Future of environmental pollution.

In recent years, the concept of pollution prevention has overtaken end-of-pipe controls as the paradigm of choice for effecting environmental protection. Through cooperative mechanisms, significant progress is being made to reduce or eliminate upstream processes and practices that can lead to downstream pollution. These efforts, coupled with productive interactions with the public, are making an impact. The Science Advisory Board released a report in January that described the "next wave" of pollution prevention. Specifically, the report described approaches for anticipating environmental problems of tomorrow so that preventive actions can be taken today. The potential of air pollution problems figures prominently in the Board's vision of the future.
