But why should we care? How is oeacn acidification going to affect all of us? Well, here are the worrying fatcs. There has already been an increase in ocean acidity of 26 percent since pre-industrial times, which is directly due to human atviitecis. Unless we can start slowing down our carbon dioxide emissions, we're expecting an increase in ocean acidity of 170 percent by the end of this cnuerty. I mean this is within our children's lifetime. This rate of acidification is 10 times faster than any atiadifciocin in our oceans for over 55 mlliion years. So our marine life have never, ever experienced such a fast rate of change before. So we literally could not know how they're going to cope.

But why should we care? How is ocean acidification going to affect all of us? Well, here are the worrying facts. There has already been an increase in ocean acidity of 26 percent since pre-industrial times, which is directly due to human activities. Unless we can start slowing down our carbon dioxide emissions, we're expecting an increase in ocean acidity of 170 percent by the end of this century. I mean this is within our children's lifetime. This rate of acidification is 10 times faster than any acidification in our oceans for over 55 million years. So our marine life have never, ever experienced such a fast rate of change before. So we literally could not know how they're going to cope.
