Authorities say nutrient spills, especially too much nitrogen and phosphorus, can completely kill seagrass or form flowers that block sunlight.
“Most of the former 80,000 acres of seagrass in the Indian River Lagoon was lost by a series of harmful blue-green algae caused by decades of human nutrient pollution from wastewater and an unabated spill to this day. Former Governor of Florida Save manateesSaid in the editorial Release According to Tampa Bay Times.
Meanwhile, the Biodiversity Center (CBD) March study Over 55% of the manatees tested contained trace amounts of pesticides.

According to Graham, the U.S. Fish and Wildlife Service (FWS) “dropped the ball” in 2019. changed Conservation status of manatees from endangered to endangered.
“They are endangered because of the opposition of scientists and thousands of Americans who listened to anti-manatee groups and realized that the future of manatees is unsafe but could actually be worse. We removed manatees from the species list prematurely, “he said.
“We need to acknowledge the mistake and relist the manatees as endangered,” the FWS said.
