The vibrant Sanibel and Captiva islands are ecological marvels compared to Florida's many overbuilt barrier islands. Development began with the construction of the Sanibel Island Lighthouse in 1884, when only the lighthouse keeper and assistant and their families lived on the island. Noted conservationist Jay N. "Ding" Darling led the charge in preserving the islands' wildlife and natural beauty from the greed of real estate speculators and land developers in the 1930s. Former presidents like Harry Truman and cabinet-level executives worked alongside Sanibel and Captiva residents, setting up preserves and wildlife refuges to guard the integrity of the islands' unique natural blessings, abundant wildlife and aquatic stores. Charles LeBuff and Betty Anholt review the evolution of the islands' conservation ethic and how it perseveres even today.
