Definition: Ocean acidification is the ongoing decrease in the alkaline level of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere.
How does ocean acidification affect the ecosystem?
Increasing ocean acidification has been shown to significantly reduce the ability of reef-building corals to produce their skeletons. This results in the decrease in reef reproduction. Therefore marine species are limited in habitats and the entire marine ecosystem is affected.
Definition: An increase in the earth's average atmospheric temperature that causes corresponding changes in the climate.
How does global warming affect the ecosystem?
A rise in temperature makes a stressful and unfitting environment to the marine species (zooxanthellae) resulting in them leaving the corals in an attempt to find a more suitable environment, this process is called coral bleaching. This affects the ecosystem as it destroys potential habitats.
Affects of another Resort on Heron Island
- Increase of boat traffic causing decrease in marine life.
- Bring more tourism affecting silver gulls, mutton birds, turtles, casuarinas, etc. Causes sand erosion and damage to the island.
- More electricity and freshwater is needed, causing the need for diggers and generators to come over to build causing pollution affecting the environment.
- Lots of people on the island swimming and stepping on coral causing destruction of the coral which will decrease the amount of coral. This will then affect the marine life as there habitats will be lost.
- Runoff will cause lots of soil in the water
- People walking or doing any activities will affect the islands natural cycle
- Larger lose of zooxanthellae
