This is a worldwide survey of key environmental themes, reflecting today's concerns. This book explains how without air there would be no life on our planet. Air pollution affects the climate, the evolution of species and the food we eat. Everyday we are poisoning the air we breathe with exhaust gases, industrial pollution and other effluent. The seven richest of over 200 countries in the world create one third of global warming. If action is taken now the ozone layer may repair by 2050. Dr Baines explains how environments are affected by human interference and how difficult it is to counter those who materially benefit from environmental exploitation. He describes how companies and individuals are taking action to improve the situation.

John Baines is a consultant and writer on geographical and environmental issues. He has an MBE for services to environmental education, and has written many books and articles for both children and adults.
