#4Just think of the long term co2 savings we could make by not stopping the virus.

#5"They keep our fish stock healthy, they keep the food chain intact, they keep diseases out of other animal populations," she said. "Good luck trying to replace that when we lose them."
Isn't human predation (fishing) a suitable alternative to shark predation for this purpose? I guess they eat a more wide diet of fish types.

#6"However, the extraction of shark squalene has been a more attractive option for producers as it can cost less and yield greater quantities than nonanimal alternatives."
Now you've got my attention. How much larger are concentrations of this substance [0] in sharks when catching sharks and extracting it from them is easier than getting it from "[...] nonanimal sources includ[ing] olive oil, sugar cane, wheat germ, bacteria and yeast."

Edit: here is some information:
"[...] deep-sea sharks are targeted for the squalene market because they have some of the highest concentrations of squalene in their livers, some taking up to 20% of their body weight", from https://www.sharkallies.com/shark-free-products/cosmetics-wh...

Breatharianism [1] would solve global warming pretty quickly, within a matter of weeks, really. Anthropogenic emissions of CO2 would disappear.

Did putting in/replacing a predator in an eco system ever work? I can only think of countless examples where it didn't
