Boyan Slat: How we will rid the oceans of plastic (May 2017)

that if during the last two years there was an even better way to clear the ocean, we worked on what would make this possible, and we show that you look as if you haven’t seen anything before, and I’m so glad that we finally we can share this with you here tonight, but before we return to the answer, let’s go back and ask ourselves why it is so important that we manage to clear the oceans of plastic, therefore there are five areas in the world where ocean currents concentrate plastic and the biggest of these clusters is sad the famous Great Pacific Garbage Patch, which is halfway between Hawaii and California, and here is a graph showing the plastic concentration in this gray Pacific garbage patch starting in, say, the 1950s, 1960s, on the left. just recently, and I think that this is the only image that shows what the essence is deteriorating quickly, and in fact this is not the only thing that we can see from this graph, we also see that the plastic accumulates it remains there, and this is a very important observation, because it means that in fact the only way to make this line go down again is to actually go there and clean it, it simply will not disappear by itself, it is persevering and illustrate this Accuracy of the vision. I gave a few examples of the one and a half million pieces that we pulled out of the ocean last year, so let’s start with this, so it may look like a random piece of plastic, but actually this is the back side of the mini Gameboy, and if you look at it carefully , you can see what is written on it in Nintendo 1995, so this piece of plastic, in essence, is all desire, and here, in fact, here is my photo in the 95th. I obviously don’t look at it anymore, at least I hope it’s clear, but after two decades this piece of plastic remains relatively unchanged, now let’s go back even further in time for 1989. You may remember it as the year of the fall of the Berlin Wall, but in fact it was not the only thing that happened that year, no, it was also the year when somewhere in Japan this helmet was made now and do not forget business things. that we pulled out of the ocean last year, so these are pretty recent things, and I can get even older than we see. Here is a box that apparently was used to store bottles of soft drinks, and if you look at the date on it, you will see that 1977 is written on it, so this thing is 40 le t, and 40 years is 1977, when Elvis Presley apparently left creation for good, and 1937 was also a year for my fellows, the year when Jobs was presented the original Apple 2 in the computer case on the West Coast, and then, when you look at these tiny pieces of microplastic in a circle, we estimate that they could have been large objects when they entered the oceans in which they were in the 50s or 60s, but because of sunlight plastic becomes more fragile after decades, and then it begins to break up into these little e, but very dangerous fragments, dangerous because of the tents of this dish are the actual contents of the stomach of one individual, so it was found dead in Oregon last year, so the plastic not only remains in the ocean, but also becomes more harmful over time, and frankly, it scares the memo, because now, in accordance with our latest data on the advancement of expeditions, that we have done only about 3% of plastic, these are slow pieces, but most of them are still locked in the way of loading in these big objects because that, of course, what will happen in the next few decades, when all these large objects begin to disintegrate into these small and dangerous microplastics, and also increase the number of microplastics tenfold, if we do not clear them, we must disperse this time bomb, and this It has been my mission ever since I found cleaning the ocean four years ago, a lot has happened in these four years, and it all started with one simple idea: instead of using plastic, we let the plastic come to us, saving at time. ergonomics and cost, using natural ocean currents to our advantage, we can allow the ocean to self-clean. I imagine a network of extremely long floating screens that would first concentrate plastic so that we can then remove it, save it, before sending it to land. for recycling, and therefore the idea was to use a closed screen instead of Nets networks, we could avoid Scylla’s by-catch, and then we showed that in one 100-kilometer stream we could clean up about 42% of this Great Pacific garbage can in only 10 years back, but to make this dream a reality, we first needed some funding, so we made this small crowdfunding campaign for those who support
