Number one in just sixty reporter good evening. Thank you for joining us. Some call it heaven on earth in the middle of the ocean. The galapagos, home to some of the most diverse species in the world and birthplace of darwins theory of evolution. Now threatened by its own popularity with tourists and a rising tide of trash. Abcs maggie rulli is on an expedition there. Reporter staggering, exquisite, and remote. The islands that inspired darwins survival of the fittest could be facing a fight for their survival the galapagos. One of the few places to see nature up close and personal is now being challenged by its own popularity. 21st century threats like bucket list tourism and plastic pollution are threatening the very existence of some of the islands most iconic animals. The beloved giant tortoises, blue footed boobies, and iguanas. And nearly everywhere you go, on a hike or a casual dip. Theres wildlife at your fingertips. The animals charm visitors making the appeal of the islands even greater. And look at this. Did it ever occur to you that sea lions love sleeping on benches . Oh, theyre snuggling in are you kidding me right now, t sea lions, theyre just like us. Its amazing how they prefer to live here in the town with the human they have the whole island but reporter they come up here they are sleeping here in the pier, theyre looking for nice boats just to rest. Reporter Federico Idrovo is part of the islands plan to protect this land. Every visitor is required by law to hire a state sanctioned naturalist like him for all island visits. With 775 naturalists for the more than a quarter of a million tourists who visited last year, these are coveted and highly competitive jobs. We are not allowed to eat here on this island. Its a totally protected. If you need the bathroom, also please use it right now, we cannot use the bathrooms there. Please never go outside of the trail. Dont touch the animals. You can touch the vegetation but please dont destroy it. Reporter 29 year old federico is part ranger. Almost 70 of the plants that we have here, is endemics and native plants. Then we have this solitary egg. That is uncommon that we found it. Reporter hes also part cop. You guides are no joke. I got off the trail earlier and someone else yelled at me. Yeah because my job is not just to point you where is the iguana that is a salty bush, this is the blue sky. My job is to control that everybody has to be inside the trail. Nobody can eat here, please never take some souvenirs reporter we heard that repeatedly you can see that this beautiful and unusual beach is shining like. Can we bring it home . No we cannot bring anything from here those are Galapagos National park rules. Reporter the number of visitors growing exponentially from just 5,000 fifty years ago. Behind us now theres even a hawk, and you pointed out an iguana i know, theyre just sort of common for us. Reporter youre used to it by now, right we meet lisa from wisconsin and judy from california who are halfway through their fantastic expedition. How strict has your naturalist been with you in terms of making sure you dont get off the path. Very strict, yes. But thats a good thing. Its a good thing. Reporter the webers also love having a personal guide. Well, i thought it was awesome because were kind of an intellectual family that likes to learn so there obvious we have been peppering him with questions. So its been really nice. Theyre also focus on preservation and conserving the Natural Environment that exist around us. Its very unique. Reporter it sounds like youve always had this drive to conserve. Was there a moment when you thought, i want to be a naturalist . I have a lot of knowledge in my mind. I have a lot of experience in my heart. I feel a lot of passion, and i wanna share it. Reporter there is so much commotion going on right now. Wait, theyre kind of coming close to you. Yeah, its because the male is here. Reporter the male is here. Is this what happens . He just ruined the whole chill vibe of this place. Everybody was sleeping, but now the male is like, all right, wheres my females . Reporter but this is incredible. I mean, were just sitting here on this beach right now, and nature is happening all around us. There are sea lions everywhere, but they dont seem to care that were here. Well i think that is possible because we are living in a place where we are respecting a lot the animals inside of the galapagos. Reporter hi bud its the once in a lifetime thrill of these experiences that puts the region at risk. But its something the World Wildlife fund says can be managed. Hugo arnal is the former wwf for ecuador. Tourism is a double edged swords. It can be good, and it can be bad. So lets make sure that we manage tourism the best possible way, and we use tourism as a conservation tool. Conservation isnt a nine to five job. That night at home with federico we saw how naturalists are responsible for reporting everything they see. I des describe what what i saw, and what was good and wrong. So for example, sometime there is some people destroying vegetation. Sometimes i found families with dogs. Dogs are restricted because they can cause crosscontamination, and so can we. Reporter thats because each of the at least 14 islands here are so drastically different from one another. Geologically and in the kinds of plants and animals that live on them. The most important threat to biodiversity on islands is invasive species. Because of the long distances between the islands without tourism thered be no crosscontamination. We dont want to bring germs, insects, parasites from this island to another island. A threat taken so seriously, people must pass through bio security checks every time they visit a new island. Another unwelcome visitor from island to island is trash. When you come to experience the vast beauty of the galapagos, you probably dont stop to think about the enormous amount of trash that tourists and locals isndsra. Vege a most of all of latin america. Mario piu is the director of a local recycling plant. So this recycling center can help save the environment, save the wildlife here in the galapagos . [ speaking in Foreign Language ] reporter Juan Pablo Munoz and his family of thre try to live with as little waste as possible. Were trying to to live as as as less plastic that we can. For example, our toothbrushes are wooden. All the diapers that we use for her are reusable diapers that you can wash. You can see our fridge, you see things that are wrapped in plastic. Even though we are conscious, we we try to make the difference, but theres not theres no other options. As as you can see, we tried to have all the toys that are made by wood, you know, by glass. But theres some items that you cannot escape. Reporter juan pablo knows first hand whats at stake. The only ones that are gonna be more affected about this problem is is our kids. And the kids of our kids. Reporter a marine scientist at the Galapagos Science Center he showed us what alarms him the most. I am showing you a microplastic sample from the stomach content of a fish here in the galapagos. But if you look in deep, using the standard microscope, you will see microplastic in this sample. From the ocean, you dont need a microscope. As the wwf were eager for us to see. Every single thing that floats eventually have the potentiality to arrive here. In the past it was wood, now its plastic, you know . Reporter so where does all this plastic, all this trash come from . I mean, it comes from everywhere everywhere. Literally it can can comes from from the states. It can comes from from from europe, it can comes from japan, it comes in from everywhere. On land, the amount is multiplied. Reporter seeing it up close, you see just theres so many different types of trash in here, types of plastic. You have, like, a hard hat. Gasoline containers. Some type of bottling container. Plastic bottle, plastic bottle, plastic bottle. So bottles, thats pretty much roughly the 80 of the debris that you find in the galapagos, bottles. One way or another, plastics is forever, so even even though you do the best thing to recycle it, its gonna be a little bit of release of microplastics that is gonna end up in the air or in the ocean or reporter what is microplastics . I want to show you that. Reporter look. Oh, its like oh, you can see it coming off in the air even. Yeah, exactly. So i think you can make reporter ugh. You see this . Reporter yeah. So this this reporter you can see the dust of blue. Oh my gosh, look at your hand and thats the real problem. Thats something that we dont know how to avoid. Because we can easily clean this macro debris that we reporter but how do you clean up dust . Exactly. How do you clean dust . So the best thing to do is attack this problem from the source. Before it arrive here. Because once it arrive here, its probably too late to do something about it. Reporter how do you change the minds of people when weve all gotten so used to this disposable lifestyle . They need to see this they need i think thats important that the that everybody actually understand that the most pristine places in this planet are like this full of plastic. For the island often called the laboratory of evolution, the stakes have never been higher. Reporter why should people in the middle of america care about the galapagos . Theres no planet b, okay . And you have places in in the many Different Countries that are unique. That are fantastic. Places that are so beautiful and so important that that they go beyond the political boundaries. And galapagos is one of them. Politically, yes, galapagos belongs to ecuador. Emotionally and in terms of heritage, it belongs to the world.

The slow mo guys have been quickly gaining traction. Fusing science and tech in their mesmerizing videos. Here is nightlines ashan singh with this flashback. I sh you in the face with this giant water balloon and see what happens. Three, two, one reporter this isnt exactly what i signed up fo but smashing things is what these guys do for a living. Meet the slow mo guys. Gavin free and dan gruchy. Famous for making unbelievably slow motion videos of pretty much anything you can think of. What about you guys has gotten so many people to latch on . Film a lot of stuff that just like, oh, you see that everyday, but youve never seen it this slow. Reporter from smashing jello with a tennis racket. To jumping on a mousetrap covered trampoline. Theyre capturing movements framebyframe showing viewers footage otherwise impossible to see with the naked eye. Their often ridiculous stunts racking up billions of views and over 11 million subscribers on youtube. Like jackass, but slowed down. The duos been around since the beginning of youtube and nowadays theyre full blown Celebrities Making big bucks. Did you guys ever think this was gonna get this big . There was no chance that i thought it was gonna get this big. Cause that was seven years agoish. These would be unheard of numbers. Reporter tucked away in a small garage in austin texas, the slomo headquarters. Okay, now this is my domain. This is where the magic comes from. Reporter endless props. Odds and ends. Stuff that would normally be collecting dust, absolute gold for the slow mo guys. This is actually full of about 1000 mouse traps. Oh my god this is the 1000 mouse traps that you sat on. Reporter it all started back in london. Two blokes doing ordinary teenager things. I would just make videos with different friends and i sort of found dan and i had the best banter on screen. So when it came time to start the slow mo guys he was the clear choice, and ive regret it ever since. Yeah he has actually hes now im stuck with him. Reporter with gavins access to a rare phantom slow motion camera, and dans undeniable panache on screen, the then teenage duo could film videos unmatched at that time. The guy i worked with, he had the only two phantom cameras in the country at the time and i realized i was 17 or 18 years old with access to this super expensive, super rare camera and that put us at a nice advantage. Reporter the camera, a phantom flex 4k, can cost around 150k. It can shoot so powerfully slow that filming for just five seconds can result in 19 hours of footage. Most youtubers, oh, i didnt expect it to had no idea this would happen. But this was always the intent to actually become wellknown for doing slow motion. Its boomed into a major money maker.
