DON'T use it!!!
There are obvious exceptions that we can't avoid. But we're intelligent people, and I'll not dwell on those things. I'm talking more things that we use for the supposed convenience, when really, the non-throw-away alternative is not so terribly un-convenient. There are things that are made to be disposable, but when you have a non-disposable alternative, why not use that instead?
Forks, knives, spoons? Easy to avoid. ESPECIALLY in the home. For outdoor activities, get bamboo utensils or hit the thrift store and get a set you won't care about if any gets lost. I can't quite recommend the compostable ones, unless you are a really good composter. They resemble plastic too much and they get in the recycling, and we're not good at dealing with that yet. Better to reuse a set from the thrift store, for sure. Those were already made!
There are SO many ways we can save resources. Easing away (or going cold turkey) on disposable stuff would be such a giant help... let's try it. Let's all work on consuming less of everything. We'll be healthier, and the planet will be healthier, and that will make us healthier... it's a perfect circle.
