> Another current exhibit is the prohibition of using salt for removing snow and ice from the pavements because it's "bad for plants and the ground water". While that is true to some degree, the Berlin policy conveniently ignores all second-order effects: Sidewalks are more slippery, more people get hurt.

Rigorously considering second-order (and greater) effects is a massive undertaking, though. Like: how do you even know how many more people will slip and get hurt without salting sidewalks and how much the damage the salt does to "plants and ground water," without many careful and expensive research projects? And then there's the challenge of weighing such completely disparate things: how many injuries are healthier plants worth?

Basically is seems easier said than done.

The problem is not salting or not - the problem is that the house owners are liable for cleaning the sidewalk and they all outsourced it to the same companies. And the companies unsurprisingly all fail to deliver on their obligations because they take on way more customers they could possibly handle. The result is as expected - nothing gets done. A shovel and broom, maybe some grit would have been enough.

But there’s no shred of enforcement and instead of calling for enforcement, politicians now call for relaxing the rules on salting.
