You can't do this job unless you're advocating for better environmental management, advocating for more critical thinking about how you approach the management of natural capital, and advocating for the intelligent and sharper uses of the tools that we use in our economies and societies.
I'll give you an example. We did a piece of work looking at the use of economic instruments to improve the management of waste systems in New Zealand. We said, here's a whole bundle of tools that we're not using well. In that case, we advocated that much more critical thinking be put around, and the critical application of economic instruments be made to, the management of waste flows.
The role of advocacy is simply a way of saying that the role is to argue critically for more constructive ways of getting to good environmental outcomes, for greater efficiency in the use of resources, for living within the planet's limits, and for all the things that we're so familiar with.
