Whales shape their environment, just as their environment has shaped them. That's how evolution works. Evolution is nothing but the establishment of equilibria between niches and the creatures occupying those niches. When either the niche or the creature (or the number of creatures) changes, of course the other will follow suit.
The new information in this article is that scientists have discovered a way in which whales influence their environment. Engineering has nothing to do with it.
