I am an ecologically-minded writer/illustrator, speaker & consultant, with a background in biology & chemistry, architecture, and civil engineering, living in Toronto.
Since age 14 when I read Silent Spring by Rachel Carson, I have been ecologically minded and have shaped my education around learning whatever I thought I would need to ameliorate our health and our environment. First, I studied biology & chemistry (B. Sc., University of Waterloo), which allowed me to understand nature including our bodily health. Then, realizing that a lot of the problems – and solutions – are in how we design our cities, I studied civil engineering (B. A. Sc. University of Toronto). Next, because I love art and design, I studied a bit of architecture (Certificate, Ryerson University). Finally, I put it all together with a Ph. D. in civil engineering at the University of Toronto focussed on how to design resilient communities and cities.
Over the years, I have worked at companies such as Ontario Power Generation, Stevens Burgess Architects, and Rivercourt Engineering and participated in a variety of grass-roots community groups.
Recently, I wrote my first book, which you can read about below. Thank you for visiting my website!

Where does it all come from? Where does it all go? Toronto’s water, energy, and waste systems
In a big city like Toronto, it’s easy to live disconnected from the environment that supports us each day. Many of us do not know where our water or energy comes from or where our waste goes. This Toronto-specific picture book answers these questions for Torontonians of all ages and backgrounds in a simple and fun way. Looking at maps, readers can get to know specifically how they fit into the larger picture. Once we know where things come from and where things go, we are no longer lost. We are connected, and have a foundation upon which to develop a caring relationship with our environment.

endorsements & testimonials
“This book communicates basic facts all of us need to know in order to see our part in the overall environment. Thank you, Mariko, for this important book for Toronto.
This information will help us understand what actions we can take in our communities, workplaces, and civil society to ensure a sustainable future.
Plus it’s delightful; my 5-year old grandson loves it.”
– Dr. Dianne Saxe, environmental and climate lawyer and president of Saxe Facts
and former Environmental Commissioner of Ontario
“Hi Mariko, I love your book. It’s clear and straightforward.
The illustrations and the cat especially shine through and carry us from
beginning to end as does the prose which is suitable for adults and children alike.
After I put it down, I thought a great sequel might be
“Where does food grow in Toronto?””
– Sandra Campbell, Author of Getting to Normal
and producer of eco-arts projects in the Greater Toronto Area
“My toddler loves this book and we often read it prior to “nap” time. The only problem is he’s now in his crib yelling “ASHBRIDGES BAY TREATMENT PLANT!” to himself repeatedly at full volume, instead of napping… Thanks all the same, @mariko_uda!” (on twitter)
– Joe Moed, Toronto father
“Mariko, my 8-year old loves your book! They love the story, illustrations and that they can colour it. It’s been a while since they were so enthusiastic about a book. Good luck with getting the word out – more children need to see this book! And I loved it too :)”
– Sandra Luz, Toronto mother of two
“A great picture book guide for anyone who has ever wondered where their tap water, electricity, space and water heating comes from or where their toilet/drain/poop/rain water goes. Find out where it all comes from and where it all goes in Toronto! Also, a good tool for provoking discussions about the environment and our current global environmental crisis. We are happy to have it as part of our library collection.“
– Rotem Anna Diamant, Librarian and Founder Canada Comics Open Library
