saving the great barrier reef By Jake Mussared

Australia’s most celebrated natural treasure is under siege. The Great Barrier Reef is in a desperate struggle to survive the impact of human development.

The Australian Great barrier reef is one of the seven natural wonders. It is the largest natural reef system and also the largest living structure. It is 344,400 square metres, making it visible from space. It is a place of beauty, also providing many Australians with a livelihood, supporting a $5 billion a year industry. But is this the only way we should value the reef? The Great Barrier Reef is one of the true wonders of the planet, however, thanks to climate change and development it is at risk. Do we simply ignore any concern for the environmental degradation and species lost and put the interest of humans and the economy first? The reason the great barrier reef is under threat is because of global warming. Global warming heats the water, causing the algae living inside to leave the coral, causing the coral to lose its energy, turning it colourless or "bleaching" it. The temperature of the water the coral lives in only needs to be a few degrees warmer than usual to cause coral bleaching. Each year a large amount of coral die because of bleaching, due to the loss of energy in its tissues. It takes 15 years for the faster growing corals to regenerate and even longer for the slower growing ones. Already two thirds of the reefs coral is dead!

As shipping increases along the reef, a central question is raised, how much local development is to much? Fly over Hay Point, just south of Mackay, on any day, and you will be confronted by the same picture every time. Ships lined up, kilometres out towards the horizon, and through the reef area, waiting their turn to pick up tonnes of coal. So how does this coal affect the reef? The coal is shipped away to burn in power stations which produce pollution in the form of carbon dioxide, a greenhouse gas. This gas traps heat in the atmosphere causing the planet to heat up. For the reef this means the water temperatures are rising, leading to the the bleaching effect. So why don't we stop and let the reef regenerate. We can have coal or the reef, but not both.

Persuasive techniques: repetition(alliteration), rhetorical question, adjectives, facts, emotive language.

Reflection: I think the main part I’ve done well in the task is the text because it covers more than one argument about the topic giving a wider range of information making it more likely to persuade the reader. The help I needed during the task was with becoming familiar with all the aspects of photo shop needed to create an original image. If I had to do the task again I would change the persuasive techniques in the text making them more advanced making it easier to persuade the reader. The main thing I learnt from the task about persuasion is that text is not the only nor strongest type of persuasion in advertising. Images can be just as powerful because they can include small amounts of text coloured to represent something or make people feel an emotion, making them more likely to be persuaded.
