"[A] study of climate change, examining historical and present-day causes and effects of rising global temperatures, as well as what people can do to combat climate change"--OCLC.
Explains what the ozone layer of the atmosphere is, what destroys it, how it is measured, how this depletion affects humans and life on earth, and what can be done to save it.
Discusses the dual problem of too much ozone in the troposphere creating smog and the depletion of the ozone layer in the stratosphere which shields harmful ultraviolet rays.
Discusses the nature and necessity of ozone in relation to the global environment and air pollution, and examines the greenhouse effect and ways to prevent it.
Examines the ozone layer--a thin band of gases that surrounds the Earth--discussing its importance, the threat posed by pollution, and possible solutions.
Describes the ozone layer and its important function in protecting the earth from dangerous ultraviolet rays. Also examines the threats posed to the ozone layer by chlorofluorocarbons and other pollutants and what can be done to stop further damage.
Studies the important role of atmospheric ozone in protecting the Earth, and tells how man-made chemicals are causing worrisome holes in the polar ozone layers.
