There is a large abundance of jellyfish (making it difficult or impossible to fish some days) and a small number of other kinds of fish.
Humans may have caused this problem by over-fishing disrupting the balance of the underwater ecosystem. Jellyfish are eaten by some fish and compete with other species of fish.

Answer:
The correct answer is C. This maps represents the triangle trade.
Explanation:
The triangular trade was a slave trade in which manufactured goods such as alcohol, metal containers, clothing and firearms were transported from Great Britain (especially Liverpool). Cargo transported in Africa was exchanged for slaves transported to America or the West Indies. The slaves were replaced with sugar, cotton, rum and tobacco. For the shipowner, the deal was risky but very profitable. Each stage was profitable and the cost of the ship could be recovered in just a few trips. The triangle trade was practiced on a full scale since the 17th century and reached its peak in the late 18th century.
Answer: D) eliminates the need for trade with other nations
Explanation:
Having comparative advantage on the production of a good or service means that a country can produce that good or service cheaper and be able to exchange it for other goods and services that other countries are offering.
International trade is therefore very important to countries acting on comparative advantage because the country will not produce all that it needs but rather what it is good at producing. This means that trade with other countries is still needed to provide those goods that they need but find it expensive to produce.
