Marine stressors
Use this interactive to identify stressors in marine environments. Drag and drop the text labels onto the microscope diagram. Selecting or hovering over a box will highlight each area in the diagram. If you hover your mouse over the text labels there is more information.
If you want to redo an answer, click on the box and the answer will go back to the top so you can move it to another box. If you want to check your answers, use the Reset incorrect button. This will reset incorrect answers only. When you are happy with your selection, use the Check answers button to check them. Use Reset all to practise again from the start.

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. |
