Smokey seas. I’m Bob Hirshon and this is Science Update.
A study from the National Oceanic and Atmospheric Administration found that
cargo, tanker and cruise ships emit about two million pounds of sooty particulate pollution each year. That’s about half of what all the nation’s cars produce, and it’s all concentrated within 250 miles of shore. The study concludes that the pollutants are a significant health concern for residents of coastal cities—especially in cities that also have high levels of car, truck and power plant pollution.
In other environmental news, a new European Union project aims to develop new technologies for tapping heat from deep in the earth. They recently identified reservoirs in a region of Italy capable of producing more energy than a thousand wind turbines. I’m Bob Hirshon for AAAS, the Science Society.
