Chair, thank you, that's a good question.
There's no single definition of biodiversity that we've found fits all situations. In the background document we provide, we talk about that from different perspectives. Sometimes it's defined in terms of restoring natural cycles. The problem there is defining what's a natural cycle. Biodiversity is often looked at—and I think this is probably a much more useful way of looking at it—from an ecological services perspective. Here I mean the services that are being provided by an ecosystem, either to us or to others.
We do know that there's no particular definition of biodiversity. That's an important discussion and it would be a very good question to ask of the officials who will appear after me, but I don't sense that's a major constraint on a day-to-day basis for the people who are actually putting these things in place.
