I feel this task has been pretty successful, everything was organised and we were never short of things to do, all our work was done effectively and we were very efficient. x

I have enjoyed doing this task, I have learnt a lot more about coral reefs, and could hopefully answer an exam question that's more focused on this. it was a good team as we got the work done quickly and efficiently and Ben was a very good leader as he was very organised and made sure we got the work done and still had a bit of fun.

Had some good fun learning about coral reefs and I really enjoy the challenege tasks as everyone must meet the set deadline. The videos were good to make and the whole team worked well together.

I think this task went well as our PM gave clear instructions on what tasks to carry out and we managed to get all of our work completed on time for the the deadline. I was in charge of the team blog and writing up about the pressures of the coral reef and how it is being damaged by human factors and environmental.

The Great Barrier Reef is the world’s largest coral reef system, composed of over 2900 individual reefs and 900 islands stretching to just over 2,300 kilometres. The reef is located in the Coral Sea, off the coast of Queensland Australia.

The Great Barrier Reef is subject to two million visitors every year and furthermore generates $5-6 billion per year. Despite this however tourism does generate many problems for the Great Barrier Reef. One problem caused by tourism is the use of anchoring damaging the reef and disturbing natural homes for whales and dolphins. Furthermore the collecting of coral damages the reef and destroys habitats. Also overfishing in the area reduces the fish population and outboard engines further pollute oceans. Warmer ocean temperatures put stress on coral and lead to coral bleaching. The Great Barrier Reef has experienced two mass coral bleaching events in 1998 and 2002. Bleaching was more severe in 2002, when aerial surveys showed that over 50% of reefs experienced some coral bleaching.

Declining water quality is a major factor in the pollution of the Great Barrier Reef. During tropical floods, runoff containing fertilizer and pesticides is dispensed into the reef's waters and harms its delicately balanced ecosystem. The runoff problem is made worse by the loss of coastal wetlands along the Queensland coast, which act as a natural filter for toxins. The area of wetlands in the Great Barrier Reef catchment has decreased by over 50 percent.

The Great Barrier Reef supports a vast array of life forms. Thirty species of whales, dolphins and porpoises have been recorded in the Great Barrier Reef, More than 1,500 fish species live on the reef, including the clownfish, red bass, red-throat emperor. The Great Barrier Reef is home to 215 species of birds.

It's been good to go over coral reefs again, as I have still learnt knew things about the dangers of tourism. Ben gave everyone jobs and was a great leader. Working on this challenge question in a group was a very efficient way of learning as it gets all the information quicker as well as all in the same place.

I have enjoyed doing this task today. Ben was a really organised team leader which helped witht the tasks. We got te work done quick and were really efficient.  The tasks were set out well and gave us a good structure so we could complete the tasks on time and within the deadline set.

What are the positive and  negative effects from tourism on coral reefs?

# data[].attributes.body
Coral reefs occur along the coastline inbetween the tropics, the water must be clear, warm and clean from pollution for the ecosystem to flourish

# data[].attributes.body
. Pollution is a large factor leading to the decline of coral reefs due to oil spills, dumping and tourism such as emissions from dive boats and hotels.
. species of coral becoming extinct means habitats for marine species of fish become sparse
. by late 2000's, 27% of the world's coral reefs were destroyed
. 11% of the worlds reefs are left due to human factors.
