Recently, Brazilian forest advocate Antonio Nobre wrote: “Deforestation is climate action’s blind spot.”
He continues: “Since 2023, extreme weather events have shattered most model projections of the Intergovernmental Panel on Climate Change. Meteorologists are grappling with this new reality. Standard climate models were designed for a stable world that we have irrevocably left behind. But wait, there was a crucial omission. The dynamic land-atmosphere water cycle — powerfully mediated by living forests — has inexplicably been relegated to a mere footnote in the carbon story.”
This “dynamic land-atmosphere water cycle” is only one of many ways in which forests provide benefits to our climate, our fellow species and our society. And yet, deforestation in the United States continues at record levels.
In this course, instructor Hart Hagan will examine the ways in which trees and forests benefit our climate, while preventing flooding and drought and also providing habitat for a myriad of wildlife species. Hart brings his unique perspective and values to an exploration of the false notions, narratives and mythologies that are used to justify cutting down trees.
Participants will engage with a range of highly qualified experts, and we will ask and answer questions like these:
- What are the mechanisms within forests that cool our climate—through shade, water evaporation, water cycling, and sponge-like absorption that prevents floods, droughts, wildfires and extreme heat?
- What role do microbes, fungi and wild species play in the climate-regulating mechanisms of a forest?
- What is the difference between a forest and a tree plantation?
- What is the extent of logging in North America?
- How do we choose between a forest and a solar array?
- When is logging justified for solar installation?
- What’s the deal with biomass logging, and who benefits?
- What is forest thinning, and when is it recommended?
- Should we promote post-fire logging? Why or why not?
- How to identify timber industry propaganda
- How to protect wild species such as owls and woodpeckers
- What is the catastrophic wildfire narrative? How is it harmful and misleading?
- Under what circumstances do fires burn at higher intensity? What are the factors, and what can we do?
- When is wood the best building material, and when should we search for substitutes?
- Who are some of the leading experts whom we can trust for guidance?
- What can we do as a community to safeguard and restore our forests?
This will be a nuanced exploration of how to respect our forests while pushing back against false narratives that call for clearcutting, thinning, logging, burning and spraying.
Major issues to be addressed:
Learning how our forests work as ecosystems
In this course, you will learn what constitutes a healthy, high functioning forest ecosystem, which is biologically diverse, with many bees, butterflies, birds and small mammals, all of which require insects and their larvae, which in turn require a variety of native trees and dead wood.
Dead wood
We will explore the untold story of dead wood. Did you know that a dead tree is home to more species than a living tree? We will explore the value of dead wood—and why it’s important not to remove it from a forest— since it’s a source of food, water and shelter for myriad insects, birds, mammals and amphibians.
How caterpillars infuse energy into the forest ecosystem
We will learn the surprising importance of caterpillars, and the trees that support them. Did you know that just one pair of Carolina chickadees, each weighing ⅓ oz., require 6,000 caterpillars to raise their young in the spring? If you need 6,000 for one nest of baby chickadees, how much more do you need to support North America’s 2,000 bird species?
Wildfires
We will explore the causes, solutions and mythology around wildfires. We will discuss how homeowners can keep themselves and their homes safe and protected. We will look at the benefits of natural wildfires and the limitations of “prescribed burns.” Did you know that the black-backed woodpecker and the spotted owl are specifically adapted to thrive in a forest after a wildfire? The same is true of Melanophila beetles.
Timber industry talking points
We will study timber industry “talking points” so that we can identify them in the media. The timber industry uses terms like “fuel reduction” and “forest thinning” to extract the least flammable trees under the guise of wildfire prevention.
Biomass energy
The “biomass energy” industry cuts down our forests and burns them in place of coal. This is neither clean nor energy efficient. Nor is it smart from a carbon standpoint. Quite the opposite.

Anastassia Makarieva graduated from Leningrad Polytechnic Institute, Faculty of Physics and Mechanics, in 1996 and obtained her PhD in atmospheric physics from St. Petersburg State University in 2000. Since 1996, she has been working in the Theoretical Physics Division of Petersburg Nuclear Physics Institute investigating the life-environment interactions in the framework of the biotic regulation concept founded by Prof. Victor Gorshkov. In co-authorship with V.G. Gorshkov, Anastassia formulated the concept of the biotic pump of atmospheric moisture highlighting key ecological feedbacks on atmospheric moisture transport (2007) and, in cooperation with an international team of colleagues, demonstrated the existence of life’s metabolic optimum (broadly universal rate of energy consumption across life’s kingdoms) (2008). Combining theoretical work with field observations, Anastassia spent over sixty months doing forest research in the Russian wilderness. Her current research interests focus on deepening the physical understanding of ecosystem feedbacks on the water cycle and moisture transport.

John Feldman is a highly original and critically acclaimed filmmaker who works as a writer, director, cinematographer, and editor. His career spans over 40 years and covers a wide range of genres, including independent dramatic feature films, documentaries, experimental shorts, and educational films.
Feldman’s recent film Regenerating Life, How to cool the planet, feed the world, and live happily ever after (2023) looks at the climate crisis from an ecological perspective. Screening globally, it is translated into 11 languages. “John Feldman’s film is a masterpiece in which he puts life, in terms of healthy ecosystems, centre-stage as the Earth’s extraordinary global-temperature regulator. (Peter Bunyard, The Ecologist Magazine, UK).
Symbiotic Earth: How Lynn Margulis Rocked the Boat and Started a Scientific Revoultion (2018), “is a vivid portrait of a bold scientist who took us to an understanding of evolution very different than any previous one. This film represents an effervescent intelligence leading the way to a revolution in understanding life on Earth.” (Thomas Lovejoy, Professor, George Mason University, known as “The Godfather of Biodiversity”)
