Testimony for Earth is founded on the six core principles and five action principles of the Manifesto for Earth created by two talented Canadian scientists, Dr. Ted Mosquin and Stan Rowe, and published in the January-March 2004 issue of Biodiversity - Journal of Life on Earth. The value of the Manifesto principles is that they offer concepts that can serve as a guide to what we should and should not do to help save the planet and ourselves. Testimony for Earth expands upon, illustrates, and gives examples that encourage a more sustainable worldview than is currently held. Political, economic, and religious principles rest on the erroneous assumption that human beings are the only creatures of importance in the universe. Testimony for Earth compels us to realize that all living organisms are Earth beings - earthlings - born and sustained at all stages of life by the health and integrity of Planet Earth. In a philosophical sense it suggests that we can only justify our own being by realizing that we are but parts of the wholeness of our planet. This book makes us look around and realize that all living beings hold their lives by the same thin threads by which we hold our own.
