According to the article, jellyfish are invading the oceans near JAPAN. Fisherman in the area assert that the amount of fish and jellyfish in the waters have shifted drastically during their lifetime. 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. Also humans building docks, bridges, and other water infrastructures have led to a decline in habitat availability for jellyfish.
Answer:
to provide ports to the ocean
Explanation:
East Africa is a region that has several large lakes, located on the line of divergence between the Somali and Nubian plates, better known as the East African rift. These lakes are very important for the people living in the region. They are very rich in fish, so they provide lot of food. Because hey are large, they are also used for transportation and trade. There are other usages of them as well, such as the production of hydroelectric power, and providing water for irrigation of the agriculture. These lakes though are not connected to the oceans, so the ports are not providing any access to the oceans.
