Genetic Study Provides Estimate of Whale Populations
ChopsMIDI writes "Many more whales were hunted in the 18th century than thought, a genetic study of the North Atlantic animals suggests. U.S. researchers say the International Whaling Commission may be underestimating by tenfold the number of whales in the seas before hunting began."
If you can make it profitiable for companies to invest in breeding a speices, that speices will thrive. Horses would probably be extinct now if there weren't people intentionally breeding them for recreational use. I don't know enough about breeding whales to speak to this issue specifically, but I do know that there are probably a lot of creatures on this planet that thrive only because of economic motivation.
