Scientists say that although some effects of the pollution are already visible we have not seen it all.
Water quality in Samish Bay had a lot to suffer over the years. Workers that harvest oysters during a low tide here noticed some oysters no longer develop their protective shells. Scientists analyzed this situation and found out that the water’s rising acidity is to blame.
Under the microscope baby oysters seemed normal. Scientists needed several years to figure out that the reason why oysters died at a young age was that as larvae they didn’t form protective shells.
The current situation should trigger an alarm. The rising acidity of our oceans endangers all marine animals and thus us indirectly.
