Part II Reading Comprehension Climate change has been blamed for killer hurricanes, sea level rise, and drought, but a new report suggests the effects of climate change might hit the world’s caffeine supply. Up to 70 percent of the world’s coffee supply could be threatened over the next 68 years, according to a new study by researchers at England’s Royal Botanic Gardens. Nearly 100 percent of the world’s Arabica coffee growing regions could become unsuitable for the plant by 2080, according to the study, published in PLOSONE . Beans from Arabica coffee plants account for about 70 percent of the world’s coffee, but the plant has to be grown under strict weather conditions:They thrive at temperatures between 64 and 70 degrees Celsius, and are highly susceptible ( 易受影响的 ) to frost or temperatures higher than 73 degrees Celsius. With temperatures estimated to increase by between 1.8 and 4 degrees Celsius by the end of the century, the fragile ( 脆弱的 ) plant might become increasingly expensive and difficult to grow, especially in places such as Ethiopia and Kenya. In that worst-case scenario, nearly all of the world’s native Arabica coffee would die out. Under more conservative estimates, about 65 percent of the regions that used to grow the coffee would become unsuitable for it. The evidence from coffee farmers, from numerous coffee growing regions around the world, is that they are already suffering from the influences of increased warming. Some commercial farmers would likely be able to move their operations to other areas or would be able to overcome climate change with artificial cooling techniques, but wild Arabica is generally considered to be much more suitable for making high-quality coffee. If Arabica becomes impossible to raise in its native areas, it could wreck havoc on the economies of the mainly third-world countries in which it grows. Coffee is the world’s most popular drink and is the second most-traded commodity in the world, behind oil. “Our modeling shows a profoundly negative trend for the future distribution of indigenous ( 本土的 ) Arabica coffee under the influence of accelerated global climate change,” the study says. “Production is likely to decrease significantly in certain areas, and especially in locations that are presently marginally suitable for coffee production.” Q1: What can we learn about Arabica coffee plants from the second paragraph?
A.
The growth of Arabica coffee plants requires strict weather conditions.
B.
The flavor of Arabica coffee is better than other’s.
C.
The Arabica coffee plants grow in the areas more subject to climate changes.
D.
The Arabica coffee plants produce more coffee beans than other coffee plants.
