First, do you know what ANWR is? ANWR = Arctic National Wildlife Refuge. Now, a comparison (ANWR in orange, drill area in yellow):

And some perspective.

The parts of ANWR they show you in pictures.

The real ANWR coastal plain where drilling is proposed.

But what about the effect on the wildlife?

Read the real story in words and pictures here.

The USGS estimates that there is a 95 percent probability (a 19 in 20 chance) that at least 5.7 billion barrels of oil may be technically recoverable from the ANWR Coastal Plain of the Alaska North Slope. The original oil in place corresponding to this recovery is at least 15.6 billion barrels. EIA scheduled daily production rates for postulated yearly development rates of 250 and 400 million barrels per year. The production rate peaks at 650,000 barrels per day for the development of 250 million barrels per year and at 800,000 barrels per day for the 400 million barrels per year development case. Geologists say there could be less or much more.
