All of us have a common home, which is the Earth. We would not be able to survive if we lose the Earth. However, due to human activities, the environment on Earth is being destroyed and many resources are depleted. This book vividly introduces some knowledge of energy and environment that is closely related to human health via lively and humorous comic stories. Through these stories, children can understand the environment that they rely on to survive, learn to avoid potential environmental pollution that may occur in daily life, and learn to acquire scientific knowledge of environmental protection. Let us work together to protect our Mother Earth.
