Editor's note: The profile was written by Friends of the Earth, the organization Kendra works for. Next up is Staff Scientist Kendra Klein who supports our agroecology work. She has over 14 years of experience as a writer, researcher and environmental advocate. Her areas of expertise are environmental sustainability, environmental health and food and agriculture. She talks with us today about why she joined Friends of the Earth and the role of women in the environmental movement.

Since the crisis in Flint hit the national headlines, the problem of lead exposure from drinking water has come under greater scrutiny. And for good reason. Seven to ten million American homes have water delivered through service lines made of lead pipe – the primary source of lead in drinking water.

For one week, 92 preschool-aged children in Oregon sported colorful silicone wristbands provided by researchers from Oregon State University. The children’s parents then returned the bands, which the researchers analyzed to determine whether the youngsters had been exposed to flame retardants. The scientists were surprised to find that the kids were exposed to many polybrominated diphenyl ethers (PBDEs), chemicals that are no longer produced in the U.S., as well as to organophosphate flame retardants, which are widely used as substitutes for PBDEs.

Like rainwater harvesters and solar panels, biodigesters generate power by reinvesting natural resources back into their own ecosystems. Because of their potential to reduce both waste and operating costs, it seems like every family farm should have one on hand. Fellow Alexander Eaton's company, Sistema Biobolsa, is working to create a base of users that leads to a tipping point.

Did you know every time you step on your car’s brake – whether at a stoplight, an intersection or while parking– small amounts of copper debris are released onto the streets and into the air, eventually making it into California’s waterways? Considering the millions of drivers in the state, and the number of times we all hit our brakes, the cumulative impact of copper debris takes a toll on California’s environment.

Fellow Rachel Morello-Frosch believes, despite the uncertainties, doctors and other clinicians can offer women very useful advice. For example, diets rich in organic foods reduce exposures to pesticides, as measured by urinary levels of their metabolites. And people can choose not to buy body lotions known to contain phthalates or furniture with foam cushions steeped in flame-retardants. Indeed, advising patients on the best ways to reduce potentially toxic chemical exposures is an essential component of public health prevention.

While blood lead levels were declining, scientific evidence was mounting to show there is no safe level of exposure to lead in infants and young children. Studies showed that adverse neurological effects were happening at lower and lower levels of lead exposure. In 2012, the Centers for Disease Control and Prevention reduced the level of lead in blood used to identify those with elevated exposure to 5 µg/dL. Today, approximately 500,000 children have levels at or above 5 µg/dL.

A yellow torpedo prowls the Monterey Canyon, gliding over fields of eerie red and white clams nearly 3,000 meters below the surface. The submarine then slips down deep to survey the little-known creatures sprawled beneath it. Here in the darkness, otherworldly life abounds in the cold, crushing depths of the Pacific.
