Transcript for Ginger Zee reports live from one of the world's largest waterfalls
It's a big morning here. We've been talking about this all morning and we've been exploring some of Earth's amazing -- most amazing places and why it's so important to take care of them. This could be the most exciting yet all the way to Argentina. The spectacular waterfalls at iguazu national park. How is it going? Buenos dias. Welcome to Argentina and Brazil right between them and these are iguazu falls. I am telling you I am still in awe and apparently not alone. Eleanor rose set when she first came here said niagara. Their majesty, not the only reason we're here. With Netflix celebrating their original series "Our planet" that premieres today we are actually looking at the vital role that fresh water plays. All of this fresh water plus the rain forest around us that happens to be one of the most threatened on the planet. ������ majestic, magical. Mighty. Cascading walls of water as far as the eye can see. Straddling the border of Argentina and Brazil iguazu is made up of an astonishing 275 waterfalls sponsored in Netflix's "Our planet" voiced by sir David attenborough. These are the largest waterfalls on the planet. Thousands of tons of fresh water thunder over them every second. What makes the waterfall so special? Over there you feel very small. And it's mesmerizing. ������ let me introduce you to this beast behind me. It is devil's throat. The tallest of the waterwalls here at iguazu dropping 262 feet into a milky white abyss. Iguazu is surrounded by the atlantic rain forest. This forest and the rest of the forests in South America are not only helping to pry fresh water but the oxygen we all breathe so we rely on them being healthy and the forest being intact. Reporter: Teeming with 2,000 species of plants and animals including the raccoon like cuoati and native birds before swooping straight into the falls. What we're trying to do with our planet is take people to these incredible landscapes and habitats and show people that aren't able to come here the value of these systems. Through the rain forest more than a million visitors come to iguazu falls and walk these footbridges so they can access views like this. And along the river, the ultimate adventure. A boat ride feeling the strength of the falls. In this place that reminds us of the beauty of our planet. So let me give you just a little more perspective. The atlantic forests are the rain forests that encases the waterfalls. There's actually own 10% of it left, of the original because of deforestation so why should you care about that? Each one of those trees puts off water vapor. That makes a cloud. That transports water and fresh water around the globe. It's meteorology. That atmospheric river I tell you about all the time. That plus a quarter of all the oxygen we breathe comes from trees ondz land and plant and the biodiversity, that fragile ecosystem surrounding us so I have to say if that isn't inspiring enough, perhaps me going into the waterfall will inspire you to keep these jewels of our planet safe so that's what we're going to do coming up. I'm going in San Martine, the big one right here, it's been raining all morning so I'm soaked but we're about to get a whole lot more soaked. I tell you what, the images are beautifully and definitely needs to be preserved. We're so glad ginger is brave enough to go in there. Can't wait for the big live event when she goes under the falls. That's happening when we come
