marine sanctuary
Definition
A marine sanctuary is an area of the ocean that is protected from human activities. This means that no fishing, mining, or other development is allowed in a marine sanctuary. Marine sanctuaries are created to protect marine life and the ocean environment.
Marine sanctuaries are designated by governments or other organizations. There are a variety of reasons why a government or organization might designate a marine sanctuary. Some common reasons include:
- To protect a specific species of marine life, such as whales or coral reefs.
- To protect an entire ecosystem, such as a kelp forest or a mangrove swamp.
- To preserve the diversity of marine life in an area.
- To provide a place for marine research and education.
- To promote tourism and recreation in a marine area.
Marine sanctuaries can be found in all parts of the ocean, from the shallow waters near the shore to the deep ocean trenches. They can be large or small, and they can be designated for different lengths of time.
Marine sanctuaries are important for a number of reasons. They help to protect marine life from overfishing, pollution, and other threats. They also help to preserve ocean ecosystems and the diversity of life that they support. Marine sanctuaries can also be used for educational and recreational purposes.
Marine sanctuaries are a valuable tool for protecting the ocean and its inhabitants. They help to ensure that future generations will be able to enjoy the beauty and bounty of the ocean.
How can the word be used?
The marine sanctuary is home to a variety of marine life, including dolphins, whales, and sharks.
Different forms of the word

Etymology
The word "marine sanctuary" comes from the words "marine", which means "of or relating to the sea", and "sanctuary", which means "a place of refuge or safety".
The word "marine sanctuary" was first used in English in the 1970s. It was originally used to describe areas of ocean that were protected from fishing and other human activities in order to conserve marine life, but it soon came to be used in a more general sense to describe any area of ocean that is protected for environmental reasons.

AQA Science Exam Question and Answer
Question:
Discuss the concept of a marine sanctuary and its significance in marine conservation. How do marine sanctuaries contribute to protecting biodiversity, preserving fragile ecosystems, and promoting sustainable fishing practices? Provide examples to illustrate the positive impact of marine sanctuaries on ocean health.
Answer:
A marine sanctuary is a designated area in the ocean that is protected by law to conserve marine life and their habitats. These sanctuaries play a crucial role in marine conservation by safeguarding biodiversity, preserving delicate ecosystems, and promoting sustainable fishing practices.
Marine sanctuaries are vital for protecting biodiversity. By providing a safe haven for marine species, they help prevent overexploitation and habitat destruction. This enables species to thrive and maintain their roles within the ecosystem, contributing to the overall ecological balance.
Preservation of fragile ecosystems is another critical role of marine sanctuaries. These areas often encompass coral reefs, seagrass beds, and other vulnerable habitats. The protection offered by sanctuaries allows these ecosystems to recover from the effects of pollution, climate change, and human activity.
Furthermore, marine sanctuaries promote sustainable fishing practices. By restricting or prohibiting certain fishing activities, these areas allow fish populations to replenish and reproduce, ensuring the long-term viability of fisheries and the livelihoods of coastal communities.
For instance, the Papahānaumokuākea Marine National Monument in Hawaii is one of the largest marine sanctuaries in the world. It protects diverse habitats and serves as a refuge for endangered species. Similarly, the Great Barrier Reef Marine Park in Australia safeguards the iconic reef ecosystem, supporting countless species and contributing to tourism and research.
In conclusion, marine sanctuaries are integral to marine conservation efforts. They serve as havens for biodiversity, safeguard delicate ecosystems, and promote sustainable fishing practices, thus playing a vital role in ensuring the health and resilience of our oceans.
