Using on-site and archival footage to illustrate specialist and eyewitness accounts from around the world, "Scarred Lands & Wounded Lives" shows how war and preparations for war further compromise the environmental health of a planet already stressed by massive population increases, ruinous environmental practices, and unsustainable demands on natural resources. In the context of growing awareness and alarm about global climate change, it shows natural security (the protection and preservation of ecosystems) to be an essential component of any realistic approach to national security.
