Methane is responsible for about 16 percent of global greenhouse gas emissions. That doesn’t seem like much, but experts warn that methane is over 20 times as powerful as carbon dioxide in trapping the sun’s heat in the atmosphere. Where does all the methane come from?

Much of the methane in the atmosphere is released naturally in damp areas. _____________, about 15 percent is emitted by the growing number of cows and pigs. Statistics vary about the exact amount of methane emitted by a cow, but it is generally agreed that a single cow releases up to 120 kilograms of methane per year, more than any other domestic animal. That is about 1,000 times the amount of methane emitted by an average person.

[13~15] 다음 글을 읽고, 물음에 답하시오.

(A) Livestock is said to produce 130 times as much manure as humans in the U.S. When not managed properly, the manure and water containing i t cause severe harm to the ecosystems of rivers and oceans. When rain comes, manure is washed away with the runoff, polluting nearby soil, streams, and rivers all the way until it reaches the ocean.

(B) Once it reaches the ocean, it contributes to the formation of what is known as a “dead zone.” Dead zones occur around the world, primarily near areas where heavy farming and industrial activity spill nutrients into the water. Concentrated levels of nutrients in water result in the blooming of algae, which are simple forms of water plants. When too many plants grow in the water, they use up the ocean’s oxygen, suffocating other plants and animals. The largest known dead zone occurred in the Gulf of Mexico in 2002, when runoff from the

Mississippi River caused over 20,000 square kilometers of the Gulf area to become uninhabitable for oceanic life.

(C) As more people want more meat, it is inevitable that land for livestock be extended to meet the demand. More meat production results in increased water pollution in both rivers and oceans since cows and pigs eat a lot and at the same time produce a lot of manure.
