EHN aggregates links to articles in the world press about environmental health, with daily updates. Topics carried include a broad array of issues in environmental health, including: chemical contamination, water quantity and quality, air pollution, sewage, Mad Cow disease, and genetic engineering, etc. as well as climate change and biodiversity stories with a health dimension. We make a special effort to find media coverage of new scientific findings related to these issues. We do not cover pure energy, 'critter stories,' or animal rights. Anything covered should have, at least implicitly, a link to human or ecosystem health.
