Blue Sky Defense

The environmental protection volume of the "e;Green Aquarius"e; series of popular science books continues the style of the "e;Blue Key"e; ocean volume that has been published by our agency. It uses the two typical images of "e;little dragon man"e; and "e;silk fish"e;, which are unique to the series, to explain the definitions and concepts that are relatively boring and difficult to understand, and to deduce natural phenomena and technological products. This book begins with the familiar "e;smog"e;, analyzes its causes and effects, and proposes feasible countermeasures. Next, it introduces the common pollution sources of air pollution, finds out the "e;culprit"e; of air pollution, makes readers realize the urgency of preventing and controlling air pollution, and guides readers to protect the environment and improve their awareness of environmental protection.
