And Mr. McLean does as well.
I would like to focus in on the definition of biodiversity. We talk a lot about biodiversity targets, but if you spend enough time on the landscape, you realize there are native species and there are introduced species. There are native species that actually cause difficulties for human beings. There are introduced species that people like; there are introduced species that people don't like. So I think the term “biodiversity targets” is much too loosely used, and nobody has really drilled down to exactly what we mean by that.
Mr. McLean and Mr. Prosper, can you comment on that?
