“Four- and five-year-olds living along the city’s greenest streets were less likely to have asthma than young children living in sparsely planted neighborhoods, Dr. Gina S. Lovasi and colleagues from Columbia University found.
“We think that trees might have a beneficial effect on air quality — affecting air quality right at the street level,” Lovasi told Reuters Health. While the effects were independent of poverty and pollution, the researcher added, its possible street trees may simply be a stand-in for a healthful environment. “We’re not confident that it’s the trees themselves that are what’s driving this.”
Asthma rates have risen sharply in the US since 1980, and inner cities have been hit particularly hard, Lovasi and her colleagues note in their report. Trees could cut asthma risk by cleaning the air and encouraging kids to play outdoors, they add; but the pollen they release could also contribute to asthma attacks. To investigate, the researchers compared a census of New York City’s half-million street trees from 1995 to statistics on asthma prevalence and hospitalisation rates for 1999.â€â€
