Some public health experts are concerned that a changing global climate, along with increases in carbon dioxide emissions, might be contributing to a sudden rise in the number of asthma cases. The Great Lakes Radio Consortium’s Lester Graham reports.
Worldwide, the level of carbon dioxide released into the atmosphere has risen. So scientists have been studying what might happen to plants if the C-O-two level continues to rise. One study indicates the increase in C-O-two levels makes conditions more favorable for weedy species… such as ragweed, which aggravates asthma. Paul Epstein is with the Harvard Medical School and has been working with the study.
“The ragweed pollen counts go up so that doubling of asthma in the last several decades may be partially accountable just by the rise in CO-2 as well as, perhaps, prolongation of seasons and the early arrival of spring and the late arrival of fall.”
Epstein says it appears the air pollution that is believed to be causing global climate change and triggers asthma could be compounding the problem by indirectly contributing to the increase in pollen allergens. For the Great Lakes Radio Consortium, I’m Lester Graham.
