Trick or treaters have already started to arrive in their bright and colorful costumes. Most of them have various shake lights attached as well as reflectors, making them visible to cars.
Candy has been de-emphasized over the years due to the damage it can cause, but a lot of sugar free substitutions still make the grade. A lot of the left over candies from the year are broken down for biofuels.
It's a good night to keep the lights low, keep things scary while we wait on the porch, but it's not totally dark- bio-luminescent pumpkins glow on the porch. They're really more a novelty to the more practical glow plants, spliced genetically with fireflies and some deep ocean creatures, bright bulb like structures glowing far brighter, but they work to make it spooky- and still quite edible. The lights can be a little unreliable indoors without sun exposure, but they do a dynamite job for most outdoor lighting.
The bugzapper plant glows and crackles in the night, eliminating local mosquitoes. It's current is relatively weak compared to some of the big factory style electric plants, but it does the job.
I take a deep whiff of the night air as the next group of kids comes to claim some goodies.
"Trick or treat!" the little ghouls yell. They cringe at my makeup job, green with bolts in my neck. But they don't flinch at the plants surrounding them, the real Frankenstein's monsters- but why would they? They weren't natural, but they provided light, electricity, while making more oxygen rather than less. If only we'd had the technology just a little sooner, the stars in the sky would be a little more bright.
