About
Planet Earth Journal is an independent nature publication created for curious minds.
What you’ll find here
Stories about remarkable animals and places, a collection of checked fun facts, practical ways to help nature, and the Daily Challenge — a quiz for anyone who likes to learn something new.
How we check facts
We write every story in our own words. Factual claims are checked against reliable sources such as scientific institutions, museums, universities, government agencies and nature organisations. Each source is recorded together with the date we checked it.
Fun facts and quiz questions come from a fixed, checked collection. Nothing on this site is generated automatically. If we cannot confirm a claim, it is not published.
Sources under every story
Every story ends with the list of sources it is based on, and each figure in “At a glance” links to where it came from. Fun facts and quiz answers show their source too.
About our images
None of the images that open our stories are photographs. Some are detailed digital illustrations created with the help of AI tools; others are simple drawn cover art in our own house style. They set the scene for a story; the facts in each story come from the sources listed under it. Because an illustration can differ from the real animal in small details, please don’t use our story images to identify a species.
The Daily Challenge never uses illustrations. Its photo questions will only appear once real photographs with a licence that allows reuse have been checked, and each of those photographs will be credited to its photographer. They are described for screen readers without giving the answer away.
