[单项选择]THE ivory-billed woodpecker is not large, as birds go: It is about the size of a crow, but flashier, its claim to fame is that, though it had been thought extinct since 1944, a lone kayaker spotted it about two years ago, flying around among the cypress trees in the Cache River National Wildlife Refuge. And that sighting may prove the death-blow to a $319m irrigation project in the Arkansas corner of the Delta.
The Grand Prairie Area Demonstration Project seemed, at first, a fine idea. The Grand Prairie is the fourth-largest rice-bowl in the world, with 363 000 acres under paddies. But it is running out of water, with farmers driving wells deeper and deeper into the underlying aquifer. The new project, dreamed up around a decade ago, would tap excess water from the White river when it floods and pumps it, at the rate of about one billion gallons a day, to storage tanks on around 1000 rice farms.
Unfortunately, it would also divert water from the region’s huge, swampy wildlife
A. Blanche Lincoln had intensive intention to protect natural environment.
B. Mr. Bumpers extended his influence by his constant endeavors.
C. Maybe some years ago, Mr. Bumpers kept hostile posture to this kind of irrigation project.
D. Many of refuges were constructed by Mr. Bumpers himself.
