Bacteria, viruses, but also fungi, algae, pollen, and even insects: micro-organisms thrive and circulate constantly in our sky. How can so many living beings find their way into the air and circulate? How do they survive? And what influence do they have on our lives and the living world? Biodiversity, health, climate: it is only recently that scientists have begun to understand how this discreet aerial "plankton" affects our lives and our ecosystem. But despite their many virtues, some of these micro-organisms are now threatened by human activities. With the help of experts and 3D models, this scientific investigation plunges us into the heart of a still mysterious world, and reveals the diversity and fragility of the air we breathe.

Last May record temperatures provoked a GLOF or glacial lake outburst flood in northern Pakistan, sweeping away bridges and villages in the valley below the Shisper glacier. Higher up the mountains, a semi-nomadic people called the Wakhi were leading their yaks to summer pastures 15,500 feet above in the mountains. Their traditional lifestyle has also been heavily impacted by climate change. From the K2 and the Himalayas, we profile the scientists,mountain climbers, and the villagers on this global warming frontline.

Offshore wind farms are a major player in the move away from fossil fuels, especially in the North Sea, and they are increasing in number. But their impact on the environment is not yet clear: We take a look at ongoing research in Europe that is measuring the impact of wind turbines and their harm, or benefit, to biodiversity in our seas.

Among the many parts of the world in which Unilever companies operate, West Africa has a special place. The Africa of popular imagination is a land of jungles, swamps and mud huts; but side by side with the traditional, a new Africa is growing and the film "African Awakening” is an expression of this, of the attitudes of those African men and women who are today the driving force of West African progress. “African Awakening”, a colour film which runs for 38 minutes, is one of a series of Unilever films dealing with different aspects of African life.

An epic journey along Africa's Great Green Wall — an ambitious vision to grow a wall of trees stretching across the entire continent to fight against increasing drought, desertification and climate change.

In 2001, satellite imagery captured a mysterious “thermal anomaly” on an unexplored volcano at the ends of the Earth. What lies inside could provide new clues to help predict volcanic eruptions around the globe. But the island is so remote with conditions that are so extreme. No one has ever been able to reach the top to investigate what lies inside.. until now.
