The manatee is an aquatic mammal—three species of which are found in both North and South America along with western Africa. Often called "sea cow," a manatee can weigh up to 1,500 pounds and grow to 10 feet long. The manatee has no known predators other than humans but—as you can imagine - that's more than enough. Habitat destruction, water pollution, and hunting have put all three manatee species in danger of extinction.
Perhaps the most specific, direct threat to this seal-like herbivore is the omnipresent powerboat. When you combine the speed of such vessels with the fact that manatees are slow, near-surface swimmers, well...let's put it this way: In 1990 alone, 12% of the United States' manatee population (218 manatees in all) were killed in boating accidents and things haven't exactly improved since then.
What We Can Do to Save the Manatees:
Working to make sure that boat speed zones are enforced is a solid first step. As is the case with many endangered species, some groups offer options like "adopting" a manatee or working to create new legislation. Those who live where manatees are found can become part of a sighting network.
Perhaps the most important gesture - not just for the manatee but for us all — would be to recognize that our culture has put us out of balance with nature. This is what the amazing Kogi people call "Koyaanisqatsi." A human culture more in tune with its natural surroundings would instinctively and reflexively choose manatees over speed boats.
