An alarming decline in insect populations could devastate all life on earth. What's causing it, and can anything be done to stop it? Insects are disappearing across the world. If we lost our pollinators, we would lose 80 to 90% of the plants on the planet. That is not an option. It's the ecosystems on this planet that keep humans alive. ... Scientists warn us that the insect apocalypse is entirely possible.

Beneath Yellowstone National Park, lies the biggest volcano on Earth. An eruption in the past was so big it plunged the earth into a volcanic winter that lasted years. A super-eruption would be more than millions of Hiroshima bombs going off all at once. It would be even worse than an asteroid impact: Entire cities lost beneath ash, people an ...d animals crushed alive, power networks destroyed, sun dimmed across the globe, harvests failed, widespread famine.
Could this nightmare really happen? We will use the latest scientific data to uncover the danger beneath us, as we see our planet like never before.

Black holes are the most enigmatic and exotic objects in the universe. They’re also the most powerful; with gravity so strong it can trap light. And they’re destructive, swallowing entire planets, even giant stars. Anything that falls into them vanishes... gone forever. Now, astrophysicists are realizing that black holes may be essential to h ...ow our universe evolved—their influence possibly leading to life on Earth and, ultimately, us. In this series, astrophysicist and author Janna Levin takes viewers on a journey to the frontiers of black hole science. Along the way, we meet leading astronomers and physicists on the verge of finding new answers to provocative questions about these shadowy monsters: Where do they come from? What’s inside? What happens if you fall into one? And what can they tell us about the nature of space, time, and gravity?
