Today our planet earth has a little over 7 billion people. Every one of us has basic needs such as food, housing, health care, and energy to power our economies. As we go through life, we consume natural resources, generate waste and in the process we do negatively impact the environment. There is a need for each one us to understand how our actions impact the environment. We must also understand what we need to do in order to minimize our impact on the environment and to live on this planet sustainably. This book introduces environmental science in a way that is easy to understand even if the reader has no prior knowledge of the subject area. The material is presented in a way that stimulates the reader to pick interest in ethical and sustainable living. This is particularly important for students who are not environmental science majors.
