The Florida manatee, a subspecies of the West Indian manatee, is a large ocean mammal found in Florida's rivers and coastal areas. Unfortunately, the state's population of manatees has dwindled significantly over the years. Although the manatee has no natural predators, humans have contributed to many manatee deaths, mainly through boat collisions. The loss of warm-water habitats has also hastened the manatee's decline. Aerial surveys performed in the early 1990s found an estimated 1,267 manatees in Florida. Because of conservation efforts by several organizations, however, the number of manatees has rebounded recently. The creation of manatee protection zones—areas that boaters must avoid or drive through more slowly—has been particularly effective. As a result of these efforts, more than 6,000 manatees are found in Florida today. What is the main idea of the passage?

if the boats are allowed at all manatee protection zones, they are required to go at slower speeds.

thanks to conversations efforts, Florida manatee populations have increased

This is not a question i really do not get what you're are saying
