Cars powered by hydrogen fuel cells and emitting only water have long been part of environmentalists’ vision for a greener transportation future. But now that electric and hybrid vehicles have caught on so big, what are the prospects for fuel cell cars moving forward?
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.
Hunger is a growing problem around the world, in both developing and developed countries. As our population continues to rise, the amount of arable land per capita is declining and climate change is either drying out or flooding many formerly productive agricultural belts, making it more and more difficult to keep up with the growing demand for food. Oceana and other groups are focusing on ocean conservation in part to help feed the world, given that wild seafood “requires no fresh water, produces little carbon dioxide, doesn’t use up any arable land and provides healthy, lean protein at a cost per pound lower than beef, chicken, lamb and pork, making it accessible to the world’s poor.”

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.
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.
