Destructive fishing practices
Trawling, blast fishing, and other harmful types of fishing destroy shallow seas habitats, tearing up seagrass beds, shattering coral reefs, and wiping out mangrove forests. These fragile ecosystems can take a very long time to recover, if they ever do.
Coastal development, sea-filling, and pollution
Unchecked real estate development and other land-based human activities are a major concern. Chemical run-off from construction projects, sea-filling to create more space to build on, and (in the water) aquaculture can all have a devastating effect.
Weak or nonexistent management practices
Many governments and communities lack the information and tools they need to strike the right balance between using and conserving coastal marine ecosystems.
Lack of awareness
There is little public or political awareness of the value or fragility of our shallow seas, and even less coordinated action for their survival.
