Marine Ecosystems

Marine ecosystems could be fundamentally altered by ocean acidification which would have a significant impact on fisheries.

Coral reefThis could cause substantial loss in revenue and jobs. The loss of coral reef habitats due to acidification may seriously affect many commercial fish species and could prove disastrous for coastal communities relying on subsistence fishing of reef species.

In addition to acidification, the rise in ocean temperatures also has the potential to negatively impact both coral reef habitats and fish populations.
