My first piece for the Observer is about saving the world's fireflies

Nori Yuasa/Getty Images It's taken me almost 13 years in journalism but I've finally got around to getting a piece published in the Guardian - or rather, in the Observer , which is the Sunday version of the Guardian.

The story is called "Why the lights are going out for fireflies". It explores why the world's firefly populations are in decline, and what we might do about it.

It's probably for the best that the editors didn't take up my proposal to call it "Grave of the fireflies", after the saddest film ever made. For one thing, this story has a hopeful ending.
