No simple fix to dirty waterways

OPINION by Pattrick Smellie : Much reporting of the prime minister's chief science advisor Sir Peter Gluckman's research into freshwater resources seemed to shred further the Government's tenuous credibility on this increasingly politicised issue.

Its uncontroversial observation - that human activity in both cities and on farms is at the root of freshwater degradation – was routinely treated as if it were a key finding.
