Whales beached after ingesting plastic, oceans soiled: a quarter of marine waste today comes from cans and plastic bottles. The drinks industry produces 470 billion single-use bottles each year, 25% of which come from Coca-Cola. Although the world's largest soft drink producer has set ambitious targets to prevent this environmental pollution, it has often failed to do so. In the 1950s, the company sold its drink exclusively in returnable glass bottles, which it washed and refilled. Two decades later, these were replaced by disposable bottles - a decision whose devastating effects still linger.

David Attenborough and scientist Johan Rockström examine Earth's biodiversity collapse and how this crisis can still be averted.

In Tacony Creek Park, home to one of Philadelphia's lesser-known watersheds, Julie Slavet and Malcolm Bundy reflect on their involvement with and love for the park, made bittersweet by the continuous and increasing amount of pollution that flows into its river. Combined wastewater and stormwater sewage outfalls have affected Philadelphia's rivers for years, but as one innovative program mitigates this for the Schuylkill and Delaware, Tacony gets left behind. Scientist Laura Toran educates the audience on green infrastructure and its potential positive impacts, while Slavet and Bundy discuss how they're still waiting—not without hope—for those impacts to reach their community.

Jellyfish blooms are making headlines around the world. This is due to the damage they cause to tourism, fishing and our health. How can these creatures, which are over 98% water and have no shell, skeleton or brain, expand so rapidly?  Although this is a normal stage in the life cycle of these gelatinous animals, we have to admit that blooms have become much more frequent and massive in recent decades. We're even witnessing jellyfish populations appearing in more and more regions where fish have been replaced by them, such as off the coast of Namibia, in the Black Sea, in the Sea of Japan and in certain areas of the Baltic Sea. What causes this? Why has the role of jellyfish in the ocean been underestimated, even though they outlived the dinosaurs? Are jellyfish on their way to dominating the oceans as they once did? What if they were to be the only ones left?

Oases are more than fairytale places in the desert sand. Amidst the stony heights of the Andes, the endless expanse of the Pacific, or the hectic concrete sausages of Mumbai, islands of life flourish. In breathtaking shots, the documentary explores the phenomenon of oases – and the magical places in the Saharan sand are of course included.
