Can planet Earth survive? Can we survive as a species? Changes in population growth could be a key factor to allowing us to prosper and live in harmony with nature once again.

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!

Today, planet Earth is in a new era, the Anthroprocene. Humankind has harnessed and exploited Earth’s resources, changing its surface, devastating populations of wild animals, cutting down trillions of trees and leaving very little of what was “wild.” The enormous loss of biodiversity is not sustainable. How can we create a future in which both people and nature can thrive?

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.

As the last of the winter snow melts, fresh mountain meadows are once again revealed, and the animals take their chance to feed. Glacial meltwater flows into torrents, forming streams and rivers. Brightened by rich sediment, they transport vast quantities of gravel downstream, carving new landscapes in their wake.

As spring arrives in the mountains, the first flowers appear with the sun, and the chamois descend the slopes in search of the first few blades of fresh grass. The ravens are feeding a brood of noisy youngsters, and, high up on an unapproachable crag, Biker the eagle sits on her nest.

Under the ice, the water of the Alpine lakes never freezes, and fish can survive the harshness of winter. In February, eels and other fish species are spawning, depositing the eggs that will give life to their next generations. Along fast-flowing mountain streams, ice doesn’t form, and the dipper dives in search of invertebrates, crustaceans, and other tiny prey.

In winter, Europe’s greatest mountain range, the Alps, lies blanketed by snow and ice. For the majestic golden eagles, who make these remote and impressive peaks their home, these are hard times, and food is scarce. But one eagle is lucky: An avalanche results in an unexpected meal.

Just how smart are dolphins? Can they tell their own reflection apart from another dolphin? Here we see examples of "self-directed" behaviors that answer this question.

In New Orleans, a city that has been hit very hard by the coronavirus, musician Anna Roznowska and pedicab driver Sarah Grant have teamed up for a mobile performance project. Together, they drive through the city’s empty streets with Anna playing the violin, lifting the spirits of people stuck at home. "People are very hungry for music," said Roznowska.

We all know that crows are smarter than the average bird, but will 007 be able to solve the complex puzzle and retrieve his reward?

Off the coast of California, an island of floating kelp provides refuge for fish in the open waters. The many small fish then attract larger species, including the ocean sunfish that seek relief from their parasites, and the predatory blue shark.

The harbor seals gather in a sheltered cove to give birth. But even hidden from predators, there is no guarantee of survival, and we witness the tragic death of one newborn that gets trapped in its amniotic sac. Within a few hours, the pups that survive the birth are already into the waves, getting to know their new watery world.

Life can be hard in the Californian desert, but many plants and animals are adapted to survive the hot, dry conditions. Jackrabbits, owls, hummingbirds, and the green stick tree all thrive in this harsh climate as they wait for the rare blessing of rain.

Decades later, the events of the nineteen eighty-eight Winter Olympics seem harder and harder to believe, even to the men at the heart of the original Jamaican Bobsled team. But it really did happen, and the proof is in the strong sporting and commercial legacy they leave for the next generations.
