I didn't see the program but am familiar with it and it's absolutely
terrible practice, as you say all they take is the fins and the poor sharks get dumped back into the water alive to flap around and eventually sink to the bottom and die of their injuries or by starvation
If we don't stop doing this now soon there'll be no sharks left and what's left of the ocean will become a (bigger) mess. Have any of you seen the giant squid that are rapidly marching up from Mexico and are now abundant all the way along the East coast as far North as Alaska? Those things are frightening and it looks like they can't be stopped, I bet in some years we will all be very sorry for all the sharks and whales we killed!
I'm sure if this was a more cuddly animal there would be much more commotion about it but it seems to be the problem for all fish, people can't really see them, don't really relate to them and don't really care
