Global dimming is a fact of life now. The particles form aerosol cans are the major factor creating the smog that reduces the amount of sunlight reaching the earth’s surface. The particles from the cans adds to the soup in our air that is attributed between 800 and 1,700 deaths in Toronto a year. On top of this are the millions of dollars lost to our economy due to respratory sickness and demands on our medical system. The dimming is also blamed for reductions in water evaporating which leads to less rain and therefore the droughts we have experienced which in turn leads to reduce crop yields.. Some statistics suggest that rice production in China is down 30% and 10% in India. All levels of Government have to act now to improve the quality of our air.
