plant trees that isolate CO2 biomass and couple this with a significant reduction in deforestation and greater control of insects and diseases that kill trees
Chlorofluorocarbon (CFC or CCl3F)
Chemically unreactive, odorless, nonflammable, nontoxic, and noncorrosive.
Inexpensive to manufacture, it became popular as a coolant in air conditioners and refrigerators, a propellant in aerosol spray can, a cleaner for electronic parts, a fumigant for granaries and ship cargo holds, and bubbles in plastic foam used for insulation and packaging.
Lowers the average concentration of ozone in the stratosphere.
hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs)
Substitutes for CFCs
They pose a much lower threat to ozone in the stratosphere but are much more expensive that CFCs and are potent greenhouse gases while they are in the troposphere.
This long-wavelength form of radiation causes aging of the skin, tanning, and sometimes sunburn
It penetrates deeply and may contribute to skin cancer.
This shorter-wavelength form of radiation causes sunburn, premature aging, and wrinkling
It is largely responsible for basal and sqamous cell carcinomas and plays a role in malignant melanoma.
Goal was to cut emissions of CFCs by about 35% between 1989 and 2000.
