Lionfish are now all over the world spread by ballast. They have no enemies and take over any area it's introduced to, killing every other fish.
In California as well as in the Med. Grass that has been flushed from aquariums gets to the sea and covers everything in the area. The coral in the Med. is almost gone and there's nothing that can be done. They're trying in California but it's a loosing battle.
The coral around Jamaica has been reduced by 85 percent since the 30's due to pollution. Same thing in South Florida.
So what! As a species humans have the right to destroy the Earth and everything on it because we're so damn important, or is it self-indulgent? China is right, it's time to limit the amount of children one can have and bring the population down to a O growth.
Oh, no! we can't do that,,, we have the right to have as many offspring as we want. And,, if we can't pay for their intelligent upbringing someone else will.
Jeez!,,,, Sorry for the rant but it's a run away freight train that can't be stopped and the solution is so simple.
