Clean Air Technologies
When it comes to air pollution, there is good news, there is bad news, and there is reality. The good news is that during the past three decades, environmental measures and new technologies have helped reduce air pollution dramatically, by almost 50 percent. The bad news is that worldwide, the atmosphere over our cities is still smoggy, more areas are urbanizing, and the number of cars on the road is increasing. The reality is that engineers have developed dozens of creative methods to curb pollution, and although there is no magic bullet, some combination of these approaches may hold the answer. In this slide show, get to know a handful of tools for reducing and preventing air pollution.
