plus sérieusement, autre étude:

CARBON DIOXIDE, when dissolved in water, creates an acid. The continued rise in greenhouse-gas emissions means that since recordings began in the 1980s, the acidity of the oceans has risen from pH 8.11 to pH 8.06 (on the pH scale, lower numbers mean more acid). This equates to a 12% increase.
How this will affect fish is of huge concern: billions depend on them as a source of protein and for income.
A study published online today for Nature Climate Change, led by Philip Munday from James Cook University in Australia, suggests that elevated levels of carbon dioxide in seawater affect the behaviour of young damselfish and cardinalfish in a manner that may ultimately, in natural ecosystems, harm larger marine communities. Juveniles living in more acidic environments appeared oblivious to the dangers therein, acting more rashly than fish from less acidic areas as a result.
