[简答题]It is just one example of the growing concern over the increasing power consumption and environmental impact of computers. A study found that the power consumption of data centers doubled between 2000 and 2005, and now accounts for 1.2% of American electricity consumption, though other estimates put the figure at 4%. Companies now spend as much as 10% of their technology budgets on energy, says Rakesh Kumar of Gartner, a consultancy.
Power consumption has increased because of the rise of the internet, of course, but also because of way in which computers have historically been designed: to maximize performance at all costs. Between 1996 and 2006, the number of servers in use went from 6 million to 28 million and the average power consumption of each server grew from 150 watts to 400 watts. But things are now starting to change and the computer industry has been seized with enthusiasm for "green computing".

Organic food has no nutritional or health benefits over ordinary food, according to a major study.
Researchers from the London School of Hygiene & Tropical Medicine said consumers were paying higher prices for organic food because of its imagined health benefits, creating a global organic market worth an estimated $48 billion in 2007.
A systematic review of 162 scientific papers published in the scientific literature over the last 50 years, however, found there was no significant difference.
"A small number of differences in nutrient content were found to exist between organically and conventionally(通常)produced foodstuffs, but these have nothing to do with public health, " said Alan Dangour, one of the report’s authors.
"Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority. "

The End of Food Has a tech entrepreneur come up with a product to replace our meals
A. In December of 2012, three young men were living in a claustrophobic (患幽闭恐惧症的) apartment in San Francisco’s Tenderloin district, working on a technology startup. They had received a hundred and seventy thousand dollars from the incubator Y Combinator, but their project—a plan to make inexpensive cell-phone towers—had failed. Down to their last seventy thousand dollars, they resolved to keep trying out new software ideas until they ran out of money. But how to make the funds last Rent was a sunk cost.

For as long as most people can remember, food has been getting
cheaper and farming has been in decline. In 1974--2005 food prices on world
markets fell by three-quarters in real terms. Food today is so cheap that the
West is battling gluttony even as it scrapes piles of half-eaten leftovers into
the bin.
66. __________.
The Economist’s food-price index is
higher today than at any time since it was created in 1845. Even in real terms,
prices have jumped by 75% since 2005. No doubt farmers will meet higher prices
with investment and more production, but dearer food is likely to persist for

diet that accompany the growing wealth of emerging economies--the Chinese
consumer who ate 20kg of meat in 1985 will scoff over 50kg of the stuff this
year. That in turn pushes up demand for grain: It takes 8kg of grain to produce
one of beef.
67. __________.
Dearer food
