This atlas presents an in-depth overview of the issue of endangered species. A series of maps reveals the extent of such global problems as natural disasters, pollution and population growth. This is followed by detailed surveys of the seven key biological areas of the world, which explain the problems they face, and identify those animals and plants at risk. The final section describes what steps are being taken at international and national levels to preserve and conserve our planet's natural heritage, charting the successes and failures of the conservation movement, and setting out what the individual can do to help.
