We know that smog and ground-level ozone exceed levels considered safe by government standards in some places across the country.

Mr. Speaker, the second petition is with regard the atmospheric ozone layer, which is critical to life on Earth, through its regulation of ultraviolet radiation from the sun.

The main substances attributed to the depletion of atmospheric ozone are halogenated hydrocarbons, chemicals invented in 1928 as refrigerants.

32. Stresses that black carbon remains as prevalent a cause of glacial retreat as carbon dioxide; recalls, in particular, that black carbon and ozone in the lower atmosphere are harmful air pollutants which damage health, reduce life expectancy and exacerbate the melting of snow and ice around the world, including in the Arctic, the Himalayas and other glaciated and snow-covered regions; highlights the fact that ozone is also the most important air pollutant responsible for reducing crop yields, and thus affects food security; notes that methane is an important precursor to ozone formation and that reductions of methane emissions also ...[+++] reduce the formation of ozone;
