Dalgleish, Sharon. Cleaning the Air. 2002. 32p. ISBN 978-0-7910-7019-0. Available at 363.739 DAL on the library shelves.
This short book presents information about the air cycle and the impact human activities have on the quality of the air we breathe. As no new air is created, how we live directly affects what we breathe in. Air and its characteristics are presented, followed by how it is cleaned by the process of photosynthesis. The carbon cycle is explored along with the connection between electricity generation and pollution. Finally, the methane released by cattle and the acid that falls from the sky are mentioned.
