Scientists are racing to create a cure for COVID-19, but the toll on sharks might be irreparable. Conservationists estimate that half a million of the predators may be killed to supply the world with a coronavirus vaccine when one is developed.

Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.

There are trillions of microplastics in the ocean — they bob on the surface, float through the water column, and accumulate in clusters on the seafloor. With plastic being so ubiquitous, it's inevitable that marine organisms, such as sharks, will ingest them.

Here at The Revelator, we love a good shark story.

The problem is, there aren't all that many good shark stories. According to recent research, sharks and their relatives represent one of the world's most imperiled groups of species. Of the more than 1,250 known species of sharks, skates, rays and chimeras — collectively known as chondrichthyan fishes — at least a quarter are threatened with extinction.

Sharks elicit outsized fear, even though the risk of a shark bite is infinitesimally small. As a marine biologist and director of the Florida Program for Shark Research, I oversee the International Shark Attack File – a global record of reported shark bites that has been maintained continuously since 1958.

Every day, sharks suffer from different threats. Up to 100 million sharks disappear every year, due to destructive fishing by humans and the impact of climate breakdown. One-third of the world's known shark species have been listed as "threatened" species by the International Union for Conservation of Nature.

A landmark study by Global FinPrint reveals sharks are absent on many of the world's coral reefs, indicating they are functionally extinct — too rare to fulfill their normal role in the ecosystem.

When Jasmin Graham describes her research on smalltooth sawfish, a critically endangered ray with a unique "saw" at the front of its face, she explains how "nothing else looks like this in the ocean; those species evolved to do something no other shark or ray can do." It resonates, and people understand why diversity matters in sharks, she said. She expanded on this same concept to emphasize how diversity also matters in finding solutions to the challenges that threaten elasmobranchs and in those scientists doing that work.
