Jamie Mackay hosted a debate on water quality between Professor Jacqueline Rowarth and Dr Mike Joy on The Country yesterday.
. . . When discussing the fencing of waterways and keeping stock away from streams and rivers, Dr Joy said animals should be out of the food chain by 2050 for other reasons too including climate change and energy transfer.
Professor Rowarth said there is no evidence intensive dairy farming caused the Havelock North water contamination crisis and that the solution lies with smarter feeding of cows and better systems to capture and utilise effluent and nitrogen run-off.
