About
Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.
Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...

Shark fin soup.
I had it as a kid before I knew better. It's nothing special and just a status symbol at this point. There are so many other things that can substitute it and it's wild that people still pay for it.
Why?
Theoretically for the meat, sold mostly in Brazil, Uruguay, and Latin Europe*, at a comparatively low price for seafood. In practice for the fins, sold mostly in Hong Kong, Malaysia, and China.
What makes it worse is that Brazilian norms are notoriously sloppy on what you can sell as "cação" (shark or ray meat), including 40 species, quite a few of them vulnerable, and a lot of times the person buying it has no way to know. And if you tell people "only buy cação if the species is listed, otherwise you might be eating a threatened species", they'll usually whine and tell you the equivalent of "I dun unrurrstand, y buy dat one? Dis one is cheaper lol lmao".
*the link is in Portuguese but I can translate it if anyone so desires.
In addition to the reasons already mentioned, there is also a probability that the corporations operating the trawlers see sharks and other predators as competition, especially since their yields are dropping.
Who needs a bigger boat now motherfuckers?
