About the Holiday
In December of 2013 the United Nations General Assembly proclaimed March 3rd as World Wildlife Day to promote awareness of our environment and the dangers to it. Every year a different theme is chosen to spotlight an area of the world, a particular species, or a group of activists. This year’s theme is “Wildlife Conservation Finance: Investing in People and Planet” and focuses on innovative ideas for financing can contribute to halting biodiversity loss, raising the interest of private sector stakeholders to invest in wildlife conservation, and creating a sustainable future. The day also celebrates successful conservation and sustainability initiatives. To learn more about the day, special events, and how you and your kids can get involved today and throughout the year, visit the World Wildlife Day website.
Thanks to Eerdman’s Books for Young Readers for gifting us a copy of Kingdoms of Life for review.

Kingdoms of Life
By Carly Allen-Fletcher
“Life is all around us…In the sky, the sea, and the soil, life exists in millions of different incredible ways.”
Jump into Carly Allen-Fletcher’s vibrant fact-filled guidebook for kids for a deep-dive exploration of the kingdoms of life. Each Kingdom rules over its own color-coded section, jam-packed with information on how the classified organisms feed, grow, and reproduce. Information also includes the ways in which the organisms across Kingdoms are related or work together with other lifeforms. The pages are royally packed with vibrant illustrations that appear to burst out from the very edges of the book.
Allen-Fletcher begins with an explanation of how all life is formed—from tiny building blocks called cells. These cells can join to create complex multicellular life forms or just exist on their own as unicellular forms of life. She then zooms out to examine the six biggest categories of life. Allen-Fletcher makes sure to note that these categories are not fixed; they change as scientists learn more and arrange beings in different ways.

The first category investigated in depth is the most complex of the life-form groups—animals. The animal pages are filled with a diverse range of species, each numerated to a corresponding key at the back. Allen-Fletcher shows the wide range of animals by comparing the smallest species (fairy wasps) to the largest (blue whales), while also explaining how even within one species (dogs) there can be glorious variety. Examples of animals that don’t quite fit in the animal category, such as a sea slug that can make energy from the sun, as well as animals that can survive extreme conditions or are thought to be practically immortal, are also discussed.
In addition to the animals, plants, fungi, protists, bacteria, and archaea are each given equal attention in their respective kingdom sections. From protists like giant kelp and slime mold to bacteria in our gut and bioluminescent bacteria found in squid, each kingdom is filled with fascinating examples of life and interesting facts on specific organisms.

Kingdoms, Allen-Fletcher explains, can also be broken down further, into smaller and smaller groups such as family, genus, and species. A few taxonomists (scientists who study and sort lifeforms into categories) from around the world and throughout many different centuries are highlighted for their contributions to the field.
The book ends with a last dose of wonder: “We know more about the moon than we do about the deepest parts of our oceans. / Every year, we learn more about our home and the incredible life-forms we share it with. / What will we discover next?” The inclusion of “we” in this ending invites readers to feel welcome in this process of study and discovery. Taxonomy need not be only for adult scientists, but anyone who shares a passion for nature and careful observation.
Back matter features each of the categories taxonomists use to sort life into groups as well as all the names of the featured life-forms throughout the book. The science is detailed while also distributed into easy-to-read bite-sized chunks.

Carly Allen-Fletcher illuminates a topic that is usually reserved for upper-level biology courses making it accessible and intriguing for young learners. The facts from her book will inspire a passion for all species—large or small, animal or bacteria—and help children to understand where in this big wide world we as humans stand and the symbiotic relationships that exist between creatures. Mini scientists dot the lusciously illustrated pages, comically examining life-forms in all the kingdoms up close.
Kingdoms of Life would make a valuable addition to home, school and library collections.
Ages 6 – 10

- As Allen-Fletcher notes in Kingdoms of Life, scientists are constantly evolving the categories for living organisms as they learn more. Do you notice any differences between the book and video kingdom categories? Since this video was published, scientists have started using the kingdom names bacteria and archaea instead of the previously used term, monera!
