Chemical pollution, due to the entry of oil, pesticides or heavy metals into the marine environment, the discharge of insufficiently treated sewage, the introduction of non-native species and the dumping of solid waste into the sea have been identified as other problem areas.
Tu su i problemi kao što su hemijsko zagađenje zbog prodiranja nafte, pesticida ili teških metala u morsku sredinu, ispuštanje nedovoljno prečišćenih kanalizacionih voda, uvođenje nedomorodačkih vrsta riba i bacanje čvrstog otpada u more.
