In the Taurus Mountains Simon stays with descendants of the original Turks, nomads known as Yoruks, whose lifestyle is under threat from the modern world and an increasingly religious government. They're not the only minority at odds with the authorities in Turkey; Simon sees first-hand the devastating effects of fighting in the country's Kurdish region. In an area where the government has detained foreign journalists, Simon gathers unique footage in the aftermath of a crackdown on Kurdish militants - the wholesale destruction of the historic centre of one of Turkey's oldest cities. Away from the conflict in the south, Simon heads towards the Black Sea coast. He meets a wildlife conservationist protecting Turkey's population of brown bears, and villagers who still communicate over long distances using an ancient bird language. In the country's capital he meets a victim of President Erdogan's authoritarian purge of people accused of complicity in the failed coup against him. Finally Simon's journey comes full circle when he returns to Istanbul - home to the new craze of 'Ottomania', a celebration of the vast empire that preceded modern Turkey. Simon visits the set of one of the world's most popular TV dramas - even getting a speaking role - based in the court of an Ottoman sultan
To survive Mars, our species will need to evolve how we eat, drink, and build our homes. Will we need our genes to evolve as well? Sometime in the future humans will leave Earth to colonize Mars, and in doing so will begin to adapt to life on another planet in surprising ways. Evolutionary biologist Dr. Scott Solomon foresees a series of changes to our species from the size of our hearts and heads to the pigments in our skin.
Even as the science grew more certain, the oil industry continued to block action to tackle climate change in the new millennium. In a revelatory interview, Christine Todd Whitman, George W. Bush's former environment chief, tells the story of how the industry successfully lobbied President Bush to reverse course on his campaign promise to regulate carbon emissions. Tensions grew between two of the world's biggest oil companies, ExxonMobil and BP, after the latter publicly called for action to tackle climate change. The election of Barack Obama provided hope for supporters of climate action, but the billionaire Koch brothers made an effort to block the new president's attempts to pass climate change legislation, and climate denialism became the mainstream position of the Republican Party. A lawyer who worked for Koch brothers through this period speaks on camera for the first time.
Principles of generosity and prosperity inform the selection of the last two crew members: Christopher Sembroski, a former member of the U.S. Air Force who served in Iraq and now works as a Lockheed Martin engineer, and Sian Proctor, a professor of geosciences and two-time NASA astronaut candidate. Excitement for the flight ramps up, but anxiety lingers.
Nathan decides to practice his own assertiveness in relationships by challenging Angela over their son's religious upbringing. Angela, a fervent Christian, refuses to allow Adam to be raised in Nathan's Jewish faith, so Nathan secretly brings his son to lessons with a tutor in Judaism under the pretense of swimming lessons. Seeking solace outside the house, Nathan opens his replica Alligator Lounge to the public under the name Nate's Lizard Lounge. The co-parents argue over a comedy skit featuring six-year-old Adam as 'Dr. Fart' and a joke about eating faeces, which Angela claims is a Satanic practice. Nathan rehearses the confrontations with a fake Angela, and in one scenario, she harshly criticizes Nathan's emotional detachment and questions the ethics of the entire production. However, in their real final confrontation, Angela simply decides to quit the rehearsal. Nathan continues to raise Adam, now as a single parent.
