Clearing mulga woodland in Queensland to open up land for cattle during drought.
We're going to have to adapt to climate change, but some of the options on the table could do more harm than good if they destroy the ecosystems that protect us.
The land may be dry, but Western Australia’s waters are full of life.
The Great Barrier Reef might get all the attention, but what about our western coral reefs? Warmer waters and human impacts mean these reefs are in trouble.
Scuba diving must be done in a sustainable manner to preserve the industry.
Africa has a number of excellent scuba diving sites, but these must be maintained sustainably to keep attracting different divers.

Corals are under threat from warming seas, and new research shows that even the toughest corals will suffer.

Many corals can't make it through the bleaching events caused by warming ocean waters. But some can – and scientists are trying to learn more about the sources of their resilience.
Nutrient runoff is one of the major contributors to crown-of-thorns outbreaks.

Despite 15 years of concerted action by the Australian and Queensland governments the health of the reef is not improving and in fact may be continuing to deteriorate.
Soon the oceans will be too warm to support thriving coral reefs.

Corals are experiencing only the third global bleaching event in recorded history, caused by warming seas. But worse is yet to come.
The reefs of Indonesia - part of the Coral Triangle - could lose many of their species thanks to climate change.
How will climate change affect life in the oceans? New research shows that the answer is likely good and bad.
Diving in Indonesia’s Raja Ampat Marine Park to see these clownfish will cost you more than before – but for good reason.
Diving in many parts of Indonesia, Thailand and Malaysia now costs a little more than it used to – but you might be happy to discover why.
The Great Barrier Reef is one of the most magnificent wonders of our world.
With the United Nations set to decide on whether to list the Great Barrier Reef as officially in danger, we look at the various threats to the reef's survival, starting with the biggie... climate change.
Give up, brain coral, we have you surrounded.

With their natural predators removed, sponges are free to take over coral reefs.
Coral reefs and associated fisheries are of vital social, cultural and economic importance.
Scuba-diving scientists devise method for gauging the health of coral reefs – a vital ecosystem for keeping fisheries sustainable for people.
Climate change is affecting gender ratios in fish, and could hamper their ability to return to a 50:50 balance.
Warmer temperatures can throw off the gender balance in some species. But some fish can adjust their offspring's gender to compensate, but only if temperatures don't rise too high.
The World Heritage Committee has called for a comprehensive assessment not just of the threats to the Great Barrier Reef, but of their cumulative effect.

The government says it has met all of the recommendations for safeguarding the Great Barrier Reef. But a close reading of the dozens of UN recommendations shows that many have been only partly fulfilled.
There are more and bigger coral trout in parts of the Great Barrier Reef closed to fishing.
Fishing is a major threat to the Great Barrier Reef, but new research shows that areas closed to fishing just over a decade ago are home to bigger and more fish.
Coral reefs, the rain forests of the sea.
A new ecology study doesn’t focus on how people degrade the environment. Instead, it untangles the way physical factors in a pristine ecosystem drive the biology of what lives there.
Kelp covered landscape in Western Australia.
Western Australia’s marine environment is unique. Two world heritage areas, the largest fringing coral reef in Australia, and more than a thousand kilometres of underwater forests, supporting incredible…
One species, two colours.
The stunning colours of coral attract many divers to the world’s reefs but, for us coral scientists, one mystery has always remained. Swimming over a reef, you can frequently spot brightly coloured coral…
During an outbreak, crown-of-thorns starfish can number in the millions and decimate coral reefs.

Crown-of-thorns starfish are one of the biggest threats to the Great Barrier Reef. Since 1985, the Great Barrier Reef has lost half its coral cover, with almost half of this coral loss due to the crown-of-thorns…
Looks healthy, but still lacks the big predatory fish… how would it rate on the index?
We know that fishing has significant impacts on our oceans and the animals that live in them. Effects can range from habitat modification caused by bottom trawls, stock declines from overfishing or subtler…
