I think my colleagues here have alluded to what hasn't worked in the past, or what has worked up to a point, and that is having each side of the equation—whether it be the economic side versus the conservation or environmental side—drawing hard and fast lines around “thou shalt not trespass” over my line here. What you end up with, then, is no way of actually going beyond where we are today in terms of conservation.
I can give an example. For instance, mining companies are quite worried about seeing expanded protected areas that would have subsurface rights taken away, because you never know what you're going to find there some day.
Are there some other mechanisms? That is why I put forward the biodiversity credits. Are there some other ways in which we can look at resolving these tensions? Really, they shouldn't exist. If you actually talk to the folks in the mining companies, in many ways they're just as keen about seeing areas conserved as we are.
