Let’s wean our city off poisons

There’s many ways to control weeds without toxic spray

some things boggle the mind. Like infinity. And how we’ve used the past 100 years of human smarts and innovation to create a world awash in synthetic poisons and toxic microplast­ics. And why we’re so quiet about it. I occasional­ly hear from locals concerned about the use of weedkiller­s in our playground­s, schools, sports fields, waterways and roads. But it’s pretty sparse, and there’s yet to be any collective action.

I know we’re all busy, but are poisons in our public spaces and waterways something we are truly okay with? I doubt it.

There are proven ways to control weeds without toxic sprays. In Taranaki, playground weeds have been suppressed with sawdust instead of synthetic sprays. Weeds in footpaths and streets can be controlled with steam. Organic and spray-free growing are well-proven ways to produce healthier food.

Why, then, do we keep using poisons in some of our most sensitive spaces? Places with kids and pollinator­s and pets and nature.

It seems that, like a chain smoker, we’ve grown addicted. And silent. In many years of hearing public input to local council plans, policies and budgets, there’s been little, if any, citizen commentary questionin­g the use of weedkiller­s and other poisons.

An online search shows council reports are silent on where weed killers and other poisons are used in Palmerston North, and in what quantities. We know where every dollar comes from and where it goes. But when it comes to poisons, we know very little. Horizons Regional Council occasional­ly reports on herbicides and other poisons in rural wells, but that’s about it.

Some communitie­s have made progress against poison sprays in recent years, notably Christchur­ch. These plucky Cantabrian­s have convinced the council to curb glyphosate use, through a strong citizen-led campaign.

Billions of dollars have been awarded in lawsuits against Monsanto and Bayer. Do local councils face any public liability in the use of glyphosate?

It’s not just a city thing. Farmers are often highly reliant on poisons. What little testing is done shows a remarkable number of water wells are contaminat­ed with these chemicals. A recent survey shows nearly one in 10 wells are contaminat­ed. While almost all were below levels proven to harm human health, these persistent chemicals will continue accumulati­ng unless stopped at the source.

From a human and environmen­tal health point of view, it’s time for communitie­s and councils to start weaning ourselves off the herbicide addiction, and on to more people and plant-friendly solutions.

Our family-friendly city of Palmerston North would benefit from spray-free playground­s, waterways and sports fields and school grounds.

To help wean our city off poisons in public spaces and waterways, an easy step is to start talking about it. Will you?
