Marine protected areas
help protect important habitats and representative samples of marine life and can assist in restoring the productivity of the oceans and avoid further degradation
. They are also sites for scientific study and can generate income through tourism and sustainable fishing.
What makes a marine Protected Area effective?
These key features were: fully
protected
(no extractive activities allowed), well enforced, old (more than 10 years), large (over 100 square kilometers), and isolated by deep water or sand.
How can marine protected areas help to alleviate the impacts of climate change?
MPAs, while not impervious to all climate change impacts, provide areas of reduced stress, improving the ability of marine organisms to adapt to climate change. Well-integrated MPA networks can increase species survival by
allowing them to move around and escape certain pressures
.
What are the cons of marine protected areas?
The disadvantages of large MPAs include
difficulties of surveillance, enforcement and monitoring of vast offshore areas
, as well as high total costs. While the cost per unit area may be lower for large MPAs, conducting surveillance and monitoring in such vast areas requires much more expensive technologies.
What effect do marine protected areas have on Environmental Quality?
Answer: They
increase environmental quality by preventing resource overuse
. Explanation: Marine protected areas are regions of the seas and oceans that are restricted from human activities.
What are examples of marine protected area?
Examples of Marine Protected areas include,
marine reserves, marine sanctuaries, national parks and wildlife refuges
.
Why marine protected areas are bad?
MPAs may actually contribute
to climate change and ocean acidification by restricting the amount of low-carbon protein available to eat
. Land-based protein is much worse for the planet than seafood.
Who enforces marine protected areas?
The land areas of these monuments are managed as national wildlife refuges by the U.S. Fish and Wildlife Service, and the marine areas (50 miles from shore of the islands) will be managed by
NOAA
. The three areas total 195,274 square miles, an area larger than any existing marine protected area in the United States.

Can a marine protected area affect biodiversity?

, which fosters resilience. Highly to fully protected MPAs have been shown to foster greater biodiversity, which is helpful to overall ecosystem health and productivity.
Can you fish in marine protected areas?
Fishing and the take of marine life such as shellfish or seaweed
is allowed in about half of California’s marine protected areas

Do marine protected areas seem to be working?
Marine protected areas, or MPAs, are an increasingly common
way of protecting marine ecosystems by prohibiting fishing in specific locations
. However, many people remain skeptical that MPAs actually benefit fish populations, and there has not yet been a way to demonstrate whether or not they are effective.
What is the difference between a marine sanctuary and a marine protected area?
A marine sanctuary is a
general type of marine protected area
(MPA). An MPA is a section of the ocean where a government has placed limits on human activity. Different types of MPAs allow different types of activities, such as scientific research, recreation, or commercial fishing.

Protected areas are controversial. To many they are essential because
their restrictions on natural resource use conserve biological systems that will otherwise be depleted
, degraded or destroyed. To critics protected areas threaten peoples’ rights and livelihoods, allowing access for some people but excluding others.
