In Florida, humans have caused more than 2000 manatee deaths since 1974. Collisions with boats and boat propellers cause roughly twenty-five percent of all manatee deaths. Another significant cause of the declining population is the disappearance of manatee habitats, resulting primarily from coastal development, water quality problems, and the change in water levels caused by Florida’s flood control systems. A constitutional amendment has been proposed that would protect natural systems and biological diversity. Which would be the MOST likely requirement of a constitutional amendment to protect the manatee population?
