It's like to go and to see an action movie. You see, the fish is a big school of fish is moving, and then you see the corals and you're there and you're breathing and you can witness it. My name is Paula Rodriguez. I'm a professor and researcher at the University of Guadalajara on a National Geographic Explorer. My field of study are the coral reefs. All the roofs that were studying belongs to the central Mexican Pacific. What's corals, Plants, animals or rocks? It's like it's Ah, two. For one. It's an animal because it belongs to the animal kingdom. But this relation Siam Biotic with a microalgae, they provide them food for each other. The microbiology gives them the color, So when you see a coral that's brown, it's because the microalgae is brown. And if you see a pink, it's because the microalgae spink to study any coral reefs is interesting because they're like a sensors for everything. As you will know, the ribs are declining That's because of the climate change you may know about the bleaching. That's what happened on the Great Barrier Reef on Australia. Bleaching happens when they lose that microbiology on that bleaching make us the dead off the corals. If they are bleaching, that's a sign is because it's something happening on the sea on its something happening with the climate. It's not the normal temperature that I usedto. That's a stress condition. If the conditions they don't go better, they will lose all the microbiology. They will die eventually. The ocean acidification is the change off the water chemistry way doing today Good. Where the water becomes more acid on that cause a change off the pH on that causes stress. The corals. They will make sinner skeletons more fragile skeletons so that you're a kind of thunderstorms when they are more intense, can take the entire ecosystem. Okay, this is very but it does that one with climate change. The problem is that the stress events are becoming more intense and more frequent. We're trying to figure out if the corals will make it or not. These trips in Mexico are very interesting because they are more recile int and resistant that some other areas we have witnessed so we can see here the bleaching. But also we have seen them recovery. Some of them died, but most of them survive on for the next stress event. They resist more on. If they bleach, they die less. So we're trying to understand why they have this resistance. Most corals living crystal waters with temperatures always stable on Dhere, the central region off the Pacific. In Mexico, the temperatures can go up and down for degrees in one day Celsius. So that's not supposed to be the optimal for corals. And here they live that every day, so they are already stress. They live all the time by stress. So when another stressful condition comes, they say, Well, yeah, it's bad. We're going toe bleach, but they can cope. We do coral restoration. The restoration technique actually so basic at the sites where the coral are more resistant, on more resilient, and we're taking those fragments natural fragments. Two sides nearby, the corals, the branching corals, they reproduced by fragmentation. We look for the healthy fragments and then we look for a surface to put it with cable ties way said that there are fragments of opportunity. If they find somewhere to attach, they will grow there. What we're giving them is like an extra shot. We monitored the healthy ribs and we're also monitoring the ribs that were restoring right. Mhm. It's very important for the tourism. Thio, go and visit the ribs. That's an important income. If you're not careful, that can damage the corals on the rest of organisms. Eventually, too many people makes ah huge damage. The information that we are generating around all these trips there are helping for them. Local managers toe make actions. So the local people on the government, on us as a scientific approach way, work together to find a solution. How can I still get people there to enjoy the place, but without losing it? So we apply what it's called current capacity, that it's how many people can get there without damaging the site. First, some people were angry like, Why are you closing the area? We want to go there, but if you want to really enjoy the natural resources off them, you have to wait a little bit to the system to rest. It wasn't too late. We're going to do something to make this better on to make it last for you, your sons, your grandsons. So we're trying to go one step of time. So I think that's that's the best advice. Don't look at the disaster. Look at what mitigated disaster. These animals, these ecosystems don't think about the hurricane. Think about the beautiful coral reefs. E trying not to lose their ability. Thio get amazed.
