Halloween is approaching. Stay sane — and sustainable.

Here are some common dilemmas that arise on Oct. 31, along with tips and tricks to get you through the night.

• No costume? Turn your last-minute costume into an environmental statement. Be a glacier from 2050 by carrying around a glass of water. Or take a dip in the local pond to dress as a toxic algal bloom. Better yet, dress in orange and throw around some silly string. You’d be a stellar wildfire.
• Candy is bad. What to do? From homemade “apple mummies” to store-bought fruit leather, try handing out these healthier, greener treats to the toddler-sized bumblebees that come to your door.
• Bored? Vacuum up your precious free time by turning jack-o-lantern innards into squash soup and making your own lead-free face paint. While you’re at it, bring out your crafty side by turning candy wrappers into … something. (Still bored? Here’s a list of beers to pair with your kid’s Halloween candy.)
• Fretting about the election? One option: Distract yourself by spending extra money on costumes and candy. That’s what most Americans do during election years. But you know better! Save your cash and watch these Trump-free scary movies that are secretly about the environment.

Be prepared, not pre-scared.
