Climate Change and Food’s Nutritional Value
It’s difficult to say whether or not the climate change we are now experiencing is negatively impacting the nutritional quality of our food, but researchers warn that it may be only a matter of time.

Ocean Sprawl
Dear EarthTalk: I recently heard the term “ocean sprawl,” which was a new one on me. We all know “sprawl” as it manifests itself above sea level. But in the oceans? Can you enlighten?

Concerns about Parabens in Health, Beauty and Personal Care Products
Parabens are a common preservative in many health and beauty products, but is our constant exposure to them too much? Researchers worry that these endocrine disruptors are leading to more cancers and other health problems.
Improving School Lunches
Americans have done a great job making sure that our kids have something to eat at school regardless of socioeconomic status, with the National School Lunch Program providing low-cost or free lunches to upwards of 31 million students at 92 percent of U.S. public and private schools. But that doesn’t mean the food has been especially nutritious, and public health experts say it’s no wonder our kids are more obese than ever when we feed them trans fats, salts and sodas for lunch. Kids get half their daily calories at school, so what’s for lunch there has a big impact on health and lasting eating habits.
Chemicals and Obesity
The rise in obesity and related health problems like diabetes is usually attributed to an abundance of high-calorie food coupled with the trend toward a more sedentary lifestyle, but there is more to the story. A growing number of researchers believe that certain chemicals collectively known as “obesogens” may be a contributing factor to the growing obesity epidemic. Exposure to these chemicals has been shown to interfere with the way we metabolize fat, leading to obesity despite otherwise normal diet and exercise.
Synthetic Biology
Dear EarthTalk: Should those of us who care about our health and the planet be concerned about the new trend in genetic engineering called synthetic biology?
