The beauty and variety of Sydney’s landscape and ecosystems are brought into stunning focus in Sydney's Natural World by John Martyn of STEP Inc. Publisher STEP Inc. is a substantial Sydney-based environment group that believes that urban environmentalism is much more than fighting against destruction and degradation. STEP contends that it is essential to educate and inspire the community to appreciate what we have if the battle against the unthinking and the destroyers is to be won. Sydney's Natural World is an important step in that education and inspiration program; it shows beautifully just what STEP is fighting to conserve and what will be lost if we fail to be vigilant.
