what are some threats to the coral reef ecosystem
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.
