example, are often referred to as the rainforests of the sea
and provide critical habitats for a wide variety of marine
life. With coral bleaching and potential mass die-offs on the
horizon, entire food chains and marine biodiversity are at
risk. To prevent the damaging effects of ocean acidification,
it is vital to focus on reducing global carbon emissions and
implementing marine protection policies immediately to
safeguard these ecosystems.
