Seafood is a substantial part of the daily diet of over three billion people and oceans absorbs almost a third of all the greenhouse gases we emits. Buy the ocean it is not what it once was. Scenes of extraordinary ocean abundance now only exist in far-off places or in tales from the past. We urgently need to mend our relationship with our oceans and allow them to thrive once again.
Prince William, David Attenborough and Shakira find out about inspiring people and projects across the world that can help us stop damaging the oceans and enable their revival.

Will explore the strategy, deception and feats of engineering plants use to thrive in the changing weather of different seasons. In the face of conditions ranging from ice and snow to raging fires, survival is often a question of perfect timing - particularly when contending with intense competition and surprising predators.
In this episode, David Attenborough travels to Finland to show one of the most extreme examples of seasonal plant life in the Arctic Circle. He also travels to California to see how climate change is affecting giant sequoias. These ancient trees like all other seasonal plants depend on the predictability of the seasons and our current changing climate threatens their survival.

In the third episode, during cleanup at the plant, insiders claim that cost-cutting measures and intimidation tactics create a danger war force than the accident itself.
Several state and federal government agencies mounted investigations into the crisis, the most prominent of which was the President's Commission on the Accident at Three Mile Island, headed by chairman John G. Kemeny. The investigation strongly criticized Babcock & Wilcox, Met Ed, Graphics processing unit, and the Nuclear Regulatory Commission for lapses in quality assurance and maintenance, inadequate operator training, lack of communication of important safety information, poor management, and complacency.
Kemeny said that the procedures and that the control room were greatly inadequate for managing an accident.

Chris turns to longevity doctor Peter Attia to find out how changing his eating habits can help his quest for longevity. Ironically, the answer is to eat no food at all for four long days. If he can bear the hunger, fasting will unlock his body’s own anti-aging powers and give Chris the edge he needs when he tries to hunt for his next meal … by spearfishing off the Great Barrier Reef.

Over the past year, Chris Hemsworth have been exploring the science of living longer, doing everything he can to hold back time. But whatever he does, sooner or later, aging and death will win. Now Chris is facing his most extreme and emotional challenge: three days in a retirement village while wearing an aging suit that turns the simplest activity into a Herculean task. He'll be carrying an extra 30 pounds around and shoes that will make him unbalanced, apart from glasses to see improperly and acoustic earmuffs. Later on, Chris is going to do a death-bed meditation. He’s testing the theory that the best way to combat aging and fear of mortality might not be to fight it but accept it,
