22 Modern Monsters Threatening our Environment (and What You Can Do to Defeat Them!)

Have a sneak peak look inside Planet SOS!

The fearsome Atmosdragon is heating the planet and causing global warming, while the bright-eyed Glareworm is busy creating light pollution and the Smogosaurus is filling our air with toxic fumes. Each of these beasts is wreaking havoc on our planet and we need heroes – could you be one of them?

In all, 22 monsters are featured in Planet SOS and each of them is accompanied by a Monster Card outlining the big, bad beasts’ weaknesses and how to use each one to your advantage. Mythical monsters have always represented humanity’s greatest fears, and the environmental monsters in Planet SOS are no different. Each is paired with the mythological beast it is based on.

Planet SOS is the perfect handbook for any eco-hero who wants to learn about our global environmental crisis!

Youth Services Book Review

"Rohde presents twenty-two different aspects of the crisis that is engulfing our planet – and she does it in a unique, creative and accessible way."

Ben Harris, Just Imagine

"Each double-page spread in this colourful, informative and highly original book presents a ‘monster’ that threatens the Earth … Environmental issues are brought to life here and dramatically connected to the child-reader … I am always delighted to see nonfiction books presented to children in creative and appealing ways: this book, in particular, is a hugely impressive example of just that."

Read it, Daddy! Blog

"If you find that your own kids, or your own classes at school are groaning every time they hear or see anything about climate change or ecological disaster, this book might just change their minds and bring them back around in a fantastic way. Mixing real-world climate threats with myth and legend is an utterly genius idea and this book is one of the most impressive titles on the subject we've seen to date on the blog."

Miss Cleveland is Reading Blog

Intriguing, imaginative and inspiring, Planet SOS is an information book with a difference. Merging mythical monsters, environmental emergencies and monster cards, this is sure to engage the most reluctant of readers ... With a glorious world map and timeline, comprehensive glossary and source list, it’s eye-catching, accessible and gives sites for further exploration. And, as a pleasure read, it’s a delight for budding environmentalist. A must for every school library!”

Publishers Weekly

"This ambitious exploration of environmental threats, including smog, deforestation, and oil spills, characterizes each as a vanquishable monster. Rohde’s textural digital art ensures there is plenty to look at on each oversize page. While this compendium is text-heavy, clear prose and character cards offer a novel way to encourage environmentalism."
