I heard about that, but didn't know that the things are so serious!They were one of the main reasons for me to visit San Diego. Truly iconic species. What a loss! Hopefully they will be around, at least.
There's still quite a lot of Giants around, just the owners have been so difficult that all the other zoos don't want to deal with them anymore. Whether this ends up with the species slowly disappearing since they'll be at one facility remains to be seen really. This highlights the problem with a species being controlled by a certain few people or a group, if things go sour the program flops.
