"We should feel an urgency about our environment and what's been done to it by human action and inaction. I wouldn't say there's a resurgence - I think it's been with us all along, and especially since the 1960s and 1970s, but it is true that there's almost a subsection of the bookstore devoted to it now. Personally, I've been addressing these issues in my long and short fiction since the late 1980s - basically since the beginning of my career."
