If someone grabbed me out of my home and stole 30% of my blood I’d probably change my behavior too.
You’d think 30% would have seemed extreme to anyone... but there was the old problem of tragedy of the commons...when resource is owned in common, there’s a natural tendency to overuse it rather than underuse it.
Cooler heads though, once the industry became very profitable, didn’t push it too far because it just doesn’t pay to kill off what you depend on if you want to stay in business for years to come. So there was an incentive to continually try to improve methods for the sake of keeping the resource abundant.
Meanwhile, the profitable use of the crabs in a way that didn’t kill them but milked them meant a lot of research was done on these animals that otherwise would never have been carried out, and largely without the interference of environmental groups that oppose all use of animals. The unhindered research ultimately lead to alternatives and knowledge derived from it will now continue to benefit the species and all the species like Red knots that depend on it.
Not just 30% of your blood but some ding-a-ling takes it right at a time your species needs to copulate... then tosses you back out where your predators still have 100% of their blood and all their faculties.
Yeah, that would have an impact.
Glad there’s now an alternative.
