Red coral is the literal foundation of many Mediterranean ecosystems, and provides critical habitat for fish and other marine life. Harvesting by humans, pollution, ocean acidification, and warming waters all threaten the coral, which is now endangered. Efforts are underway to help preserve it, with some jewelry companies refusing to sell coral products, and the Catalan government will enact a decade-long moratorium on fishing starting in 2018.

A determined young elephant breaks traffic laws to get to its destination. Video captured outside of an Indian wildlife sanctuary shows the pachyderm encountering two railway barriers that were lowered for an oncoming train. The elephant gently lifts one of the barriers and slips underneath. It then steps over the second barrier. The scene is a fascinating observation of the elephant’s problem-solving abilities, and its blatant disregard for traffic safety measures.
