1 By releasing carbon dioxide to the atmosphere,
humans are rapidly altering the chemistry of the ocean
and affecting marine life. The acidity of the ocean has
4 increased by about 25% since before the Industrial
Revolution, greater than any other time within the last
two million years. Given the speed at which humans are
7 altering ocean chemistry, marine plants and animals may
not have time to adapt or migrate as they did in the past.
Because of acidification, marine life faces a
10 two-fold challenge: decreased carbonate availability and
increased acidity. Laboratory studies suggest changing
ocean chemistry will 1) harm life forms that rely on
13 carbonate-based shells and skeletons, 2) harm organisms
sensitive to acidity and 3) harm organisms higher up
the food chain that feed on these sensitive organisms.
16 However, we do not yet know exactly how ecosystems
will be impacted.
