There was a design and green building conference on in Toronto for which I managed to get a free pass, although only to the exhibit hall with the vendors. But, since that was where the keynote speakers were talking, it was worth it.
Jeremy Rifkin spoke about his new book, "The empathic civilization : the race to global consciousness in a world in crisis". It was really inspiring - a very concrete plan for how the world will need to change in order to deal with global warming, and how many European countries, particularly Germany, are well on their way to working on the solutions.
I definitely want to read this book now! I'm only at 131 on the Toronto Public Library holds list; I may have to break down and buy it.
