Alien Acid Test

I read on Scientific American  yet another "oh it's worst than we thought" news, this time related with ocean acidification. There they talk about Avatar and  Acidification, but for me it's clear that this is more related with Alien. I don't see Sigourney Weaver as Dr. Grace Augustine, I see Ripley. This time Ripley, scares us again...

She forces us to choose between killing our planet or doing something to try to save it, but we must be quick, because as usual, there is no time for debate:

"I think that the science is so indisputable and easy to understand and ... we've already run out of time to discuss this," Weaver said by telephone after her testimony. "Now we have to take action."
