Many of the world’s glaciers are melting away at an alarming rate due to the effects of global warming. There is little left to show of the once great alpine glacier, The Pasterze, that used to stretch for five kilometres on the slopes of the Grossglockner, Austria’s highest peak. But life goes in the Alps: An eagle chick is hatching from its egg. Small and vulnerable, it will depend entirely on its parents as it begins to grow and investigate its new environment.

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.

A film about the global sustainability work of The Prince's Charities, founded by HRH The Prince of Wales.

The Prince of Wales' Accounting for Sustainablity project is offering two concrete intervention options for companies and their policies, which lead not only to tangible profits, but also help to reduce the supply chains.

The Prince of Wales and The Duke of Cambridge talk about the unprecedented levels of killing of endangered species like elephants, which are killed at a rate of 100 per day. They also highlight the grave threat the illegal wildlife trade poses to the economic and political stability in many areas around the world and make a plea for the public to support those organisations that are working to put an end to the trade.

In this second half, The Prince of Wales and The Duke of Cambridge follow up by sharing some of the things that are being done to combat the wildlife trade and encouraging the listener to take action. They end by speaking the phrase "Let's unite for wildlife" in Vietnamese, Mandarin, Swahili, Spanish, Arabic and English.

Natalie Fee talks with candor and sensitivity about some usually taboo aspects of daily life and how they affect plastic pollution. She then shows a film clip by artist Chris Jordan that is very difficult to watch, as it shows how litter is killing seabirds.

Natalie Fee talks about impact the clip (at the end of the previous segment) had on her life and how she started out on her journey. One stop on that journey was a music video.

Natalie provides some facts and figures about how much garbage is getting flushed down the toilet in the UK, and goes on to tell us about a successful campaign she spearheaded, aimed at manufacturers of cotton swabs.

Natalie provides some tips for wasting less plastic and leaves us with a slogan to help us rethink our flushing habits. She involves the audience to bring the message home.

Natalie Fee concludes her Ted Talk with a few suggestions for what we can do to reduce how much single-use plastic we are sending into the earth's waterways.

A look at the communications of Humpback Whales and other baleen whales, which includes how they sing, why they sing, and why we might consider their vocalizations actual songs.

Dolphins are one of the smartest animal species on Earth. In fact, their encephalization quotient (their brain size compared to the average for their body size) is second only to humans. But exactly how smart are they? This video shares some incredible facts about dolphins.

We all know that whales are endangered due to hunting and pollution, but do you know how important they are for the ocean and the environment? This video shows how essential a healthy population of whales is to the ocean ecosystem. Creative Commons Attribution license (reuse allowed). Video was not modified.

In recent years, we've seen an increase in the intensity of tropical storms and hurricanes due to global warming. But how and why do hurricanes form? Sigrid provides a basic explanation of this phenomenon.

We continue to explore the phenomenon of hurricanes. Why are they so dangerous? And do they serve any purpose?

This Yabla news broadcast features stories about two different kinds of animals, one enormous and one tiny. Sometimes we can predict how animals will behave, and sometimes not.
