To put it into context, an orca would have to swim 1,500 lengths of the planned enclosure to swim as far as he would each day in the wild. And while wild orcas dive up to 1,000 feet below the ocean's surface, the new pools would only be 50 feet deep.
And these slightly bigger tanks could soon be just as cramped, as SeaWorld has acknowledged on its website that it intends to breed more orcas if the expansion is improved.
Some of the so-called improvements made to the tanks will also be more for the benefit of the humans than the orcas, such as a newly decorated viewing experience. And many people have rightly pointed out that if SeaWorld cared about orcas, it would spend the $100 million it plans to use on this new tourist attraction on sea pens - an alternative endorsed by many welfare-minded biologists - or conservation, which SeaWorld often talks about but rarely contributes to.
