Diving has been a significant part of my life for over 50 years now... even more so the last two decades. It has been a major source of wonder as I continue to try to understand the intricate ecological relationships within my local kelp forests as well as other ecosystems when I travel. It has been a source of peace (not that the topside world has been all that turbulent in my life). It is a major part of my profession as a marine biologist. It has also been a source of great "reward" (non-material) when I share that world with those who don't dive by writing my wekly newspaper columns and producing my cable TV show and DVDs.
