the swamps of Louisiana, nearly one million acres of flooded forest marshland and by use, where there are no roadways, no maps. Getting lost can mean death, but the secrets of the swamp are known to a select few. Most of the swampers are Cajuns, and for the last 250 years they've prospered, passing down the rules of survival from generation to generation. Because out here it's man versus beast. Troy and his team are determined that this is the year they will catch the beast known as Big Head. For days, they scanned the water for this monster size gator. Finally, their determination pays off. They catch a glimpse of the legendary big head, but shooting a gator in the open is extremely difficult. Alligators have only one weak spot on their entire body, a tiny quarter sized area in the back of the head. In order to kill this gator, Clint has to hit that exact spot. Shot goes wide, big head dives for deep water. When Andrew Stanton set out to make an animated Children's movie set in the ocean, all he needed was the perfect fish for his main character, combing through coffee table books on sea Life is I landed on a photo of two fish peeking out of in an enemy. It was so arresting, Stanton says. I had no idea what kind of fish they were, but I couldn't take my eyes off them. And as an entertainer, the fact that they were called clownfish, it was perfect. There's almost nothing more appealing than these little fish that want to play peekaboo with you. And so a star was born Nemo. In the last 50 years, a quiet but profound revolution has taken place. Ah, host of satellites now stand watch over our planet, Sentinels in space. They monitor changes on land, at sea and in the air. Satellites allow us to see our planet in a new way. They present earth from above. Recently, NASA has compiled some of the trillions of digital data that satellites have sent back to Earth. The result is an all inspiring view, one no human had ever seen before without the confusion of clouds waken see the earth breathe with the seasons, the Northern Hemisphere breathes out with the arrival of autumn in the grip of winter, while at the same time the Southern Hemisphere inhales fresh life with the arrival of spring, the planet is like a living being pulsing with the life that ebbs and flows with the seasons. For the first time, we can not only understand but see our earth as an entity. Michael Robson fell in love in 1948 with a place he'd never been as soon and as often as he could. First on school holidays and later on breaks from work, Robson surrendered to the call of the heh birdies, making long journeys from the mainland by steamer and bus by small boat and on foot, venturing from the mountains of sky to the moors and see locks of Lewis and Harris and even farther across miles of ocean toe, a rocky speck of land where the last permanent settlement had been abandoned a century before. Such a storm of shot and shells were sent forth. Is no battlefield in America Ever witnessed? Federals were not taken by surprise for in a few seconds they're solid shot were tearing up the ground around us and their shells bursting in our very faces. As a chemical compound, nothing could be simpler than water. Two atoms of hydrogen joined toe one of oxygen. From a human point of view, however, simplicity fades. The water covers our world. More than 97% is salty. 2% is freshwater, locked in snow and ice. That leaves less than 1% for us. By the year 2025 1.8 billion people will live where water scarce.
