Intro
Discover how US territorial waters impact the environment in 5 significant ways. From marine pollution and habitat destruction to ocean acidification and climate change, explore the profound effects of human activities on our nations aquatic ecosystems, including coral reefs, sea life, and coastal communities.
The world's oceans cover over 70% of the planet, and the United States has a significant stake in these waters. The US has the second-largest Exclusive Economic Zone (EEZ) in the world, covering an area of approximately 3.4 million square miles. This vast territory is not only crucial for the country's economy but also plays a vital role in the health of the environment. In this article, we will explore five ways US territorial waters impact the environment.
What are US Territorial Waters?
US territorial waters include the 12-nautical-mile territorial sea, the contiguous zone, and the EEZ. The territorial sea is the area extending 12 nautical miles from the coastline, where the US has sovereignty and jurisdiction. The contiguous zone extends 24 nautical miles from the coastline, where the US has jurisdiction over activities that affect its territorial sea. The EEZ extends 200 nautical miles from the coastline, where the US has the right to explore and exploit natural resources.
Impact on Marine Life
US territorial waters are home to a diverse array of marine life, including fish, mammals, and invertebrates. The country's EEZ is one of the most biodiverse regions in the world, with over 2,000 species of fish and invertebrates. However, human activities such as overfishing, pollution, and coastal development are threatening the health of these ecosystems.
1. Overfishing and Depletion of Fish Stocks
Overfishing is one of the most significant threats to the health of US territorial waters. Many fish stocks are overfished or depleted, which can have cascading effects on the entire ecosystem. For example, the depletion of cod stocks in the Gulf of Maine has led to a decline in the population of cod-dependent species such as seals and seabirds.
Conservation Efforts
To address overfishing, the US has implemented various conservation efforts, including catch limits, closed areas, and marine protected areas. The Magnuson-Stevens Fishery Conservation and Management Act is the primary legislation governing fisheries management in the US. The act requires fishery managers to set catch limits and implement conservation measures to prevent overfishing.
2. Pollution and Climate Change
Pollution and climate change are two of the most pressing environmental issues facing US territorial waters. Pollutants such as plastics, chemicals, and nutrients from land-based activities are harming marine life and ecosystems. Climate change is also having a profound impact on US territorial waters, with rising sea levels, ocean acidification, and changes in water temperature affecting the distribution and abundance of marine species.
Examples of Pollution and Climate Change Impacts
- The Great Pacific Garbage Patch, a massive accumulation of plastic debris, is located in the North Pacific Ocean, which is part of the US EEZ.
- The 2010 Deepwater Horizon oil spill, which released an estimated 4.9 million barrels of oil into the Gulf of Mexico, is one of the most significant environmental disasters in US history.
- Rising sea levels are causing coastal erosion and flooding in low-lying areas, such as the Chesapeake Bay and the Gulf Coast.
3. Coastal Development and Habitat Destruction
Coastal development, such as the construction of seawalls, jetties, and piers, is leading to habitat destruction and degradation in US territorial waters. These structures can alter natural sediment transport processes, disrupt marine habitats, and block the migration of species.
Examples of Coastal Development Impacts
- The construction of the seawall in Miami Beach, Florida, has led to erosion of adjacent beaches and loss of habitat for sea turtles.
- The development of offshore wind farms in the Atlantic Ocean is raising concerns about the impact on marine life, particularly birds and bats.
4. Shipping and Navigation
Shipping and navigation are critical components of the US economy, with millions of tons of cargo and thousands of vessels passing through US territorial waters every year. However, these activities can have significant environmental impacts, including oil spills, habitat destruction, and introduction of invasive species.
Examples of Shipping and Navigation Impacts
- The 2012 grounding of the cargo ship Rena off the coast of New Zealand highlights the risks of shipping accidents in US territorial waters.
- The introduction of invasive species, such as the zebra mussel, has had devastating impacts on native ecosystems in the Great Lakes.
5. Tourism and Recreation
Tourism and recreation are significant contributors to the US economy, with millions of people visiting US territorial waters every year. However, these activities can have environmental impacts, including habitat destruction, pollution, and disturbance of marine life.
Examples of Tourism and Recreation Impacts
- The development of coral reefs for tourism in Hawaii has led to concerns about the impact on these fragile ecosystems.
- The increasing popularity of whale watching in US territorial waters is raising concerns about the disturbance of marine life.

In conclusion, US territorial waters play a critical role in the health of the environment. The impacts of human activities, such as overfishing, pollution, and coastal development, can have far-reaching consequences for marine ecosystems. It is essential that we take steps to mitigate these impacts and work towards sustainable management of US territorial waters. We encourage you to share your thoughts on the importance of protecting US territorial waters and the actions we can take to ensure their health for future generations.
