0:00:00.722,0:00:04.212 We need to build[br]a weather service for water. 0:00:04.236,0:00:07.610 Yet, until we collectively[br]demand accountability, 0:00:07.634,0:00:10.470 the incentives to fund it will not exist. 0:00:11.805,0:00:16.744 The first time I spoke at a conference[br]was here at TED, eight years ago. 0:00:16.768,0:00:19.056 Fresh out of grad school,[br]little did I know 0:00:19.080,0:00:20.934 that in those few minutes onstage, 0:00:20.958,0:00:23.492 I was framing the questions[br]I was going to be asked 0:00:23.516,0:00:24.791 for the next decade. 0:00:25.599,0:00:28.111 And, like too many 20-somethings, 0:00:28.135,0:00:30.611 I expected to solve[br]the world's problems -- 0:00:30.635,0:00:33.387 more specifically,[br]the world's water problems -- 0:00:33.411,0:00:35.118 with my technology. 0:00:36.044,0:00:37.458 I had a lot to learn. 0:00:38.630,0:00:40.114 It was seductive, 0:00:40.138,0:00:44.470 believing that our biggest[br]water quality problems persist 0:00:44.494,0:00:46.947 because they're so hard to identify. 0:00:47.532,0:00:49.199 And I presumed 0:00:49.223,0:00:54.303 that we just needed simpler, faster[br]and more affordable sensors. 0:00:55.071,0:00:56.375 I was wrong. 0:00:57.512,0:01:01.635 While it's true that[br]managing tomorrow's water risk 0:01:01.659,0:01:05.729 is going to require better data[br]and more technology, 0:01:05.753,0:01:10.294 today we're barely using[br]the little water data that we have. 0:01:10.814,0:01:15.501 Our biggest water problems persist[br]because of what we don't do 0:01:15.525,0:01:18.502 and the problems we fail to acknowledge. 0:01:19.151,0:01:20.764 There's actually little question 0:01:20.788,0:01:25.635 about what today's water data[br]is telling us to do as a species: 0:01:25.659,0:01:27.443 we need to conserve more, 0:01:27.467,0:01:29.154 and we need to pollute less. 0:01:30.364,0:01:34.688 But today's data is not going to help us[br]forecast the emerging risks 0:01:34.712,0:01:36.924 facing businesses and markets. 0:01:36.948,0:01:40.015 It's rapidly becoming useless for that. 0:01:40.039,0:01:41.997 It used to carry more value, 0:01:42.021,0:01:46.016 but it's never actually told us[br]with any real accuracy 0:01:46.040,0:01:47.582 how much water we have 0:01:47.606,0:01:48.796 or what's in it. 0:01:49.899,0:01:54.282 Let's consider the past decade[br]of water usage statistics 0:01:54.306,0:01:56.532 from each of the G20 nations. 0:01:56.556,0:01:59.109 Now, what these numbers do not tell you 0:01:59.133,0:02:04.197 is that none of these countries[br]directly measures how much water they use. 0:02:04.221,0:02:05.505 These are all estimates, 0:02:05.529,0:02:08.152 and they're based on outdated models 0:02:08.176,0:02:11.010 that don't consider the climate crisis, 0:02:11.034,0:02:14.468 nor do they consider its impact on water. 0:02:16.037,0:02:20.079 In 2015, Chennai,[br]India's sixth-largest city, 0:02:20.103,0:02:23.485 was hit with the worst floods[br]it had seen in a century. 0:02:25.100,0:02:28.362 Today, its water reservoirs[br]are nearly dry. 0:02:28.862,0:02:31.864 It took three years to get here, 0:02:31.888,0:02:34.207 three years of subaverage rainfall. 0:02:34.231,0:02:38.941 Now, that's faster than most nations[br]tabulate their national water data, 0:02:38.965,0:02:40.488 including the US. 0:02:41.200,0:02:43.808 And although there were forecasts 0:02:43.832,0:02:48.064 that predicted severe shortages[br]of water in Chennai, 0:02:48.088,0:02:51.596 none of them could actually help us[br]pinpoint exactly when or where 0:02:51.620,0:02:53.118 this was going to happen. 0:02:53.536,0:02:56.577 This is a new type of water problem, 0:02:56.601,0:03:01.915 because the rate at which[br]every aspect of our water cycle changes 0:03:01.939,0:03:03.368 is accelerating. 0:03:03.392,0:03:06.717 As a recent UN warning[br]this month revealed, 0:03:06.741,0:03:12.006 we are now facing one new[br]climate emergency every single week. 0:03:14.089,0:03:17.320 There are greater uncertainties[br]ahead for water quality. 0:03:17.344,0:03:21.141 It's rare in most countries[br]for most water bodies to be tested 0:03:21.165,0:03:24.016 for more than a handful[br]of contaminants in a year. 0:03:24.040,0:03:27.201 Instead of testing, we use[br]what's called the "dilution model" 0:03:27.225,0:03:28.987 to manage pollution. 0:03:29.011,0:03:32.679 Now, imagine I took[br]an Olympic-sized swimming pool, 0:03:32.703,0:03:36.036 I filled it with fresh water[br]and I added one drop of mercury. 0:03:36.060,0:03:38.882 That would dilute down[br]to one part per billion mercury, 0:03:38.906,0:03:41.479 which is well within what[br]the World Health Organization 0:03:41.503,0:03:43.037 considers safe. 0:03:43.061,0:03:47.279 But if there was any unforeseen drop[br]in how much water was available -- 0:03:47.303,0:03:52.220 less groundwater, less stream flow,[br]less water in the pool -- 0:03:52.244,0:03:54.201 less dilution would take place, 0:03:54.225,0:03:56.428 and things would get more toxic. 0:03:57.049,0:04:00.414 So this is how most countries[br]are managing pollution. 0:04:00.438,0:04:03.757 They use this model to tell them[br]how much pollution is safe. 0:04:04.146,0:04:06.271 And it has clear weaknesses, 0:04:06.295,0:04:08.937 but it worked well enough[br]when we had abundant water 0:04:08.961,0:04:11.318 and consistent weather patterns. 0:04:11.751,0:04:15.787 Now that we don't, we're going to need[br]to invest and develop 0:04:15.811,0:04:18.137 new data-collection strategies. 0:04:18.161,0:04:22.236 But before we do that, we have to start[br]acting on the data we already have. 0:04:22.944,0:04:25.066 This is a jet fuel fire. 0:04:25.090,0:04:26.926 As many of you may be aware, 0:04:26.950,0:04:30.283 jet fuel emissions play[br]an enormous role in climate change. 0:04:30.307,0:04:33.941 What you might not be aware of[br]is that the US Department of Defense 0:04:33.965,0:04:36.748 is the world's largest[br]consumer of jet fuel. 0:04:36.772,0:04:38.502 And when they consume jet fuel, 0:04:38.526,0:04:42.552 they mandate the use[br]of the firefighting foam pictured here, 0:04:42.576,0:04:45.803 which contains a class[br]of chemicals called PFAS. 0:04:45.827,0:04:49.634 Nobody uses more of this foam[br]than the US Department of Defense, 0:04:49.658,0:04:54.102 and every time it's used, PFAS[br]finds its way into our water systems. 0:04:54.582,0:04:59.487 Globally, militaries have been using[br]this foam since the 1970s. 0:04:59.511,0:05:03.057 We know PFAS causes cancer, birth defects, 0:05:03.081,0:05:05.928 and it's now so pervasive[br]in the environment 0:05:05.952,0:05:10.238 that we seem to find it in nearly[br]every living thing we test, 0:05:10.262,0:05:11.724 including us. 0:05:13.073,0:05:17.235 But so far, the US Department of Defense[br]has not been held accountable 0:05:17.259,0:05:19.021 for PFAS contamination, 0:05:19.045,0:05:20.945 nor has it been held liable. 0:05:20.969,0:05:24.932 And although there's an effort underway[br]to phase out these firefighting foams, 0:05:24.956,0:05:28.469 they're not embracing safer,[br]effective alternatives. 0:05:28.493,0:05:31.330 They're actually using[br]other PFAS molecules, 0:05:31.354,0:05:36.565 which may, for all we know,[br]carry worse health consequences. 0:05:37.969,0:05:44.520 So today, government accountability[br]is eroding to the point of elimination, 0:05:44.544,0:05:49.343 and the risk of liability[br]from water pollution is vanishing. 0:05:50.029,0:05:54.370 What types of incentives does this create[br]for investing in our water future? 0:05:55.190,0:06:00.916 Over the past decade, the average[br]early stage global investment 0:06:00.940,0:06:03.367 in early stage water technology companies 0:06:03.391,0:06:06.173 has totaled less than[br]30 million dollars every year. 0:06:06.919,0:06:13.257 That's 0.12 percent of global[br]venture capital for early stage companies. 0:06:15.035,0:06:19.605 And public spending is not going up[br]nearly fast enough. 0:06:19.629,0:06:23.693 And a closer look at it reveals[br]that water is not a priority. 0:06:24.371,0:06:29.779 In 2014, the US federal government[br]was spending 11 dollars per citizen 0:06:29.803,0:06:31.693 on water infrastructure, 0:06:31.717,0:06:35.871 versus 251 dollars on IT infrastructure. 0:06:36.478,0:06:39.795 So when we don't use the data we have, 0:06:39.819,0:06:42.458 we don't encourage investment[br]in new technologies, 0:06:42.482,0:06:44.642 we don't encourage more data collection 0:06:44.666,0:06:49.677 and we certainly don't encourage[br]investment in securing a water future. 0:06:50.820,0:06:52.446 So are we doomed? 0:06:53.477,0:06:55.188 Part of what I'm still learning 0:06:55.212,0:07:00.334 is how to balance the doom[br]and the urgency with things we can do, 0:07:00.358,0:07:03.184 because Greta Thunberg[br]and the Extinction Rebellion 0:07:03.208,0:07:05.364 don't want our hope --[br]they want us to act. 0:07:05.388,0:07:06.935 So what can we do? 0:07:07.872,0:07:12.782 It's hard to imagine life[br]without a weather service, 0:07:12.806,0:07:15.121 but before modern weather forecasting, 0:07:15.145,0:07:17.196 we had no commercial air travel, 0:07:17.220,0:07:21.088 it was common for ships to be lost at sea, 0:07:21.112,0:07:24.388 and a single storm could produce[br]a food shortage. 0:07:25.460,0:07:27.896 Once we had radio and telegraph networks, 0:07:27.920,0:07:31.228 all that was necessary[br]to solve these problems 0:07:31.252,0:07:33.443 was tracking the movement of storms. 0:07:34.705,0:07:39.089 And that laid the foundation[br]for a global data collection effort, 0:07:39.113,0:07:43.324 one that every household[br]and every business depends upon today. 0:07:43.987,0:07:47.724 And this was as much the result of[br]coordinated and consistent data collection 0:07:47.748,0:07:53.155 as it was the result of producing[br]a culture that saw greater value 0:07:53.179,0:07:58.026 in openly assessing and sharing everything[br]that it could find out and discover 0:07:58.050,0:08:00.001 about the risks we face. 0:08:01.108,0:08:05.041 A global weather service for water[br]would help us forecast water shortages. 0:08:05.770,0:08:11.359 It could help us implement rationing[br]well before reservoirs run dry. 0:08:11.942,0:08:15.197 It could help us detect[br]contamination before it spreads. 0:08:15.221,0:08:17.601 It could protect our supply chains, 0:08:17.625,0:08:19.479 secure our food supplies, 0:08:19.503,0:08:21.149 and, perhaps most importantly, 0:08:21.173,0:08:24.611 it would enable[br]the precise estimation of risk 0:08:24.635,0:08:27.376 necessary to insure against it. 0:08:28.062,0:08:31.259 We know we can do this because[br]we've already done it with weather. 0:08:31.283,0:08:33.580 But it's going to require resources. 0:08:34.683,0:08:37.489 We need to encourage[br]greater investment in water. 0:08:37.513,0:08:39.625 Investors, venture capitalists: 0:08:39.649,0:08:43.372 a portion of your funds and portfolios[br]should be dedicated to water. 0:08:43.715,0:08:45.259 Nothing is more valuable 0:08:45.283,0:08:49.054 and, after all, businesses are going[br]to need to understand water risks 0:08:49.078,0:08:52.462 in order to remain competitive[br]in the world we are entering. 0:08:53.220,0:08:55.455 Aside from venture capital, 0:08:55.479,0:08:58.758 there are also lots of promising[br]government programs 0:08:58.782,0:09:02.272 that encourage economic development[br]through tax incentives. 0:09:02.665,0:09:05.494 A new option in the US[br]that my company is using 0:09:05.518,0:09:07.107 is called "opportunity zones." 0:09:07.651,0:09:11.557 They offer favorable tax treatment[br]for investing capital gains 0:09:11.581,0:09:14.916 in designated distressed[br]and low-income areas. 0:09:14.940,0:09:16.737 Now, these are areas 0:09:16.761,0:09:19.375 that are also facing[br]staggering water risk, 0:09:19.399,0:09:22.952 so this creates crucial incentives[br]to work directly with the communities 0:09:22.976,0:09:24.756 who need help most. 0:09:24.780,0:09:29.107 And if you're not looking[br]to make this type of investment 0:09:29.131,0:09:30.660 but you own land in the US, 0:09:30.684,0:09:34.238 did you know that[br]you can leverage your land 0:09:34.262,0:09:37.177 to conserve water quality permanently 0:09:37.201,0:09:39.218 with a conservation easement? 0:09:39.242,0:09:42.851 You can assign the perpetual right[br]to a local land trust 0:09:42.875,0:09:44.488 to conserve your land 0:09:44.512,0:09:46.446 and set specific water quality goals. 0:09:46.470,0:09:48.180 And if you meet those goals, 0:09:48.204,0:09:52.562 you can be rewarded with[br]a substantial tax discount every year. 0:09:54.435,0:09:58.845 How many areas could[br]our global community protect 0:09:58.869,0:10:01.475 through these and other programs? 0:10:02.435,0:10:05.918 They're powerful because they offer[br]the access to real property 0:10:05.942,0:10:10.131 necessary to lay the foundation[br]for a global weather service for water. 0:10:11.020,0:10:16.755 But this can only work if we use[br]these programs as they are intended 0:10:16.779,0:10:20.066 and not as mere vehicles for tax evasion. 0:10:21.072,0:10:23.333 When the conservation easement[br]was established, 0:10:23.357,0:10:26.615 nobody could anticipate how ingrained[br]in environmental movements 0:10:26.639,0:10:28.917 corporate polluters would become. 0:10:28.941,0:10:33.652 And we've become accustomed to companies[br]talking about the climate crisis 0:10:33.676,0:10:36.048 while doing nothing about it. 0:10:37.738,0:10:42.379 This has undermined the legacy[br]and the impact of these programs, 0:10:42.403,0:10:45.085 but it also makes them[br]ripe for reclamation. 0:10:45.109,0:10:48.207 Why not use conservation easements[br]as they were intended, 0:10:48.231,0:10:52.581 to set and reach[br]ambitious conservation goals? 0:10:52.605,0:10:56.908 Why not create opportunities[br]in opportunity zones? 0:10:57.456,0:11:01.826 Because fundamentally,[br]water security requires accountability. 0:11:02.444,0:11:08.162 Accountability is not corporate polluters[br]sponsoring environmental groups 0:11:08.186,0:11:09.995 and museums. 0:11:10.019,0:11:12.059 Those are conflicts of interest. 0:11:12.083,0:11:17.204 (Applause) 0:11:18.126,0:11:20.205 Accountability is: 0:11:21.143,0:11:25.403 making the risk of liability too expensive 0:11:25.427,0:11:28.405 to continue polluting[br]and wasting our water. 0:11:28.429,0:11:32.209 We can't keep settling for words.[br]It's time to act. 0:11:32.233,0:11:35.701 And where better to start[br]than with our biggest polluters, 0:11:35.725,0:11:40.804 particularly the US Department[br]of Defense, which is taxpayer-funded. 0:11:40.828,0:11:44.501 Who and what are we protecting[br]when US soldiers, their families 0:11:44.525,0:11:48.012 and the people who live near[br]US military bases abroad 0:11:48.036,0:11:50.308 are all drinking toxic water? 0:11:50.876,0:11:55.323 Global security can no longer remain[br]at odds with protecting our planet 0:11:55.347,0:11:56.787 or our collective health. 0:11:56.811,0:11:58.958 Our survival depends on it. 0:11:59.404,0:12:00.554 Similarly, 0:12:01.178,0:12:05.054 agriculture in most countries[br]depends on taxpayer-funded subsidies 0:12:05.078,0:12:08.945 that are paid to farmers to secure[br]and stabilize food supplies. 0:12:10.039,0:12:14.417 These incentives are[br]a crucial leverage point for us, 0:12:14.441,0:12:18.971 because agriculture is responsible[br]for consuming 70 percent 0:12:18.995,0:12:21.353 of all the water we use every year. 0:12:22.061,0:12:24.713 Fertilizer and pesticide runoff 0:12:24.737,0:12:27.436 are the two biggest sources[br]of water pollution. 0:12:27.460,0:12:31.225 Let's restructure these subsidies[br]to demand better water efficiency 0:12:31.249,0:12:32.971 and less pollution. 0:12:32.995,0:12:38.105 (Applause) 0:12:38.740,0:12:40.199 Finally: 0:12:40.223,0:12:41.695 we can't expect progress 0:12:41.719,0:12:44.597 if we're unwilling to confront[br]the conflicts of interest 0:12:44.621,0:12:46.478 that suppress science, 0:12:46.502,0:12:48.450 that undermine innovation 0:12:48.474,0:12:50.932 and that discourage transparency. 0:12:50.956,0:12:52.756 It is in the public interest 0:12:52.780,0:12:56.728 to measure and to share everything[br]we can learn and discover 0:12:56.752,0:12:59.341 about the risks we face in water. 0:12:59.881,0:13:03.451 Reality does not exist[br]until it's measured. 0:13:03.475,0:13:07.274 It doesn't just take[br]technology to measure it. 0:13:07.298,0:13:09.177 It takes our collective will. 0:13:09.201,0:13:10.535 Thank you.
