Arctic National Wildlife Refuge:
Should we drill?
Arctic National Wildlife Arctic National Wildlife RefugeRefuge
ANWRANWRFor
In 2006, the U.S. House of Representatives passed for the tenth time a motion that would allow oil drilling in the Arctic National Wildlife Refuge (ANWR)
Growing foreign dependence on oil threatens American security and that drilling in ANWR would help reduce that dependence
Drilling and extraction of oil would not meaningfully harm the environment
Drilling would promote the economy and create new jobs
Against
U.S. dependence on foreign oil is inevitable and that drilling in ANWR would not significantly reduce dependence
It would damage a sensitive ecology and undermining the principle of national environmental protection
Drilling is supported by many politicians, and critics charge that they are doing favors for their friends in “Big Oil”
