Oceans' Fever Means Fewer Fish

    Finding fish is going to get harder as climate change continues to heat the world's oceans. A new study finds that warming seas over the past 80 years have reduced the sustainable catch of 124 species of fish and shellfish.

    Sustainable catch refers to the amount that can be harvested without doing long-term damage to the health of populations of some species.

    Overfishing has.made that decline worse, researchers say. Overfishing refers to catching so many fish that the size of the population falls. In some parts of the world, such as the heavily fished Sea of Japan, the decrease is as high as 35 percent. That's a loss of more than one in every three fish.

    Researchers examined changes in 235 populations of fish and shellfish between 1930 and 2010. Those fish populations were scattered across 38 ocean regions. Temperature changes vary from one ocean site to another. But on average over that time, Earth's sea-surface temperatures have risen by about half a degree Celsius (0.9 degree Fahrenheit).

    On average, that warming has caused the sustainable catch to drop by 4.1 percent, the study found. About 8 percent of the fish and shellfish populations the team saw losses as a result of the ocean warming. About 4 percent of the populations increased. That's because certain species have thrived in warmer waters. One example is the black sea bass. It dwells along the northeastern U.S. coast.

    But as warming continues, even these fish will reach their limit, says Christopher Free. He works at the University of California, Santa Barbara. He led the work while he was at Rutgers University in New Brunswick, N.J.

    About 3.2 billion people worldwide rely on seafood as a source of food. That means it's urgent for commercial fishing fleets and regulators to consider how climate change is affecting the health of all of those fish in the sea.

Jawaban:

Arti darikalimat pertanyaan soal di atas adalah "Apa tujuan dari teks?".

Teks di atas merupakan Exposition Text. Teks ini bersifat persuasif dan berisi mengenai opini penulis untuk meyakinkan pembaca. Teks ini biasanya berisi isu-isu penting yang sedang hangat untuk dibahas.

Pada paragraf pertama tertulis, "Finding fish is going to get harder as climate change continues to heat the world's oceans", maupun pada paragraf akhir tertulis, "... it's urgent for commercial fishing fleets and regulators to consider how climate change is affecting the health of all of those fish in the sea". Pada kedua paragraf tersebut terdapat kata kunci yang sama, yaitu "fishing" dan "climate change".

Sehingga, tujuan dari teks di atas adalah untuk memberikan informasi tentang climate change atau dampak dari perubahan iklim untuk kehidupan di dasar laut.

Jadi, jawaban yang tepat adalah E.undefined
