This summer, Ontario’s “Green Energy and Economy Act” (Bill 150) was approved by the Legislative Assembly of Ontario. Since that time, it has received international recognition as a model policy framework in sustainable energy policy. Declaring a bill as law, however, is only the first of many steps to transforming a policy proposal into legislation. To learn about one of the barriers – configuring the proposal into the existing legal framework – Environmental Law correspondent Naomi Jehlicka speaks with lawyer Elliot Smith, an Associate with Osler, Hoskin, and Harcourt LLP, which is involved with implementing the Act.

We break from our usual format to present a giant of the global environmental movement, British scientist James Lovelock. Lovelock is well known for his scientific work detecting CFC’s and linking these gasses to processes contributing to the ozone hole. This work set in motion global agreements to restrict ozone-depleting gasses and won his group the 1995 Nobel Prize in Chemistry. Today, however, Lovelock is one of the few Nobel prize winners who can be described as better known for a different idea – not one that won a Nobel prize. In Lovelock’s case, that idea is “the Gaia Hypothesis”. Conceiving of the entire planet as a enormous superorganism, Lovelock gave birth to a new way of thinking about life on earth. In today’s lecture delivered at the Glenn Gould Studios in Toronto, Lovelock presents Gaia’s struggle for survival in a lecture based on his book, “The Vanishing Face of Gaia: A Final Warning”. Thanks to Danny Leskiw for recording this lecture.
