I would answer that question at two levels. First, coming back to the point I made just a moment ago, there will be some form of environmental impact from almost any industrial activity. Our job is to try to mitigate those impacts, and as I said earlier, as a matter of principle, to try to land with regulators and governments and other stakeholders on the appropriate balance between environmental protection and economic growth.
I would certainly not suggest that any sort of economic activity or industrial activity, should it have an environmental impact, be stopped. Our job is to try to mitigate those impacts and find the right balance. As I said in my remarks, I think it's important to think about conservation in that broader context. We try to mitigate or reduce impacts in the first instance. You've heard many examples of that, as Murray will comment in a moment.
We try to make sure we restore and reclaim land that is impacted. In some cases there will be high-value areas that legitimately should be protected, and where land activity in one form or another should be minimized and in some cases precluded. I think it's important to look at it in that broader context and to think about all of this under a broad principle, which is that we need to find the appropriate balance between economic activity and environmental performance, and also think about it in a temporal context whereby you can develop and impact the land and still come back to conservation and other objectives over a period of time.
Murray may want to add to that.
