我们将来会吃面包虫么?
素材正文：
A pound of chicken will set you back a couple bucks. 
Ground beef, maybe three to four dollars a pound. 
But a pound ofprotein-rich dried mealworms could cost twice as much.
"The price per pound of mealworms is still relatively expensive." 
Juan A. Morales-Ramos is a research entomologist with the USDA in Stoneville, Mississippi. 
But he says that cost might be coming down.
For eight years, he and his team have selectively bred mealworms, which are the larvae of a type of darkling beetle. 
Their goal was to breed larger and larger worms - and they succeeded in nearly doubling the size of the larvae. 
单词解析:

But doubling up came with an evolutionary tradeoff: larger larvae had fewer eggs, and their offspring weren't as hardy as the ancestralstrain.
Still, generations are shorter in the worm world—meaning it's faster to experiment—and sequencing the genes of the selected strains might reveal new traits to breed for.
"We may be able to produce a superline of mealworms that grow faster and larger and probably produce more eggs, hopefully."
 The findings are in The Journal of Insect Science.
The eventual goal is to bring mealworms beyond fishing bait. 
If the cost comes down, they'd be an economical protein source for farmed fish and chicken feeds. 
Andone recent study rated them as significantly healthier than beef or chicken—for a human diet. 
Other cultures are leading the way.
"There are many cultures not just in Mexico but in Asia and Africa that regularly consume different types of insects. 
They sell them in the market.
 In Mexico there are restaurants that specialize in serving insects. 
And I'm not talking just regular restaurants, these are like five star restaurants doing that."
Of course, here in the US we also eat insects.
But in the near future we might do it on purpose.
单词解析:
1.Tradeoff  n.权衡,折中
