Somebody put a machine on the windowsill that eats light, and everyone here calls it decoration.
Look closely at a single leaf. It is running a reaction that our best laboratories cannot replicate at room temperature without an industrial mess of catalysts and heat. Inside each cell sit stacks of green machinery, and when a photon arrives, a bundle of light that has traveled eight minutes across ninety-three million miles of vacuum, the leaf catches it and uses that energy to rip a water molecule apart.
It pries the hydrogen off the oxygen. The oxygen it simply discards, exhales, throws away as waste, and that waste is the air filling your lungs right now. Every breath you take was garbage to a plant.
The carbon is the part that stops me. The plant pulls carbon dioxide straight out of the room, invisible, weightless-seeming, and welds those carbon atoms into sugar, into stem, into the very structure standing on the sill. It is building its own body out of air and light. When you water it and watch it grow heavier, that added mass did not come mostly from the soil.
It came from the sky. You are watching a thing knit itself out of atmosphere.
And it does this in silence, with no moving parts, powered entirely by a fusion reactor it will never touch, running the single reaction that put breathable oxygen into this planet's air two billion years ago and made animals like us possible at all.
You wanted to know if it looks a little sad by the window.
It is quietly performing the chemistry that invented you.
