The industry that deals with it is becoming more efficient, the technologies are getting more effective and the pollution it causes is being controlled more tightly.
Political opposition to a cap-and-trade system has derailed efforts to limit greenhouse gas emissions in the U.S. We believe that a gradually increasing carbon charge offers a simpler, more direct, and more effective approach to pollution in general and climate change in particular.
Hybrid subsidies are more effective at reducing pollution because hybrid vehicles are typically much more cost effective.
There are theories on the table ranging from environmental lead pollution to more effective policing and crime prevention technology, or the acceptability of physical punishment and our growing sensitivity to child abuse.
Other finalists included Hugo & Hoby, an e-commerce company that brings together foresters, designers, and craftspeople to build sustainable furniture and home furnishings; and Smart Air Filters, a company that has created a more effective fan to reduce household pollution levels across China and India.
Ms. McGeorge said the best way to control the sources of pollution was through more effective regulation of watersheds, which were the areas where rainfall replenished the water supplies.
The E.P.A. says that it is more effective to control the source of pollution, to improve ventilation, and, as a supplement, to remove pollutants through proven air cleaning methods, like filters and electronic particle precipitators.
By identifying PM2.5 constituents that are more toxic, we can move toward developing source-specific air pollution regulation that may be more effective at protecting public health.
Nowak notes that although plants can certainly help reduce urban air pollution, reducing emissions is a more effective, if not necessarily an easy, first step.
New technology for more effective use of low-rank coals with significantly less pollution is highly desired.
