Though it falls short of a retirement, David Suzuki - the renowned Canadian scientist, environmentalist and activist - is preparing to step away from the public eye while he laments that he has not had a greater impact on the environmental movement.

Those were his words in a recent interview given from Australia while he was promoting the second installment of his autobiography. Suzuki said that he is looking forward to spending more time in the Canadian wilderness, carving wood and fishing and promises that this most recent book will be his last.

Dr. Suzuki is now 70 years old, and the world would be hard pressed to find a more dedicated and effective champion for the environment. His television program, The Nature of Things, is broadcast in 40 countries. He is the author more than 40 books, dozens of radio programs, has sat on countless boards and councils, holds 18 honourary degrees, and is a recipient of the Order of Canada. That his focus during this stage in his life remains firmly on the growing importance of sustainable living exemplifies his personal dedication to the environment, and the critical importance of the environmental threats we are facing today.

He will undoubtedly remain involved with numerous organizations, including the David Suzuki Foundation, in moving us towards a sustainable future. However, as he takes his first steps away from public life he will leave behind a giant's footsteps. The question is - who will have the courage to follow in them?
