问题         With the global population predicted to hit close to 10 billion by 2050, and forecasts that agricul¬tural production in some regions will need to nearly double to keep pace, food security is increasingly making headlines.In the UK, it has become a big talking point recently too, for a rather particular reason: Brexit.
        Brexit is seen by some as an opportunity to reverse a recent trend towards the UK importing food.The country produces only about 60 percent of the food it eats, down from almost three-quarters in the late 1980s.A move back to self-sufficiency, the argument goes, would boost the farming industry, political sovereignty and even the nation’s health.Sounds great—but how feasible is this vision?
        According to a report on UK food production from the University of Leeds, UK, 85 percent of the country’s total land area is associated with meat and dairy production.That supplies 80 percent of what is consumed, so even covering the whole country in livestock farms wouldn’t allow us to cover all our meat and dairy needs.
        There are many caveats to those figures, but they are still grave.To become much more self-sufficient, the UK would need to drastically reduce its consumption of animal foods, and probably also farm more intensively—meaning fewer green fields, and more factory-style production.
        But switching to a mainly plant-based diet wouldn’t help.There is a good reason why the UK is dominated by animal husbandry: most of its terrain doesn’t have the right soil or climate to grow crops on a commercial basis.Just 25 percent of the county’s land is suitable for crop-growing, most of which is already occupied by arable fields.Even if we converted all the suitable land to fields of fruit and vegetable—which would involve taking out all the nature reserves and removing thousands of people from their homes—we would achieve only a 30 percent boost in crop production.
        Just 23 percent of the fruit and vegetables consumed in the UK are currently home-grown, so even with the most extreme measures we could meet only 30 percent of our fresh produce needs.That is before we look for the space to grow the grains, sugars, seeds and oils that provide us with the vast bulk of our current calorie intake.
Some people argue that food self-sufficiency in UK would ________.

选项 A、be hindered by its population growth
B、become a priority of the government
C、pose a challenge to its farming industry
D、contribute to the nation’s well-being

答案D

解析 根据题干关键词self-sufficiency定位到第二段倒数第二句“A move back to self-sufficiency, the argument goes, would boost the farming industry, political sovereignty and even the nations health”,有人认为,恢复自给自足将促进农业、政治主权乃至国家健康。D项“有助于英国的良好发展”与文章表述一致,故选D。A项“被人口数量所阻碍”,原文中提及人口增长是带来了农业难题,并非阻碍了自给自足的发展策略,故A项错误。B项“成为政府优先考虑的事”、C项“对农业提出挑战”在文中均未提及,故均排除。
