Thomas Malthus published his Essay on the Principle of Population almost 200 years
ago. Ever since then, forecasters have being warning that worldwide famine was just around
the next comer. The fast-growing population’s demand for food, they warned, would soon
exceed their supply, leading to widespread food shortages and starvation.
But in reality, the world’s total grain harvest has risen steadily over the years. Except
for relative isolated trouble spots like present-day Somalia, and occasional years of poor
harvests, the world food crisis has remained just around the corner. Most experts believe
this can continue even as if the population doubles by the mid-21st century, although feeding
10 billion people will not be easy for politics, economic and environmental reasons. Optimists
point to concrete examples of continued improvements in yield. In Africa, by instance,
improved seeds, more fertilizers and advanced growing practices have more than double
corn and wheat yields in an experiment. Elsewhere, rice experts in the Philippines are
producing a plant with few stems and more seeds. There is no guarantee that plant breeders
can continue to develop new, higher-yielding crop, but most researchers see their success
to date as reason for hope.
【M6】
选项
答案
第9行的politics→political。
解析
此处需使用形容词修饰后面的名词reasons。因此将politics改为political。
