An update on that info.

'Farming is the main cause of the springtime smog that affects western Europe each year. In 2014, Paris banned half of its traffic in a vain effort to control a spring smog. The health benefits from tacking agricultural ammonia are huge.'
If good farming, and the good food that springs from good farming, and all the associated public goods that spring from those good things, was placed back at the centre of government policy, where it should be, we might stand a chance.
As it is, agriculturalists have been relentlessly pushed to industrialise, and to engage in practices that make other people wealthy, whilst seeing their own farm gate returns be squeezed to almost zero.
It's not the fault of farmers.
It's the whole food system that has been f*cked over for decades, for the short term gain of the extractive commodity supplier, or commodity buyer.
It's doesn't serve public health, or wellbeing, it doesn't serve farmers.
But hey what do us lumpen rusticles know about any of it, eh??
