085 but it also makes them ripe for reclamation. 00:10:45.109 --> 00:10:48.207 Why not use conservation easements as they were intended, 00:10:48.231 --> 00:10:52.581 to set and reach ambitious conservation goals? 00:10:52.605 --> 00:10:56.908 Why not create opportunities in opportunity zones? 00:10:57.456 --> 00:11:01.826 Because fundamentally, water security requires accountability. 00:11:02.444 --> 00:11:08.162 Accountability is not corporate polluters sponsoring environmental groups 00:11:08.186 --> 00:11:09.995 and museums. 00:11:10.019 --> 00:11:12.059 Those are conflicts of interest. NOTE Paragraph 00:11:12.083 --> 00:11:17.204 (Applause) NOTE Paragraph 00:11:18.126 --> 00:11:20.205 Accountability is: 00:11:21.143 --> 00:11:25.403 making the risk of liability too expensive 00:11:25.427 --> 00:11:28.405 to continue polluting and wasting our water. 00:11:28.429 --> 00:11:32.209 We can't keep settling for words. It's time to act. 00:11:32.233 --> 00:11:35.701 And where better to start than with our biggest polluters, 00:11:35.725 --> 00:11:40.804 particularly the US Department of Defense, which is taxpayer-funded. 00:11:40.828 --> 00:11:44.501 Who and what are we protecting when US soldiers, their families 00:11:44.525 --> 00:11:48.012 and the people who live near US military bases abroad 00:11:48.036 --> 00:11:50.308 are all drinking toxic water? 00:11:50.876 --> 00:11:55.323 Global security can no longer remain at odds with protecting our planet 00:11:55.347 --> 00:11:56.787 or our collective health. 00:11:56.811 --> 00:11:58.958 Our survival depends on it. NOTE Paragraph 00:11:59.404 --> 00:12:00.554 Similarly, 00:12:01.178 --> 00:12:05.054 agriculture in most countries depends on taxpayer-funded subsidies 00:12:05.078 --> 00:12:08.945 that are paid to farmers to secure and stabilize food supplies. 00:12:10.039 --> 00:12:14.417 These incentives are a crucial leverage point for us, 00:12:14.441 --> 00:12:18.971 because agriculture is responsible for consuming 70 percent 00:12:18.995 --> 00:12:21.353 of all the water we use every year. 00:12:22.061 --> 00:12:24.713 Fertilizer and pesticide runoff 00:12:24.737 --> 00:12:27.436 are the two biggest sources of water pollution. 00:12:27.460 --> 00:12:31.225 Let's restructure these subsidies to demand better water efficiency 00:12:31.249 --> 00:12:32.971 and less pollution. NOTE Paragraph 00:12:32.995 --> 00:12:38.105 (Applause) NOTE Paragraph 00:12:38.740 --> 00:12:40.199 Finally: 00:12:40.223 --> 00:12:41.695 we can't expect progress 00:12:41.719 --> 00:12:44.597 if we're unwilling to confront the conflicts of interest 00:12:44.621 --> 00:12:46.478 that suppress science, 00:12:46.502 --> 00:12:48.450 that undermine innovation 00:12:48.474 --> 00:12:50.932 and that discourage transparency. 00:12:50.956 --> 00:12:52.756 It is in the public interest 00:12:52.780 --> 00:12:56.728 to measure and to share everything we can learn and discover 00:12:56.752 --> 00:12:59.341 about the risks we face in water. 00:12:59.881 --> 00:13:03.451 Reality does not exist until it's measured. 00:13:03.475 --> 00:13:07.274 It doesn't just take technology to measure it. 00:13:07.298 --> 00:13:09.177 It takes our collective will.
