NOAA is working to understand and address key threats to coral reef ecosystems: the impacts from global climate change, unsustainable fishing practices and pollution. The top threats to coral reefs â global climate change, unsustainable fishing and land-based pollution â are all due to human activities. These threats, combined with others such as tropical storms, disease outbreaks, vessel damage, marine debris and invasive species, exacerbate each other.

One reason is that Australia feels the effects of climate change earlier and more strongly than elsewhere.
