BRS SEMINAR SERIES TOGETHER WITH THE MURRAY-DARLING BASIN COMMISSION PRESENT:
A SPECIAL BRS SEMINAR Tuesday 21 March
Water: a crucial factor for sustainable futures
Professor Ian Lowe AO, ACF President
Water is essential for life; not just for humans, but for plants and animals. We are not using either the surface water or the
groundwater of the Earth sustainably at present. Our misuse of water is a significant contributor to the major extinction event now
occurring. For both ecological and economic reasons, we need to change the pattern of supply and use of water. This is necessary for
us to achieve the goal of a sustainable future.
