Car pollution can damage brain?

I copy some parts of the article for you, to give you a thorough explanation. " Scientist recreated the air born pollutants that come from the burning of fossil fuels and the weathering of car parts pavement,and exposed mice to the harsh air for 15 hours per week over 10 weeks. The tiny particles were "roughly one-thousandth the width of human hair, and too small for car filtration systems to trap," but exerted massive damage on the brain of the expose mice, said the study. "You can't see them but they are inhaled and have an affect on brain neurons that raises the possibility of long-term brain health consequences of free way air," said senior author Calib Finch of the University of Southern California. Scientist found that the exposure resulted in "significant damage," to neurons involved in learning and memory, and they detected, "signs of inflammation association with premature aging and Alzheimer's disease." I hope this will answer your questions.

I didn't know it either, until I read. Pollution is of the major causes of health problems, we can't eliminate however we can lessen by doing something, we just need to be aware on how and what to do and everyone should cooperate, pollution is always with us until the moment we leave in this world.
