A special issue of the Yale's Journal of Industrial Ecology focuses on the results of innovative research identifying the most significant sources of pollution and impact to the environment. Air and automobile transportation; meat, chicken, fish and dairy production; and household appliances and energy usage in homes top the list accounting for up to 80 percent of the impact on the environment. These findings are important because they specifically identify consumer, industrial and commercial activities that comprise the bulk of most of the damage done to the environment. The research may help identify ways to protect the environment as well as provide data to develop programs that can be implemented to counter or prevent environmental impact.
