You're supposed to use the drier AFTER you've washed your hands. In other words, you've just washed with soap and water and therefore have no germs on your hand to be blown around the room. Maybe I'm wrong and some people use the driers between using the loo and washing there hands but I certainly don't.
Firstly, all farmed cattle have been bred to be farmed. They are similar to bovines from several thousand years ago but certainly not the same any more. Breeding will have included selection for being relatively sedentary and not needing to roam a great deal. Cattle in fields do not suffer from the kind of mental issues that afflict Orcas.
The tank for an orca is significantly smaller than the equivalent field for a cow. Tanks have got bigger but they are still small for a fast moving and powerful animal.
Orcas are predators, cows are not.
Ultimately, whilst cows do have a short life, they are generally treated quite well until the point at which they are killed.
To be honest, a comparison between the way we treat cattle and the way we treat orcas is not great as they are really quite different animals.
In one other respect, Linux is also very successful - smartphones and other mobile devices. Sure, it's not the GNU/Linux we were expecting but the far is that Linux is in the palm of a lot of hands and this is still increasing.
