I was privileged to hear David Suzuki speak at McGill. He was celebrating twenty years of the David Suzuki Foundation as well as launching his book: The Legacy as well as promoting the upcoming film, Force of Nature. Suzuki has been an outspoken environmentalist for decades. What I appreciate is not only does he expose the difficulties the planet faces due to man's negligence as caretakers of the Earth, but he offers solutions. We can all play a role in reversing some of the damage.
It is well worth visiting the Foundation site for pointers on the changes you can make. And then tell others.
Suzuki's CBC show, The Nature of Things has run for many years, elucidating science for all of us.
