Impacts on the Great Barrier Reef: Current and Future impacts
Current impacts:
o Tourism also has a negative impact, with fragile corals broken by reef walking, dropped anchors or by boats dropping fuel and other sorts of pollution. Even people in the water with sweat and suntan lotions may contribute to the negative impact on the fragile reef environment.
o Over 2 million visit the reef each year, generating at least AU$2 billion. This makes tourism a major earner for the NE Australian economy.
Future Impacts:
o Ocean acidification will be the most significant impact to the Reef ecosystem, due to the changing climate
o Ideal environment for coral = shallow warm water with plenty of movement and light, where the water is salty and low in nutrients à Corals have died in large numbers. This is due to the rises in water temperature thought to be related to the El Nino effect
Impacts on Coral Reefs

Currency: The majority of the information presented is Charles Darwin’s theories on Coral Reefs and what role they would play and do play in our environment. His theory also suggested what would happen to the coral reefs if they weren’t cared for appropriately. The theories that are presented are those that are currently accepted and the discussion over our coral reefs are appropriate and relatable to what is happening today in our oceans.
Assumptions: The video viewed can be found on the splash ABC website. Because of this it may be assumed that all of the information is correct and that the person talking in the video is a professional. Many would also see the ABC logo, recognise the authority of the symbol and regard the information as accurate.
Main Points: These include
- That we humans are impacting the coral reefs
- First person to write a scientific study on coral reefs was Charles Darwin
- There is a key relationship between life and the rest of the planet
- Coral reefs are finely balanced eco- systems
- Composition of the sea not obvious to our sense can destroy the reefs
- Coral bleaching: when the coral begins to die
- Raised ocean temperatures (for a long period of time) can cause coral bleaching
- Global warming due to accumulation of greenhouse gases in the atmosphere
- Coral reefs can counter this effect to some extent
- Coral reefs are the most sensitive eco systems and will be the first to disappear due to global warming
Purpose: The purpose of the video is to inform and educated people about coral reefs and the part that they play in our world. Information on the impact of greenhouse gases on these environments has also been incorporated.
Evidence: Key scientists contributions have been incorporated to give authority to what is being said. These scientists include Charles Darwin, the Biologist Thomas F Gero, and Thomas Gero Junior. They all made significant discoveries concerning our understanding of coral reefs today.
Relevance: This site is quite relevant to the study of Greenhouse gases as it clearly outlines one of the effects of global warming. The site is very easy to navigate and is quick to upload. The information has been presented in a concise manner and the graphics within the video are very good.
