Is the ocean becoming too acidic to sustain life?

Industrial civilisation is close to breaching a seventh planetary
boundary, and may already have crossed it, according to scientists
who have compiled the latest report on the state of the world’s
life-support systems. They say ocean acidification is close to

liveability. Ian Sample speaks to Prof Helen Findlay, a biological
oceanographer at the Plymouth Marine Laboratory, to find out why
the oceans have reached this state, and whether there is anything
we can do to reverse the damage.. Help support our independent
