The San Francisco Earthquake is a thorough examination of the April 18, 1906, earthquake that is considered one of the first environmental disasters of the modern age. Striking California's Bay Area, the quake and its resulting fires destroyed a rapidly growing, prosperous city and left more than 500 people dead, thousands homeless, and $500 million worth of property damage.

In 2008, Professor Lee Berger--with the help of his curious 9-year-old son--discovered two remarkably well preserved, two-million-year-old fossils of an adult female and young male, known as Australopithecus sediba; a previously unknown species of ape-like creatures that may have been a direct ancestor of modern humans. This discovery of has been hailed as one of the most important archaeological discoveries in history. The fossils reveal what may be one of humankind's oldest ancestors.

After more than a century of peaceful dormancy, the volcano Nevado del Ruiz in Columbia, South America, erupted. Blistering clouds of searing volcanic gases and ash flash-melted huge amounts of snow, launching a towering wall of hot mud toward the village of Armero. People ran - but they couldn't outrun the onslaught, and 23,000 perished.

They have a touch so feather-light, it can barely be felt on human skin. The vividly gold and black colored golden orb weaver spider is the largest web-making spider on the planet. These elegant and efficient arachnids can weave impressive webs up to three feet wide in less than an hour. And these spiders' silk-spinning abilities could have far-reaching implications for science and medicine.

Joining the ranks of modern myth busters, Dr. Sharon Moalem turns our current understanding of illness on its head and challenges us to fundamentally change the way we think about our bodies, our health, and our relationship to just about every other living thing on earth. Through a fresh and engaging examination of our evolutionary history, Dr. Moalem reveals how many of the conditions that are diseases today actually gave our ancestors a leg up in the survival sweepstakes. But Survival of the Sickest doesn't stop there.

The world's seeds are in crisis.

Of 12,000 plant species used for human food, only about 150 are being grown for sale, only eight grains are traded throughout the world, and half of our calories come from just three: rice, wheat, and maize.

This means that our food diversity is diminishing at a shocking rate. More than on in five plants on earth are threatened with extinction. Our lives depend on all kinds of seeds, but they are facing many threats: war-torn countries, damaged habitats, and climate change, to name a few.
