Слайд 6
Acid rain - rain carrying acid pollutants from
traffic fumes, industrial output, central heating and air conditioning
.
Слайд 7
Ozone layer - the protective layer of ozone
gas which blocks out the sun’s harmful ultraviolet rays.
CFC’s (chlorofluorocarbons), which are found in aerosol sprays and refrigiration units, attack and destroy the ozone layer
Слайд 8
