Estuaries and wetlands are one of the ecosystems most threatened by development, however they trap (sequester) more carbon than rainforests. Both seagrasses and salt marsh grasses are incredibly productive carbon sinks, as the carbon they use to make their leaves are incorporated into the layers of sediment every year.
Estuaries and wetlands also help to make our water cleaner, as they act like a giant liver that filters and traps toxic chemicals and nutrients. They are hotspots for biodiversity, and are vital as habitat for migrating birds, and nurseries for juvenile fish. Routing this natural gas pipeline through this sensitive estuary habitat is an unacceptable risk.
