As summer comes to an end, we’re revisiting our book club special on Tim Lilburn’s Kill-site, a collection of poems exploring ecology, colonialism and spirituality through the landscape of Southern Saskatchewan. But don’t be scared off! We’ll also dip into a children’s classic, Dennis Lee’s Alligator Pie.
It’s the end of summer, and that means a conclusion to the Terra Informa Summer Book Club. This month, we read Tim Lilburn’s Kill-site, a collection of poems exploring ecology, colonialism and spirituality through the landscape of Southern Saskatchewan. For the children’s segment, we tackle a classic, Dennis Lee’s Alligator Pie.
Today we talk to a researcher who is investigating how climate change is affecting the way that wild fires interact with forest ecosystems, we explore the colonial concept of Terra Nullius and how it ties in with modern environmental issues, and we hear from a biologist who is studying the accumulation of mercury in the fish we eat. All that, plus your wrap up of the week’s news headlines, on today’s edition of Terra Informa.

What is the Doctrine of Discovery or terra nullius? Today on the first episode of Decolonize Your Mind, a segment that looks at environmental issues with a decolonizing lens, we ask this question, along with a bunch of others. What’s colonization? And what is the responsibility of environmentalists to look at these kinds of things? We’ll also hear an audio clip from Winona LaDuke, speaking about the impacts of the Doctrine of Discovery and some of her thoughts on empire.
Effect of Climate Change on Forest Fires
Across North America we’re getting into the thick of forest fire season. Have you ever wondered how fires change the forests they burn, though? Or how that might change now that fires are coming more often, and getting more intense? Terra Informa’s Chris Chang-Yen Phillips reached University of Saskatchewan ecologist Jill Johnstone in the Yukon to ask her about her research studying fire in forests there. She explained how climate change is making fire a disruptor of boreal forests, rather than a regenerator.
Mercury in Fish
Most people consider fish to be a healthy dinner choice, and for the most part, they’re right. But there is a complication – some fish species can absorb mercury, a toxic heavy metal. Some of this mercury is natural, and some of it is from industrial pollution. Can anything be done? And what species of fish should we be wary of? Today Terra Informa correspondent David Kaczan chats to Tina Willson, a researcher at the University of Wyoming.
