Important Questions on Some Common Diseases
The release of crude petroleum oil into the environment, especially marine areas, due to human activities is known as oil spill. Oil penetrates into the fur of animals and plumage of birds, thus reducing their insulating ability and making them less buoyant in water. Oil also impairs a bird’s flying ability. This oil on entering the body of animals affects the functioning of their digestive tract, liver and kidney. This leads to a metabolic imbalance in them. There are some aerobic and anaerobic bacteria which are capable of consuming oil and cleaning marine areas such as general aerobic bacteria (GAB), sulphate-reducing bacteria(SRB) and acid-producing bacteria.
