It’s unfortunate but boats are killing manatees in Florida at a record-setting pace so far this year.

The Naples Daily News reported on Saturday that as of July 22, 2016 that the Florida Fish and Wildlife Conservation Commission has counted 71 manatees that have been hit and killed by boats. In 2009 97 manatees were killed by boats and it’s only the middle of the year.

The Save the Manatee Club say that cheaper gas prices, a better economy, a mild winter and a hot summer have all played a role in getting more boats in the water this year.

Boating professionals say that polluted Florida waterways have reduced the manatee habitat, making them more vulnerable to being killed by boats.
