The way in which humans are attempting to live is unsustainable. Many of our cultural norms that are considered good, righteous and healthy are not. We have become a dangerous species, altering our physical and chemical biosphere and killing far too much life on the planet. If we learn from our mistakes and change, we will survive quite nicely. However, if we continue what we are doing there will be serious consequences. Written in a conversational tone that anyone can understand, this is a unique environmental science lesson for all. Including discussions of the scientific principles at work as well as the ethical and moral issues at stake, this informal but informative volume covers topics from global warming and climate change to species extinction, overpopulation, disease and energy - and how our political, social and economic culture affects them all. There are ramifications to being a modern human that make us and our behaviors unnatural, at odds with the earth - paradoxically, the earth that we are totally dependant on. This book will suggest what needs to change if we want to survive on our only planet.
