Starting on the most pristine reef on Earth, home to more predators than prey, Sanjayan draws on his own ocean experiences to reveal a vibrant community of scientists, engineers and fishermen who are providing solutions that can help restore the oceans in astonishing ways. He is aware of the vast scale of the threat to our oceans, but standing in the water playing midwife to a large lemon shark is just one of the moments that give him hope that we can turn around our influence on the most important habitat on Earth.
More than 2,000 years ago, the thriving city of Petra rose up in the bone-dry desert of what is now Jordan. An oasis of culture and abundance, the city was built by wealthy merchants who carved spectacular temple-tombs into its cliffs, raised a monumental Great Temple and devised an ingenious system that channeled water to vineyards, bathhouses, fountains and pools. But following a catastrophic earthquake and a slump in its desert trade routes, Petra’s unique culture faded and was lost to most of the world for nearly 1,000 years.

A brief history of the Italian Risorgimento provides the context for the great flight from the mezzogiorno region. By the late 19th century, Italians begin to put down roots and “Little Italys” spring up in urban areas throughout the U.S. But the first generation, holding onto language and culture, is branded “outsiders” and mistrusted by non-Italians. In New Orleans, this mistrust explodes into violence and 11 Italian Americans are murdered by an armed mob.
A team of genealogists uncovers fascinating family histories at The Historical Society of Pennsylvania.
