Nearly 300 Sea Turtles Dead as Red Tide Plagues Southwest Florida

Hundreds of sea turtles have washed up dead along the southwest Florida coast as an ongoing red tide event persists in the waters.

The Florida Fish and Wildlife Conservation Commission has logged 287 sea turtle deaths since the virulent algal bloom started in October, the Associated Press reported.


That figure is twice the average number of turtle deaths in those waters each year, Allen Foley of the commission's Fish and Wildlife Research Institute told the AP on Thursday.

Foley explained that the turtles get sick and die when their food gets contaminated by toxic bloom.

The most vulnerable species affected include loggerhead and Kemp's ridley sea turtles, both of which are federally protected, the AP reported.

Researchers told the Fort Myers News-Press that the mortality event could impact the recovery of the protected species. Kelly Sloan, a sea turtle researcher at the Sanibel-Captiva Conservation Foundation, said her organization has picked up 91 sea turtles since the bloom started.

"Most of them have been mature adults, and only 1 in 1,000 make it to adulthood," Sloan told the paper. "It takes a loggerhead 25 to 30 years to mature, so that really does have a significant impact on their recovery."

The fate of the Kemp's ridley could be even worse. The species is considered the world's most endangered marine turtle.

The red tide, which is caused by the Karenia brevis organism, is a natural phenomenon but some have pointed fingers at climate change, as well as mining and agricultural practices that can cause excess nutrients to flush into the waters.

"Toxic algae blooms like this occur naturally, but they have grown in frequency and intensity in recent years. While the causes are subject to some debate, the likely culprits are a combination of elevated water temperatures from climate change, increased nutrient load from Big Sugar, phosphate mines and other sources, and some bad decisions by the Army Corps of Engineers," Greenpeace Oceans Campaign director John Hocevar said in a press release.

Besides sea turtles, Greenpeace said that the red tide has harmed other types of marine life as well as people in the region who have reported respiratory problems. Red tide blooms can cause human health concerns when they are ingested from eating contaminated seafood or inhaled when the toxins are aerosolized.

"Greenpeace supporters in Southwest Florida just contacted us about a devastating toxic algae bloom stretching across several counties. Fish, sea turtles, pelicans, sharks, and even manatees are washing up dead, and many people are reporting respiratory problems. Local businesses are struggling," Hocevar said.

Greenpeace is urging greater attention to this environmental and potential public health threat.

"More must be done for Southwest Florida, and with urgency. The health and well-being of people and the environment must be prioritized over corporate interests like Big Sugar in the region," Hocevar said.

A Record 589 Sea Turtles Killed By Florida's Toxic Red Tide

Florida's longest red tide in more than a decade has killed scores of the state's most iconic marine animals.

The current outbreak, which began in October 2017 off southwest Florida, has been tied to a record 589 sea turtle deaths and 213 manatee deaths, the Herald-Tribune reported, citing figures from the Florida Fish and Wildlife Conservation Commission.

Wildlife Under Siege at the World’s Oldest Lake

By Marlene Cimons

Lake Baikal is the world's oldest and deepest lake. It's at least 20 million years old, and roughly a mile deep at its lowest point. The Siberian lake contains holds more water than all the North American Great Lakes combined, what amounts to more than one-fifth of all the water found in lakes, swamps and rivers. It was formed by the shifting of tectonic plates, which created a valley that filled with water. That shift continues today at a rate of around 1 to 2 centimeters year, meaning the world's biggest lake is only getting bigger.

U.S. Oil and Gas Industry Is Drilling Us Towards Climate Disaster

By Kelly Trout

As the 116th Congress commences, in the wake of dire reports from climate scientists, the debate over U.S. climate policies has taken a welcome turn towards bold solutions. Spurred on by grassroots pressure from Indigenous communities, the youth-led Sunrise Movement and communities from coast to coast fighting fossil fuel infrastructure, Capitol Hill is alive once again with policy proposals that edge towards the scale required to address the crisis we're in.

2018 Was the Hottest Year Ever Recorded for Our Oceans

The year 2018 was the hottest year for the planet's oceans ever since record-keeping began in 1958, according to a worrisome new study from international scientists.

The findings, published Wednesday in the journal Advances in Atmospheric Sciences, noted that the five warmest years for our oceans were the last five years—2018, 2017, 2015, 2016 and 2014 (in order of decreasing ocean heat content).

Senate Shouldn’t Put Wheeler at the Wheel of the EPA

By Ana Unruh Cohen

As the longest government shut down in history drags on, and the experts protecting our air and water remain off the job, the Senate is barreling forward to put Andrew Wheeler at the wheel of the U.S. Environmental Protection Agency (EPA). He is unfit for this public trust.

In his seven-month tenure as the acting administrator at EPA, Wheeler's relentlessly pushed to advance the pro-polluter agenda launched by Scott Pruitt, the worst administrator in the agency's storied 48-year history. Wheeler may lack Pruitt's scandals, but he's no improvement.
