A PRIMER ON AIR POLLUTION

Steve Kannon in the Woolwich Observer has under Editor's Notes an article titled "Enjoying the fresh air while it lasts". I would describe it as an excellent primer on the causes and makeup of air pollution and smog in North America. The extent of health effects, including premature death, are staggering. Also of interest is the fact that as our manufacturing economy has imploded our air is improving. Heavy industry, coal fired power plants and automobiles are the main culprits and the first two are in decline. The decrease in manufacturing has also freed up electricity requirements dramatically which is another good thing for the environment. On a daily small basis Steve advises us that believe it or not, barbecues, campfires and gas mowers are all actually relevant to the problem. Hunh!
