I've been telling my hubby for years that's it's more difficult being female! LOL

There was a big stink over here about the Japanese when they found out they'd been catching the tuna in our waters. Hope it's not leading to a collapse!

The largest danger facing the coral is the bleaching associated with higher temps from the expulsion of their zooxanthellae. They really have no way of dealing with the higher temps, because the majority of zooxanthellae can't tolerate the higher temps.

This might be helpful for coral facing other pressures such as pollution and overgrazing though.
