An audacious plan for rewilding every city on Earth

Mind-bendingly original and full of intricate illustrations, Ultrawild is a unique book, containing over one hundred outrageously funny, scientifically plausible inventions for rewilding cities and saving the planet.

Join maverick inventor Steve Mushin as he tackles climate change with an avalanche of mind-bending, scientifically plausible inventions to rewild cities and save the planet.
Jump into his brain as he designs habitat-printing robot birds and water-filtering sewer submarines, calculates how far compost cannons can blast seed bombs (over a kilometre), brainstorms biomaterials with scientists and engineers, studies ecosystems and develops a deadly serious plan to transform cities into jungles, rewilding them into carbon-sucking mega-habitats for all species, and as fast as possible.
Through marvellously designed and hilarious engineering ideas, Mushin shares his vision for super-high-tech urban rewilding, covering the science of climate change, futuristic materials and foods, bio reactors, soil, forest ecosystems, mechanical flight, solar thermal power and working out just how fast we could actually turn roads into jungles, absorb carbon and reverse climate change.
Written and illustrated by Steve Mushin

This is a big format hardcover book that requires an A3 courier satchel.


Claire Mabey, The Spinoff, Aotearoa Books of the Year, 2023 ~ This visionary, intricate, outrageous road map for integrated thinking is mind blowing. It’s funny, it’s a melding of engineering, hi-tech, botany, zoology and pure creative thinking. Required reading for everyone, most especially political leaders and those feeling like we’ve run out of ideas: this book proves we really haven’t.

The School Library, Read NZ ~ This brilliant conversation-starter will rewire how young readers perceive “environmentalism,” fusing creativity and science while spotlighting nature’s splendour. Brimming with humour and hope, ‘Ultra Wild’ shows Earth’s magnificent ecosystems still have a fighting chance if we unleash our imagination in time. What wild innovations might we dream up together? Mushin hands us the mantle to find out. Read the full review.


About the author

Steve Mushin is an industrial designer, artist and inventor who collaborates with scientists and engineers to solve perplexing problems that no one else seems to know what to do about – like what can be done with explosive cow gas or how to make bikes fly or cities transform into jungles as fast as possible. Steve has exhibited large-scale design drawings and models around Australia and in Japan. He works between Australia and Aotearoa New Zealand, and in 2015 received an Australian Design Honours award for his work in sustainable futures thinking. Ultrawild is Steve’s first book.
