Core Viewpoint - The recent outbreak of toxic Karenia mikimotoi algae in South Australia's waters has been declared a natural disaster, affecting over 400 marine species and prompting a combined government response of AUD 28 million (approximately USD 18.24 million) to address the situation [1][2]. Group 1: Impact on Marine Life and Fisheries - The algae bloom has resulted in the death of more than 400 different marine species, marking an unprecedented event in South Australia [1]. - The toxic substances released by the algae affect the gill functions of fish and deplete oxygen levels in the water, leading to further marine life fatalities [1]. - The fishing industry has been severely impacted, with reports of fishermen experiencing no catches since April, leading to emotional distress among those affected [1]. Group 2: Government Response and Funding - The Australian federal government has allocated AUD 14 million (approximately USD 9.12 million) to support the cleanup of the toxic algae and related research, as well as to subsidize the affected fisheries [1]. - The South Australian government will also contribute AUD 14 million to combat the large-scale algae bloom [1]. Group 3: Environmental Factors - The algae bloom is linked to marine heatwaves affecting Australia since 2024, with sea temperatures approximately 2.5 degrees Celsius higher than usual [2]. - Factors contributing to the bloom include nutrient runoff and elevated sea temperatures, highlighting the impact of climate change on Australia's marine environment [2].
