The simple reality these days is that no dairy cow can get into a stream thanks to dairy farmers having fenced off 97 per cent of significant waterways on farms.
And that's only the start. Dairy farmers are also planting the riparian strip between the waterway and the fence, restoring wetland areas and establishing new ones - all to remove contaminates before they reach the water. They have also installed sophisticated on-farm effluent management systems, and many have retired sensitive areas of their land, often placing them under protective covenant. In many regions farmers are going even further as they work towards meeting nutrient limits through changes in farm practices and systems.
Yes, just as there are some laggards in most sectors, there are still some farmers who need to up their game, but these cartoons show there is a lack of understanding of what modern dairy farming is about, and therefore the picture they cast is far from reality.
Sediment, bacteria, nitrogen and phosphorus - as well as heavy metals from urban areas - all have an impact on water quality in New Zealand.
The burning issues all Kiwis need to address, including farmers, is how these contaminants are getting into our waterways, and what does each one of us need to do to reduce our collective footprint.
I can't go past noting the sheer frustration expressed on social media this week from farmers at the apparent hypocrisy shown by those organisations and businesses that regularly criticise dairy, and their reluctance to publicly call out concerns over urban or wildlife induced environmental pollution.
Clear examples are human waste contamination of Auckland beaches and even the E. coli contamination of Queenstown's Lake Wakatipu possibly from freedom campers and/or wildlife (in this case ducks). Are they so concerned for their balance sheets that criticising urban pollution has become a sacred cow?
Every one of us, including people living within city limits, has the potential to contaminate waterways for the simple fact that what we put down any drain can end up in our oceans and on our beaches, or in our rivers.
Dairy farmers and the wider dairy sector believe so strongly that collectively we can all look after our streams, rivers and beaches that we're taking a leadership stand.
Let's all do our bit and start a movement in New Zealand to change how we all look after our waterways.
The Vision is Clear - and we all have the same vision. So, let's get behind it, work together and stop pointing the finger at one group of people who are already working hard to look after their part of New Zealand.
