Number of sharks, rays have fallen more than 70 percent between 1970-2018 While climate change and pollution also imperil shark survival, increased fishing pressure is the greatest threat for every oceanic shark species.

Shark populations dropped 71% since 1970, study says Sometimes sharks are intentionally caught by fishing fleets, but more often they are reeled in incidentally as “ bycatch," in the course of fishing.

When marine biologist Stuart Sandin talks about sharks, it sounds like hes describing Jedis of the ocean. They are terrific predators, fast swimmers and they have amazing senses they can detect any disturbance in the ocean from great distance, such as smells or tiny changes in water currents. Their ability to quickly sense anything outside the norm in their environment helps them find prey in the vastness of the open ocean. But it also makes them especially vulnerable in the face of increase...

Globally, the abundance of oceanic sharks and rays dropped more than 70% between 1970 and 2018, according to a study published Wednesday in the journal Nature. And 24 of the 31 species of sharks and rays are threatened with extinction, while three species — oceanic whitetip sharks, scalloped hammerhead sharks and great hammerhead sharks — are considered critically endangered. Alarming decline in sharks. Overfishing has wiped out over 70% of some shark and ray populations in the past 50 yea...

  WASHINGTON -- When marine biologist Stuart Sandin talks about sharks, it sounds like hes describing Jedis of the ocean. "They are terrific predators, fast swimmers and they have amazing senses -- they can detect any disturbance in the ocean from great distance," such as smells or tiny changes in water currents.

And 24 of the 31 species of sharks and rays are threatened with extinction, while three species — oceanic whitetip sharks, scalloped hammerhead sharks and great hammerhead sharks — are considered critically endangered. “The last 50 years have been pretty devastating for global shark populations,” said Nathan Pacoureau, a biologist at Simon Fraser University in Canada and a co-author of the study. Sometimes sharks are intentionally caught by fishing fleets, but more often they are reeled...

What We’ve Lost: The Species Declared Extinct in 2020 Dozens of frogs, fish, orchids and other species — many unseen for decades — may no longer exist due to humanity’s destructive effects on the planet.

NationofChange What we’ve lost: The species declared extinct in 2020 The causes of these extinctions range from diseases to invasive species to habitat loss, but most boil down to human behavior. A few months ago a group of scientists warned about the rise of “extinction denial,” an effort much like climate denial to mischaracterize the extinction crisis and suggest that human activity isn’t really having a damaging effect on ecosystems and the whole planet.
