We can all help ourselves and each other to a certain extent.

I've heard that ash from the fireplace can be used as grit for paths. I'll save some and chuck it on the pavement the next time it threatens to snow (though I hope I won't be fined for littering!). And as for pedestrians, it may be worth investing in shoe chains (I kid you not), tried on a pair today and they really do help with walking on ice and snow.
