Marine stressors labels

Label

Description

Climate change

Increasing CO2 levels can lead to ocean acidification. Warming seas affect habitats. 

Nutrients

Nutrients from fertilisers and animal effluent can impact water quality. 

Contaminants

Sewage, stormwater, spills, rubbish and other urban activities can impact water quality. 

Offshore activity

Commercial fishing, dredging and oil exploration can affect fish stocks and degrade habitats. 

Overharvesting

Depleting fish and shellfish stocks affects food webs and can impact water quality.

Sediment

Erosion from land clearance can cloud the water and smother sea life.

Modifying estuaries

Removing vegetation (like mangroves), land reclamation and stopbanks can affect habitats.
