I'm thinking the theory is that we don't really know what a species is good for, until it's gone. For example, I don't like bees. They sting,
they are annoying. OK, I'm afraid of them. So why protect them? Well, we know that bees are helpful in pollinating plants, which helps ensure more
food for us. So, OK, leave the bees alone.
Sharks and crocs, well, we don't know exactly what good they are. None, if you happen to get eaten by one. But maybe they ensure that some other
dangerous or annoying animal doesn't get out of control.
In Australia, you know how dangerous it is to have an animal with no natural enemies. Look at all the rabbits you guys made. There's no one to eat
them, keep their numbers down, so they breed like crazy and eat your crops.
So, if the sharks or crocs were extinct, maybe there's something that would then multiply without restraint, possibly wiping out food fish, or
causing some other sort of havoc. I know in Florida alligators (also once protected) occasionally take out a chihuahua, so they do have their uses.
