Rising ocean acidity slows down marine fertilization

Rising acidification of the ocean could reduce fertilization of marine invertebrates and might eventually wipe out colonies of sea urchins, lobsters, mussels and oysters, according to a study.

Scientists knew that ocean acidification was eating away at the shells of marine animals, but the new study has found that rising acidity hindered marine sperm from swimming to and fertilizing eggs in the ocean.

Climate change and the subsequent acidification of the world's oceans will significantly reduce the successful fertilization of certain marine species by the year 2100, said the report by Australian and Swedish scientists.
