Many Asian cultures have included frog legs in their diets for centuries or at least until they have run out of frogs. But the most famous frogeaters, and the people who inspired frogeating in Europe and the United States are the French. By 1977 the French government, so concerned about the scarcity of its native frog, banned mercial hunting of its own amphibians. So the French turned to India and Bangladesh for frogs.As happened in France, American frogleg fanciers and restaurants also turned increasingly to frozen imports. According to figures collected from government agencies, the United States imported more than million pounds of frozen frog meat each year between 1981 and 1984.So many frozen frog legs were exported from India to Europe and the United States. One of the attractions of Indian frogs, apart from the fact that they have bigger legs than French frogs, was the price. In London, a pound of frozen frog’s legs from India cost about ￡, pared with ￡ for the French variety.Indian scientists have described as “disastrous” the rate at which frogs are disappearing from the rice fields and wetlands, where they protect crops by devouring damaging insects.Since the India and Bangladesh frogexport bans, Indonesia has bee the major exporter of frog legs to the United States and Europe. But no matter what country the legs e from, one thing is usually constant: The legs once belonged to frogs are taken from the wild, not from farms. Frogs are nearly impossible to farm economically in the countries where frogs are mercially harvested from the wild.Exercise A:1.
