Did you know that the iconic Great Barrier Reef had a huge set-back this year with massive coral bleaching - the largest bleaching event on record which affected almost 1000kms of reef? The Great Barrier Reef is in trouble - over 90% was affected this year. Actually reefs around the world have been devastated by human-induced global warming.
Living simply can help make a difference. If global warming, pollution, silting are some of the key things to blame, we need to ..
reduce energy use
reduce waste - compost, cut back on plastics, recycle
eat local sustainably produced food
educate as many as possible about the issue and ways to live more simply
Industrial practices must of course also change, but rather than wait till they change, we can start immediately with what we can do, raise our awareness, raise awareness of those around us. This all helps. Speak out for the reef - use your voice for the reef and help bring about a positive change.
Global coral bleaching events are an alarming new phenomenon caused by ocean warming (more than 90% of climate change heat is absorbed by the ocean). Corals cannot withstand prolonged peaks in temperature.

Over one quarter of the Great Barrier Reef has been severely damaged and overall 93% of the reef has been impacted by coral bleaching this year. This is disastrous for the diversity of life which depends on the reef.

The Great Barrier Reef is Earth's most extensive coral reef - a World Heritage Site that we have committed to protecting. Healthy coral reefs are the most ecologically diverse habitats on earth and they also protect coasts from storms and waves. Although reefs are less than 0.1% of the world’s ocean floor, they help support around 25% of all marine species.
Please take a look at what's happening. Dr Tim Flannery says that this is a result of what we are doing to the climate, and that we need to wean ourselves off coal very rapidly.
