This documentary focuses on life in ancient oceans during each prehistoric period, providing a fine focus on evolutionary proceedings. Nothing, not the carnivorous dinosaurs of the past, nor the imagined sea serpents and monsters of maritime history, nor the great white shark, salt water crocodile, killer whale and leopard seal of today can compare to the horrifying hunters of the prehistoric oceans. You will feel a lot more comfortable about going out for a swim or an afternoon boat ride knowing that such behemoths are extinct today!
Because it is there is the reason so many men and women have risked death to climb Mount Everest, the tallest mountain on earth. NOVA follows a scientific investigation of high-altitude physiology in Everest: The Death Zone, which examines the biological and psychological changes experienced by a group of climbers during their ascent. Jodie Foster’s narration accompanies the team as the NOVA photographers capture the stark, alien beauty of the mountain; the drama reaches a crescendo on the descent as it becomes unclear whether or not an ill climber will make it.
If it were up to the sun, we would have no energy problem. Every half hour on the Earth’s surface, there is more than enough light to provide energy needs for the whole world in a year. We don’t have an energy problem, we have a conversion problem. If we are able to harvest sunlight in smart way, then we can prevent a global energy crisis. That sounds nice but that does not mean it will succeed, at least that is what many different bodies want us to believe. It’s too expensive, takes too much space, too much material, it costs more energy than it brings, and it is still not efficient enough. While all these doubts play a role for solar energy in the distant future, it is still a marginal player in the global energy game.
Imagine if one minute from now, every single person on Earth disappeared. All 6.6 billion of us. What would happen to the world without humans? How long would it be before our nuclear power plants erupted, skyscrapers crumbled and satellites dropped from the sky? What would become of the household pets and farm animals? And could an ecosystem plagued with years of pollution ever recover?
With exclusive footage, NOVA captures the unfolding human drama and offers a clear headed investigation of what triggered the earthquake, tsunami, and subsequent nuclear crisis. In its worst crisis since World War II, Japan faces disaster on an epic scale. A death toll likely in the tens of thousands, massive destruction of homes and businesses, shortages of water and power, and the specter of nuclear meltdown.
