All Flashcards
What is the 'Tragedy of the Commons'?
Shared resources are overused when individuals act in their own self-interest.
How does overfishing relate to the 'Tragedy of the Commons'?
Overfishing exemplifies the tragedy; a shared resource (ocean) is depleted by individual exploitation.
Explain the concept of 'sustainable fishing'.
Fishing practices that maintain fish populations and ecosystem health for the future.
Why is biodiversity loss a concern in the context of overfishing?
Overfishing can lead to the decline or extinction of certain marine species, reducing biodiversity.
How does overfishing impact marine food webs?
It disrupts the balance by removing key species, affecting predators and prey.
Explain the link between overfishing and habitat destruction.
Destructive fishing methods like bottom trawling damage seafloor habitats.
How do catch limits help prevent overfishing?
Setting quotas prevents over-harvesting, allowing populations to recover.
How do size limits promote sustainable fishing?
Allows fish to reach reproductive maturity before capture.
How do Marine Protected Areas aid in sustainability?
Restricting fishing allows fish populations to recover and thrive.
How does selective gear help?
Minimizes bycatch, reducing the impact on non-target species.
How can improved regulations help?
Better laws and enforcement protect fish populations.
What are the effects of poor fishing regulations?
Leads to overfishing, depleted populations, and ecosystem damage.
How does high consumer demand contribute to overfishing?
Increased demand drives unsustainable fishing practices and depletion.
What are the impacts of reduced fish catches?
Harder for fisherman, biodiversity loss, and ecosystem changes.
How does bottom trawling affect marine habitats?
Destroys habitats, stirs up sediment, and impacts marine life.
How do large nets affect marine life?
Cause bycatch and damage to the seafloor.
