This increases the productivity of successful wells, allowing for more petroleum and natural gas to be extracted from the ground. In fact, 3-D seismic can increase the recovery rates of productive wells to 40-50 percent, as opposed to 25-30 percent with traditional 2-D exploration techniques.
Even though America's food supply is the safest in the world, millions of people are affected by foodborne illnesses. According to the Centers for Disease Control (CDC), foodborne illnesses cause about 76 million cases of illnesses, 325,000 hospitalizations, and 5,000 deaths in the United States each year.
In the Unites States, it affects around 72,000 people, most of whose ancestors come from Africa. The disease occurs in about 1 in every 500 African-American births and 1 in every 1000 to 1400 Hispanic-American births. About 2 million Americans, or 1 in 12 African Americans, carry the sickle cell allele.
