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.
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.
What is the Tragedy of the Commons?
Shared resources are overused when individuals act in self-interest.
Explain the link between overfishing & ecosystem damage.
Overfishing disrupts the marine food web, affecting balance of life.
Why is biodiversity loss a concern with overfishing?
Overfishing leads to a decline in the variety of marine species.
