The eagle chick is growing fast and the need for food is constant. The eagles' perfect prey is the marmot, or “groundhog,” whose large fat reserves make it a tasty and nourishing meal. But these cute little mammals are watchful and wary, and have no intention of being on the eagles’ menu today!

In a nearby nest, another pair of eagles have managed to raise two young. But with survival at stake, the younger chick must fend off a vicious assault from its older sibling. Eagle-owls are also nesting on the mountainside. Ducks, hares, rats, hedgehogs, and even ravens make up the diet of these fierce nighttime hunters.

Things are calmer now in the Alps than two and a half million years ago, when the collision of two great continental plates forced them skywards. But even the splendid summer flowers, which bloom briefly in the high pastures, must be able to withstand a sudden outbreak of winter, cold mountain winds and a flurry of snow.

In late summer, the ibex are feeding in the high pastures, preparing for the winter ahead. The young males jostle and clash horns, testing their strength in a series of energetic show fights. As night falls, we catch glimpses of the powerful red deer, and Biker the eagle takes flight in an effort to coax her chick into the air.

Biker’s chick is strong enough, but lacks the courage to fly the nest. She must use food to tempt it into flight. The nest will then be empty, and other species can make use of its strength and secure position to raise their broods.

Eagle expert Andreas Mayrhofer climbs down to the empty eagle nest, where he will collect evidence of the eagles’ diet and habits. Autumn has arrived, spreading its mellow colors across the Alps. But this is no time to relax, and the eagles’ prey must be ever watchful. An escaped rabbit catches the eye of a hungry eagle.

A century ago, the golden eagle was a rare sight in the Alps and was on the verge of extinction. Nowadays, this bird of prey is better understood and protected and there are some one hundred and fifty birds just in the Karwendal and Northern Tyrol. Our young eagle makes his first kill, and soon his life will change as he must seek out his own hunting territory, alone in this mountain paradise.

Sting talks about the protection of the rainforest and the Rainforest Project of the Prince of Wales.

The Prince of Wales has set up a rainforest project in order to protect the remaining rainforests on this earth. He talks about the seriousness of climate change and how it will affect our lives and the lives of our children and grandchildren. He appeals to us to support him and his project.

Prince Charles launches a campaign to save the rainforests in an online video broadcast, featuring Hollywood stars Robin Williams, Daniel Craig and Harrison Ford, as well as Princes Harry and William.

The East Coast of the United States of America stretches from the tropical blue seas and white sand of Florida’s Sunshine State to the Canadian border in the North. We begin our journey in the warm and relaxed islands of the Florida Keys, where modern-day treasure hunters are still at work, hunting for sunken Spanish gold.

When the Fisher family of treasure seekers finally struck it rich, the local authorities tried to claim the bounty for themselves, and the case went to the Supreme Court. We learn how the “Florida Keys” got their name, and how these small outlying islands are linked to the mainland.

The town of Marathon in the Florida Keys is home to a unique hospital dedicated solely to caring for sea turtles. Marine biologist Bette Zirkelbach tells us about the dangers that sea turtles face in the wild. A lifesaving operation takes place, and a turtle is treated for a mysterious viral infection.

The only coral barrier reef in the United States surrounds the Florida Keys archipelago, and has been badly damaged by environmental pressures including ocean warming. The Coral Restoration Foundation is dedicated to its salvation, and in underwater nurseries, new coral is being grown to replenish the reef.

We head northward into the great swampy wilderness of the Florida Everglades. Airboat Captain Jesse Kennon knows his way around these marshes and where to find their most well-known and well-feared inhabitant: the alligator!
