We grow food in the soil. We dig in it, play in it, build from it, and build over it. We depend on it, but we don’t always know much about it or who lives in it. Soil ecologist and science filmmaker Maxwell Helmberger aims to change that with his claymation shorts about soil ecology and biodiversity.
As an entomology Ph.D. student studying the soil invertebrate response to microplastics, Helmberger is on a mission “to expand the world’s knowledge of and appreciation for the weird and wonderful world beneath our feet,” prioritizing topics for which little or no video material exists. In an email interview with TKSST, Helmberger provides an example:
For the soil food web video, I actually did have to do a little research, though what I needed wouldn’t be found in any written work. I needed to know how exactly certain types of mites walked, so I extracted some of those mites from soil, put them in a plaster dish under a microscope, and used my phone to record slow-motion video of them walking, so I could see exactly which legs moved when and how they moved.
Next, learn about Earthworm Effects on Soil: The Good, the Bad, and the Ugly, a video that emphasizes “the fact that while they can be good in some soils, they can negatively affect other soil environments, especially when they are invasive.”
“Therefore, they should not be carelessly introduced to new soils. Moral of the story, don’t dump your bait.”
In Ecosystem Services in Agriculture, Helmberger introduces the environmental benefits of the small creatures that you might not normally notice on a farm, like earthworms, bees, and ladybugs, also called ladybeetles and ladybirds. A definition via the National Wildlife Federation:
soil, ecology, and sustainability:
“An ecosystem service is any positive benefit that wildlife or ecosystems provide to people. The benefits can be direct or indirect—small or large.”
