Exxon Valdez. According to Pamela

¶ … Exxon Valdez.

According to Pamela Miller of the Alaska Wilderness League, while Prince William Sound may appear clean to the naked eye, "oil continues to contaminate beaches, national parks, and designated wilderness. In fact, the Office of Technology Assessment estimated beach cleanup and oil skinning only recovered 3-4% of the Exxon Valdez oil and studies by government scientists estimated that only 14% of the oil was removed during cleanup operations" (Miller 1999). A drop of oil can kill a bird's egg and the impact of the Valdez calamity has taught scientists that oil pollution is 100 times more toxic to fish than believed before the accident on the Sound.

List three subjective facts about twins

"Expecting parents often become indifferent" when asked if twins run in the family "after being asked it the first 40-50 times;" if twins do 'run in the family,' family members should help out, in case they themselves need the added assistance later on; families uncertain about their ability to handle twins should think twice about planning a family if twins run in the family, if they are contemplating fertility treatments, or if the mother is over age 35.
