Some two million people flocked to the Greek island of Santorini last year. There were days when up to 18,000 visitors on cruise ships were seen disembarking at the island's port. That's a lot, especially considering that only about 15,000 people actually live on the island. Santorini is struggling to cope — and the very ecology of the island is at risk.

Climate change means that in many parts of the world, droughts are getting longer, more intense and more frequent. Alex Jones, director of the climate and environment division at the United Nations Food and Agriculture Organization, explains what that means for farmers around the world.

Soaring temperatures sparking wildfires that claim lives and damage crops are becoming a pattern. Last summer, vineyards on the US West Coast were hit. But some winemakers are making the most of the new, smoky flavor.

Much of the world is sweltering through a heat wave, and Germany is no exception. That's bad news for farmers in Brandenburg, who are still getting over heavy rains last year. Now, they're taking drastic action to save their crops from extreme weather.

Hundreds of years ago, the American eel was a common sight on the Ottawa River in Canada. But today, the endangered species is at just 1 percent of its former strength, due largely to the many dams on the river. And the Ottawa River is especially important for the American eel — it's where they go to mature before making the epic journey back to their spawning grounds in the North Atlantic.

Human's least-popular roommates — cockroaches — are hated in New York, and yet they are unavoidable. There are more roaches than people in New York, and they would likely survive a nuclear strike. Mark Stoeckle of the Rockefeller University in New York has researched the insects intensively — and even has some big news about cockroaches in New York!

People in Cambodia have developed a taste for tarantulas, starting during the brutal rule of the Khmer Rouge in the 1970s when people were starving and ate the crawling creatures to survive. To this day, people continue hunting down tarantulas, and sell them fried at market stalls. But habitat loss and hunting are driving them to the brink.

Drought is making life is tough for communities in the Coquimbo region of northern Chile, with climate change turning the area into a government-declared disaster zone. But an ingenious invention is helping farmers adapt to these changing conditions.

Wouldn't it be great if you could help the planet simply by kicking back and enjoying a nice cold beer? A brewery in Austria has figured out a way to help prevent food waste while producing a unique beer.

The greater horseshoe bat — one of the United Kingdom's largest and rarest bat species — is under threat from pesticides, habitat loss and roads. But help is at hand from a surprising source.
