Now we have something even more serious that we just don't know about.
As a yachtsman explained after crossing yet another ocean:
Exactly 10 years before, when Newcastle yachtsman Ivan Macfadyen had sailed exactly the same course from Melbourne to Osaka, all he'd had to do to catch a fish from the ocean between Brisbane and Japan was throw out a baited line.
"There was not one of the 28 days on that portion of the trip when we didn't catch a good-sized fish to cook up and eat with some rice," Macfadyen recalled.
But this time, on that whole long leg of sea journey, the total catch was two.No fish. No birds. Hardly a sign of life at all.
So where did the fish go? As the article goes on to say, a mixture of pollution, over-fishing and even more pollution. We're not talking about beer can plastic getting stuck around the necks of penguins or big fish getting caught in illegal nets, this is much worse, this appears to be the systematic rape of the oceans. And no-one seems to be doing anything about it.

How the hell are we going to fix this one?
