"The most curious result obtained appears to me to be that relating to the effect of a highly ozonized atmosphere upon the roots of plants." – M. Carey Lea, 1864."
"To the philosopher, the physician, the meteorologist and the chemist, there is perhaps no subject more attractive than that of ozone." - C.B Fox, 1873
► Surface O3 will have an increasingly detrimental impact on future crop yields. ► Yields of wheat, soybean, and maize could be reduced by up to 26% globally in 2030. ► Global losses up to 17% are possible even in an optimistic scenario of future O3. ► Agricultural losses worldwide may be worth $17–35 billion annually by 2030. ~ Princeton University, Global Crop Yield Reductions Due To Surface Ozone, 2010
"Natural ecosystems have been altered in various ways by nitrogen, sulfur, and mercury deposited in rain, snow, or as gases and particles in the atmosphere. Through decades of scientific research, scientists have documented how local, regional, and global sources of air pollution can produce profound changes in ecosystems. These changes include acidification of soils and surface waters, harmful algal blooms and low oxygen conditions in estuaries, reduced diversity of native plants, high levels of mercury in fish and other wildlife, and decreased tolerance to other stresses, such as pests, disease, and climate change."
