First it was pets, then fish. Now it’s poultry and pigs. The【C1】________of animals allowed to feed on insects is growing. A new EU law【C2】________the use of insect protein in poultry and pig feed came into【C3】________earlier this month, which is a significant【C4】________for an industry keen to【C5】________ its way into the animal-feed business.
【C6】________a ban on processed animal protein was imposed in 2001 in the【C7】________of the "mad cow" crisis, soy and fishmeal have become the bedrock of animal feed in Europe. But their production needs lots of space and can be【C8】________to the environment, so feed manufacturers are looking for【C9】________.
Insects are just the ticket. They are reared in vertical farms that require little land or water, and they can be fed on agricultural by-products or food waste【C10】________rotting fruit and vegetables. They’re also a natural【C11】________. Most wild fish, birds and pigs eat insects.
The one thing going【C12】________them is price: insect protein is two to three times more expensive than fishmeal, and many times pricier than soy. Scaling up production may help close the gap. Rabobank, a Dutch lender,【C13】________that global insect production will reach 500,000 tonnes a year by 2030, and that prices will tumble.
Insect companies have【C14】________hard on their pitch. Research suggests insects may be more than mere feed,【C15】________growth rates and immune systems as well as filling stomachs. They also offer the【C16】________of a green, local protein.
Poultry and pig feed are by far the largest animal-feed markets, but they’re more【C17】________ than food for pets or fish. For that reason, says Antoine Hubert, CEO of Ynsect, a mealworm firm, insect protein will probably be used only in premium meat at first.
This year the European Food Safety Agency has ruled that three【C18】________of insects (yellow mealworm, locusts and house crickets) are【C19】________for humans to eat as well.【C20】________. however, people seem less keen on the idea than chickens and pigs.
【C19】
选项
A、beneficial
B、necessary
C、safe
D、indispensable
答案
C
解析
空格所在部分为three species of insects (yellow mealworm, locusts and house crickets) are________for humans to eat as well (黄粉虫、蝗虫和蟋蟀三种昆虫也可以供人类________食用)。既然欧洲食品安全局裁定这三种昆虫可以供人食用,那说明就是安全的,再者,前文一直提及一些动物可以食用昆虫,这里as well表明人类也可以安全食用,因此答案为C项safe。A项beneficial意为“有益的”,后应接to sb./sth. ,故排除。B项necessary意为“必要的”,D项indispensable意为“不可或缺的”,原文只是说这三类昆虫人类吃了没有危险。但并非就是必需的或不可或缺的,故排除。
