For some people, working with dangerous chemicals and heavy metals is just part of the job. The right safety gear and procedures can keep workers healthy, but in the case of newer, more recently-created chemicals, the health risks are often unclear.


Climate Change & Nutrition

Climate change puts at risk the food supplies of people in developing and developed nations alike. Floods, droughts, more intense hurricanes, heatwaves and wildfires can drive down crop yields, destroy livestock, and interfere with the transport of food. Rising carbon dioxide levels from human activity can make staple crops like rice and wheat less nutritious.

Seafood, Mercury, & Health

Harvard researchers have traced the major sources of methylmercury, a poisonous form of metal, in the U.S. diet. Although most of that exposure comes from eating seafood, the geographic origins of the mercury hasn’t been well understood until now.

Q&A: In Madagascar, climate change means public health peril
