Ocean seagrass meadows reduce bacteria unhealthful to humans and marine organisms by up to 50 %, a new study shows, and they also decrease the likelihood of disease in coral reefs by half.
The coastal ecosystems of mangroves, seagrassmeadows and tidal marshes mitigate climate change by sequestering carbon dioxide (CO2) from the atmosphere and oceans at significantly higher rates, per unit area, than terrestrial forests (Figure 1).
