This video shows the natural ecosystem of the Barrier Reef, and the effects that humans can make on the Reef, and also the biotic and abiotic factors. It says that we as a community we are over fishing, which means that we are catching too many fish from the environment and that we are dumping to much rubbish and that we are polluting the waters. We need to stop this because our reefs are now in danger. This source is useful because this is exactly what I am focusing on due to human impact in the Great Barrier Reef. It has shown me useful pieces of information, like how there are many species of sea creatures, and that we need to be careful about how we treat our environment, and how we take care of the species that live in it. The source is also reliable because it shows true stuff on what is happening to our reefs, and also how the ecosystem is being affected by our actions.
This is an article about Global warming and how it is effecting the Great Barrier Reef. It reads 'the Intergovernmental Panel on Climate Change presented strong evidence that global warming over the last century was largely a result of human activity. This is unacceptable, not only do we need to stop polluting the environment, but we need to pick up any rubbish that we see, and to use renewable energy so we don't pollute the world with fossil fuels. The article also states that Climate models indicate that the sea surface temperature is expected to rise by 1 to 3 degrees, while the sea level is expected to rise by 0.18 to 0.79 metres. Regional weather patterns are likely to change, resulting in an increase in the severity and frequency of storm events, particularly cyclones'. We need to prevent these things happening to our oceans, as they will affect the ocean's ecosystem, and also our biosphere. This is a useful source because it gives you incredible pieces of information about how global warming can affect on our coral reefs, and also the marine environment. It is a reliable article because at the top of the page it says that it is a Trusted Online Research. It also gives good information on the topic that I was researching about.
The functions of coral reefs, the importance of healthy ecosystems and the advantages of biodiversity. This website specifically focuses on BioDiscovery, which is the collection and use of native biological material (e.g. plants, animals and other organisms), and the Great Barrier Reef. It says that some risks to the reef is the impact of anchor damage, over fishing, coral diseases, cyclonic weather and deep sea trawling. There are some species of fish that are directly affected by the loss of living coral, like the butterfly fish, damselfish and the coral goby. It shows that if coral has died, or has been bleached, then it impacts on other species of sea creatures. This is a useful website because it shows how coral reefs and some species of fish are being affected by the loss of the coral reefs. It could be more useful if it showed the other species in danger from coral loss. It is a reliable source because the maker of the website is a company called BioDiscovery, which is focused on genetic research and genomic analysis, so it is a real and legit source. It is also reliable because impacts on the reef is what I am researching about.
This is a very powerful photo demonstrating the effects of bleaching on coral in our reefs. Warmer water temperatures can result in coral bleaching. When water is too warm, corals will expel the algae, which is called zooxanthellae, living in their tissues causing the coral to turn completely white. Corals can survive a bleaching event, but they are under more stress and are subject to mortality, but not all bleaching events are due to warm water. There was one case in Florida Keys where the temperature of the water had dropped eleven degrees lower than the average water temperature, causing coral to bleach and result in some coral death. This is a useful photo because it can show the human impact that is happening to our reefs. It is also useful because it shows a before and after photo on what is going on. This source is not exactly reliable because it doesn't say where the reef is, and it also doesn't say how the coral ended up this way.
The cumulative effect of these threats weakens the Reef’s resilience, affecting its ability to recover from serious disturbances predicted to become more frequent in the future. This website informs the readers about the threats about the natural wonder of the great barrier reef. It shows that climate change, poor water quality, coastal development, and over fishing puts our reefs in danger. It also provides some useful videos from David Attenborough about how our reefs are in danger, and also another video to see if reefs can recover. These videos show an amazing amount of wildlife in the sea, and it shows that these animals and plants can be affected by our actions. The good news is that coral reefs are naturally resilient. By reducing threats and minimizing impacts we enable reefs to naturally recover, even from the most damaging of tropical cyclones, such as Cyclone Yasi in 2011. This is a useful site because it shows the impacts and threats from human activity, and how it is affecting our reefs and marine life. It also shows little facts about how we can save our reefs and stop coral from dying. This is a reliable source because this is a real foundation on trying to protect the environment, and it is also a .org site, meaning that it is a real organisation. It is reliable because it says real facts and evidence, and they are not just making it up.
