Final answer:
Overfishing in coastal areas has had negative impacts on local economies and the marine ecosystem. Scientists are helping these communities by working on strategies to restore fish populations and promote sustainable fishing practices.
Step-by-step explanation:
Overfishing in coastal areas has led to the struggle of many communities that depend on fishing for their local economies. The collapse of fisheries not only affects human populations that rely on fishing for employment and income, but also leads to a radical restructuring of marine ecosystems. When a dominant species is over-harvested, it can have long-lasting effects on the food chain and the overall health of the ecosystem. Scientists are working with these communities to reestablish fish populations and create sustainable fishing practices.
