A "dolphin jail" !!! maybe it is a little like that, but think on all the positive thinks that this kind of parks create! children getting crazy about the animals, and everybody is telling them that this nice animals getting kild in some part of the world for stupid reasons!
I think it is a verry small price to pay to have a few dolphins etc, in captivity to learn people about them.
Offcourse the way that the animals getting treated and the size of the tanks etc is verry important but in this times even the realy commercial guys that are trying to make money from this animals have to make sure everthing is more then OK! or it wil blow up in there face!
And if i have to chose between 10 people making money on this way from animals instead of 1 guy killing animals for money, i know what i am choosing :-)
There is no perfekt World so we need to make it so close to perfekt as possible, and if we need this kind of parks to learn the people about nature and animals then i am more then OK with them!
sorry for my english (talking and reading is much easier then writing it :-)
