The marine life at one of Australia’s biggest tourism drawcards is under threat with more than 500 reef-based species of fish, seaweed, coral and invertebrates on the decline.

Decline of Australia's marine species

Marine sanctuaries are supposed to protect ocean life but what can they do when this life moves away as climate change heats our planet's seas, many marine species are permanently migrating in the search of cooler habitats.

WION Climate Tracker: Marine life flee warming oceans; climate change heats planet's seas

<p>Climate change and global warming are indeed detrimental to the well-being of our planet but just how dangerous can it be for the life has been thrown light upon by a scientific study. Researchers from Bedford Institute of Oceanography in Nova Scotia have concluded that if emission of greenhouse gases continue with 'business as usual' approach, nearly all marine species would face risk of extinction by the end of 21st century.&nbsp;</p>

<p>For this study, the researchers studied threat faced by nearly 25,000 marine species. They found that almost 90 per cent of these species will be at risk of extinction by the end of this century. The species that the researchers studied included plants, animals, bacteria, protozoans and chromists.</p>

<p>Daniel Boyce, an ecologist at the Bedford Institute of Oceanography, and author of the study said that the findings are "quite startling and very sobering". He was quoted by ABC News.</p>

<p>"I'd like to think that that's an implausible scenario," Boyce said. "But nonetheless, it is the worst-case scenario. And when we evaluated that scenario, we found that there was a very grim picture for the climate risk for marine species."</p>

<p>Such a large percentage of marine life facing extinction may create huge problems for the global ecosystem.&nbsp;</p>

<p>It is well known that food chains and food webs are interconnected across the biosphere on Earth. A tectonic shift, such as predicted by the study may surely spell trouble for all life on the planet.</p>
