Hectare if seagrass
prev btn next btn
Seagrasses are found on all continents, except Antarctica. To date, more than 70 species of seagrasses have been recorded. Soberingly, a study by the University of California found that almost 15% of these are now considered threatened due to habitat loss and degradation, driven by rapid development and pollution. Seagrasses are thought to be one of the most rapidly declining ecosystems in the world. It is estimated that 29% of global seagrass has been lost and if trends continue, another 20-30% could be lost in the next 100 years. Furthermore, IUCN estimates that seagrasses are responsible for storing about 15% of the total carbon stored in the ocean. Furthermore, they can bury that carbon in the seabed 40 times faster than tropical forests bury it in soil.
