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.

Arti dari pertanyaan soal ini adalah "Mengapa penting untuk terus menangkap ikan dengan tangkapan yangberkelanjutan?" Ada kata kunci yang dapat dilihat dikalimat pertama pada paragraf kedua, " Sustainable catch refers to the amount that can be harvested without doing long-term damage to the health of populations of some species ." yang mana memiliki arti penangkapan yang berkelanjutan merujuk pada jumlah yang dapat dipanen atau diperoleh tanpa merusak kesehatan populasi beberapa spesies dalam jangka panjang" Jadi, jawaban yang tepatadalah A.
