| | Off Mexico’s Baja California Sur coast, Isla Espiritu Santo is a haven for colorful reef fish, sea turtles and other marine life. When a proposed casino threatened the island in the 1990s, local philanthropists worked with
donors from The Nature Conservancy and World Wildlife Fund to help protect this natural treasure. It is now one of Mexico's national parks.
