This article suggests that climate change could make some marine life such as lobsters bigger. A study has shown that more acidic oceans caused by rising atmospheric carbon dioxide can produce oversized shelled marine species including lobsters, crabs and shrimps. Whilst this may be good news for seafood lovers there is some bad news. Other species such as oysters, scallops and clams suffer in more acidic waters because they are unable to build their shells. Lobsters on the other hand thrive under higher CO2 levels because they can convert inorganic carbon in seawater into a form they can use to produce shells. However, they rely on the smaller creatures for food so in a situation where the predator is getting stronger and the prey weaker it seems only a matter of time before the predators are also severely impacted and the population becomes unsustainable.
