interesting study shows the affects of pollution:
"Scientists have discovered that exposure to microscopic pollutants from car exhausts and burning fossil fuels can lead to weight gain in youngsters brought up in cities.
They also found that the pollutants cause increased insulin resistance, which can lead to the development of Type 2 diabetes.
The study suggests that children who grow up in cities with high levels of pollution could be prone to health problems later in life.
The scientists based their results on tests on mice and the pollution levels they were exposed to matched the levels found in urban areas."
