A tiny organism called pollen pulls off one of nature’s key tasks: plant reproduction. Pollination involves a complex network of different species interacting with one another and mutually adapting to their ecosystems, which are constantly changing.

Some pollen grains require just a puff of wind to set them in motion, but most plants depend on creatures gifted with mobility. These might be birds, bats, reptiles, or insects including butterflies, beetles, flies, wasps, and over twenty thousand species of bee. In Paths of Pollen Stephen Humphrey asks readers to imagine a tipping point where plants and pollinators can no longer adapt to stressors such as urbanization, modern agriculture, and global climate change. Illuminating the science of pollination ecology through evocative encounters with biologists, conservationists, and beekeepers, Humphrey illustrates the significance of pollination to such diverse concerns as food supply, biodiversity, rising global temperatures, and the resilience of landscapes.

As human actions erase habitats and raise the planet’s temperature, plant diversity is dropping and a growing list of pollinators faces decline or even extinction. Paths of Pollen chronicles pollen’s vital mission to spread plant genes, from the prehistoric past to the present, while looking towards an ecologically uncertain future.

Stephen Humphrey is a writer, radio contributor, and citizen naturalist originally from Western Canada, now based in Toronto.

Stephen Humphrey's profile page

“Stephen Humphrey is a highly accomplished, and engaging storyteller. In the manner of Carl Sagan or Aldo Leopold, he calls attention to little-known or misunderstood topics, and presents these to an often science-hostile public. Paths of Pollen advances the cause of pollinator and plant conservation for their benefits to all humankind and wildlife, now and in the future. I couldn’t put it down.” Stephen Buchmann, author of *What a Bee Knows: Exploring the Thoughts, Memories, and Personalities of Bees *

“With Paths of Pollen, Humphrey has extended an accessible invitation to consider these relationships at multiple scales, from the wide view of global environmental activism to the microscopic perspective of a grain of pollen.” *Montreal Review of Books *
