Overfishing, sea level rise, and coastal development are all significant threats to U.S. coastal ecosystems.

U.S. coastal ecosystems face multiple environmental threats that endanger their health and biodiversity. Overfishing disrupts the balance of marine life, depleting fish stocks and harming the food chain. Rising sea levels, driven by climate change, lead to habitat loss and increased flooding in coastal areas. Coastal development, including construction of resorts, housing, and infrastructure, leads to habitat destruction, pollution, and fragmentation. Combined, these threats compromise the stability and functionality of vital coastal ecosystems, affecting both wildlife and human communities.
