Dolphins are supposed to be as smart as a smart dog. How many dogs have gone extinct coz they spent too much time chasing a stick?
My problem with this, like the biofouling rules, is it's being dumped on us with no mention of any actual research to back it up. Sounds like somebody just made some stuff up and we are wearing the consequences.
Kevin you'd probably find more support on here for protecting the marine environment than the rest of the population, but these rules appear to be just dumb, they need to be sold better at the very least.
