Over the next hundred years on the planet can happen complete extinction of crabs. Along with the steady increase in the average temperature on Earth is increasing the acidity of the water in the oceans. That was the conclusion British oceanographers at the last observation, which lasted several years.
As the researchers say, this trend is not very favorable conditions for crabs, clams and lobsters. Due to the negative effects of acid is the destruction of their shells, so that they become quite easy prey for predators.
According to the researchers, in the middle of this century, marine crustacean could become extinct in the southern and northern parts of the ocean, with a hundred years they may disappear completely.
