I want to preface my answer by saying that I'm not a scientist, but my personal opinion would be that you have to be more flexible in urban areas. I think we need green spaces as well for a lot of the other reasons we talked about.
We do need strict conservation areas in urban settings as well. As I was mentioning in my remarks, they can be very expensive to manage properly—not that we shouldn't try.
I think we have to get into a lot more mixed-use areas within urban areas to protect what remaining wilderness we have or what green spaces we have in these areas.
