Ice is extremely dangerous, it cannot be left, people have to use salt (or another product), and use it properly to manage the risk.

Sand. Works even in 30C below zero, is inexpensive, has plentiful supplies, and has no negative environmental effects.
Sand is an option, but it isn't as effective as salt at temperatures where salt functions well. And sand does have negative environmental effects, it blocks up drainage channels--which are natural areas. Nothing is without its tradeoffs.
