SEA GRASS

A study in the journal Nature Sustainability, sheds light on the significant role seagrass meadows play in their ecosystems. An international team of researchers from Cornell University discovered that coastal urban seagrass ecosystems can significantly reduce human bacterial pathogens, including those with widespread antibiotic resistance, in marine bivalves — a vital food source for people around the world. This is important because the current economic burden of human infectious diseases in marine environments is estimated at $12 billion annually. Furthermore, the looming threat of antimicrobial resistance, projected to cause over 300 million deaths and cost the global economy $100 trillion, underscores the urgency of such natural interventions. 

Yes, South Africa has several seagrass meadows along its coast. These meadows, primarily made up of species such as Zostera and Halophila, can be found in various locations, particularly in estuarine and coastal areas. They play vital roles in marine ecosystems, providing habitat for various marine species, stabilizing sediments, and improving water quality. Significant seagrass habitats can be found in places like the iSimangaliso Wetland Park and near the Western Cape coastline. Conservation efforts are ongoing to protect these important marine ecosystems.
