Potato heritage

"In remote farms in the Andes Mountains, elevated thousands of feet above sea level, climate change is threatening a crop that is part of the region's identity: the potato. Farmers here say warmer temperatures are opening the door to the disease that caused the Irish potato famine. And unusual cold snaps during the growing season are also causing problems. The disease could be particularly devastating to Peru, because in these villages the potato is more than just a food — it's a culture." (Thanks D.)
