A new force threatens our perfect planet. In the past, five mass extinction events were caused by cataclysmic volcanic eruptions. It was not the lava or ash that wiped out life, but an invisible gas released by volcanoes: carbon dioxide. Almost every part of modern life depends on energy created by burning fossil fuels, and this produces CO2 in huge amounts. Humans are changing our planet so rapidly, it’s affecting earth’s life support systems: our weather, our oceans and the living world. The greatest change to be made is in how we create energy, and the planet is brimming with natural power that can help us do just that. It’s these forces of nature - the wind, the sun, waves and geothermal energy - that hold the key to our future.
Through compelling animal-led stories and expert interviews, we discover how CO2 is destabilising our planet. We meet rescued orphaned elephants in Kenya, victims of ever worsening droughts, and join ocean patrols off the coast of Gabon fighting to save endangered sharks. In the Amazon, we witness wildlife teams saving animals in the shrinking forests, and in San Diego we enter a cryogenic zoo preserving the DNA of endangered species before they become extinct.

After ending 120 years of civil war and reunifying Japan under his banner, Toyotomi Hideyoshi, the supreme ruler of Japan, lays dead. In a desperate attempt to protect his dynasty, just before his death, Hideyoshi created a council of five powerful warlords. They are to govern Japan until his young son comes of age. But the power hungry Tokugawa Ieasyu declares war on those who oppose him.

After more than a century of civil war, Toyotomi Hideyoshi has united Japan. His rivals have either sworn their allegiance, or they have been destroyed. Despite this fledgling peace, Hideyoshi now dreams of a bold and outlandish plan to make himself the most powerful man in Asia. He plans to expand his reign to China. Logistical challenges and fierce operation in Korea prove to be costly.

After unifying much of Japan, fearsome samurai Oda Nobunaga is dead. His loyal supporter Toyotomi Hideyoshi has launched a coup and seized power for himself. Enraged, powerful General Katsuie has launched his own bid to control the nation.
After defeating Katsuie, Hideyoshi finally ascends to power as the de facto ruler of Japan. Still, Date Masamune, a young daimyo in the north, ignores his missives.

Fueled by a ruthless and maniacal ambition to conquer Central Japan, Nobunaga has destroyed many enemies who have underestimated him. His vicious military campaigns to weaken the powerful Buddhist institutions have turned large swathes of the population against him. As Nobunaga's cruelty intensifies, some generals begin to question his command, leading to a betrayal that alters the political landscape forever.

Ten years after waging a bloody campaign to gain control over his own province, powerful samurai warlord Oda Nobunaga has seized much of Central Japan, including the nation’s capital, Kyoto. Now, driven by a towering ambition, he dreams of crushing the powerful clans who still oppose his rule. And for the first time in over a century, uniting all of Japan under one banner. But Nobunaga’s legendary brutality has caused widespread anger. Across the nation, powerful enemies now plot his demise.
