Thomas Malthus published his Essay on the Principle of Population
almost 200 years ago. Ever since then, forecasters have being warning 【M1】 ______
that worldwide famine was just around the next comer. The fast-growing
population's demand for food, they warned, would soon exceed their 【M2】 ______
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, 【M3】 ______
and occasional years of good harvests, the world's food crisis has remained 【M4】 ______
just around the comer. Most experts believe this can continue even as ff 【M5】 ______
the population doubles by the mid-21st century, although feeding l0 billion
people will not be easy for politics, economic and environmental reasons. 【M6】 ______
Optimists point to concrete examples of continued improvements in yield.
In Africa, by instance, improved seeds, more fertilizers and advanced 【M7】 ______
growing practices have more than double com and wheat yields in an 【M8】 ______
experiment. Elsewhere, rice experts in the Philippines are producing
a plant with few stems and more seeds. There is no guarantee that plant 【M9】 ______
breeders can continue to develop new, higher-yielding crop, but most 【M10】______
researchers see their success to date as reason for hope.

After having assured their return journey,
the writer and his companion could concentrate
on collecting and film animals. Deciding to 【M1】______
enlist the help the local Indians, they made
their way to a nearby village, in which proved 【M2】______
to be a few dilapidated huts in a pleasant
valley. The Indians they found there worn 【M3】______
remnants of European clothes and had
obviously abandoned their traditional way
of life. They kept a few disease chickens 【M4】______
and skinny cattle instead of hunting for
their meat. The writer' s companion explained
that they were looking for birds and mammals,
particular armadillos, for which they would 【M5】______
pay well. Anyone who could show them inhabited
nests and holes, they have said, would be 【M6】______
well rewarded. The Indians were apathetic
and uncooperative. Noticing the absence of
biting insects, the writer asked whether
they had ever troubled by them, to which 【M7】______
the Indians replied by slowly shaking their
heads. The writer recognized that he 【M8】______
considered that having to live in such a hot,
humid atmosphere would no doubt have 【M9】______
made him lethargic too. The headman explained
the inconvenience of the villagers had, for
severe weeks previously, been contemplating 【M10】______
cutting down a particular tree and until a
decision on this matter was reached, no other
activity could possibly be considered.
