Sea Turtle Population Rebounding But Many Threats Remain

A new study published in Science Advances has found that most global sea turtles populations are recovering after historical declines.

The results from the analysis suggest that conservation programs actually work, and why we must defend the Endangered Species Act (ESA) that protects vulnerable plants and animals, and is currently under attack by political and business interests.


It's not exactly clear why sea turtle populations are making a comeback, but as the New York Times reports, conservation efforts since the 1950s have safeguarded beaches, regulated fishing and established marine protected areas, leading to a boost in turtle numbers.

"Our findings highlight the importance of continued conservation and monitoring efforts that underpin this global conservation success story," Antonios Mazaris, an ecologist at the Aristotle University of Thessaloniki in Greece, and his team of international researchers wrote in the study.

All sea turtles found in U.S. waters are listed under the ESA. But the Center for Biological Diversity reported that since January, congressional Republicans have launched 50 legislative attacks against the environmental law or on a particular endangered species.

David Godfrey, a member of the International Union for Conservation of Nature's Marine Turtle Specialist Group and executive director of the Sea Turtle Conservancy, told Newsweek that lawmakers could decrease funding needed to protect vulnerable species or even delist a species from the ESA.

As Godfrey explained to Newsweek:

"You have an administration at the federal level now and members of Congress who would like to diminish the strength of the Endangered Species Act," he said. "There have been complaints for years that it's ineffective, it doesn't work, we're wasting money."

Spreading to the world that these policies are working might push back against those perceptions, but Godfrey hopes the good news won't convince people that all the needed work has been done. "It's something we should acknowledge and be trumpeting," he said. "But it doesn't take long for the trend in their population to start going the wrong way."

The researchers in the current paper note that sea turtles populations are not rising across the board, such as the declining number of leatherbacks in the Eastern and Western Pacific. Their findings reflect the International Union for Conservation of Nature's Red List, which lists six of the seven types of sea turtles species as vulnerable, endangered or critically endangered.

  • Research shows that 16 weeks of a vegan diet can boost the gut microbiome, helping with weight loss and overall health.
  • A healthy microbiome is a diverse microbiome. A plant-based diet is the best way to achieve this.
  • It isn't necessary to opt for a strictly vegan diet, but it's beneficial to limit meat intake.

New research shows that following a vegan diet for about 4 months can boost your gut microbiome. In turn, that can lead to improvements in body weight and blood sugar management.

Nearly 20 years have passed since the journalist Malcolm Gladwell popularized the term tipping point, in his best-selling book of the same name. The phrase denotes the moment that a certain idea, behavior, or practice catches on exponentially and gains widespread currency throughout a culture. Having transcended its roots in sociological theory, the tipping point is now part of our everyday vernacular. We use it in scientific contexts to describe, for instance, the climatological point of no return that we'll hit if we allow average global temperatures to rise more than 2 degrees Celsius above preindustrial levels. But we also use it to describe everything from resistance movements to the disenchantment of hockey fans when their team is on a losing streak.

On Aug. 18, Iceland held a funeral for the first glacier lost to climate change. The deceased party was Okjökull, a historic body of ice that covered 14.6 square miles (38 square kilometers) in the Icelandic Highlands at the turn of the 20th century. But its glory days are long gone. In 2014, having dwindled to less than 1/15 its former size, Okjökull lost its status as an official glacier.

Eco-anxiety is likely to affect more and more people as the climate destabilizes. Already, studies have found that 45 percent of children suffer lasting depression after surviving extreme weather and natural disasters. Some of that emotional turmoil must stem from confusion — why aren't adults doing more to stop climate change?
