In what way does pheromone work on the same species of plant or animal? [br]
We’ve now had a way of working on insects to change their behavior with how to stop locusts swarming, and a possible way of changing crops to help them survive a drought. Now here’s an ingenious piece of research that tries to do both at the same time. To control insect activity and help the crop grows through one treatment. It’s all down to pheromones, the chemical signals that allow members of the same species of plant or animal to communicate. They’re as powerful as hormones, which travel in the blood, but unlike hormones they travel through the air. And it’s the 50th birthday of their discovery this year.
The Worldwatch Institute said in 2011 far too many people were living with less than they needed. It says, for example, nearly one billion people were hungry and just as many were illiterate. Worldwatch Institute’s Danielle Nierenberg said while a billion people went to bed hungry each night, it wasn’t because of a lack of available food. The director of the Nourishing the Planet Project said besides poverty and a lack of access to food, much food is simply lost. Worldwatch estimates 1. 3 billion tons of food is wasted each year.
选项
A、The booming world population.
B、The low productivity.
C、The astonishing waste of food.
答案
C
解析
文中提到besides poverty and a lack of access to food,much food is simply lost,下文中也有说到1.3 billion tons of food is wasted each year。所以答案选C,即过度的粮食浪费。
