Well, that's a really good example, because risk assessment tries to control the damage but not prevent the damage, and that's the distinction. Risk assessments are about controlling as opposed to preventing.
The question is what alternative technologies there are in place. What's not required as part of the risk assessment process is to look at alternative, safer ways of drawing in that water. It's not a requirement under the risk assessment method.
That would be under a new method, and one of the recommendations I have is to take what's called a precautionary approach to managing potential projects. The risk assessment method really is trying to control or minimize the damage, not eliminate it, and I think what we need to be looking at is preventing, not minimizing or just trying to control it.
