A conservation researcher responds to Tory Bush’s bookBig feet. “
I was once talking with an environmental historian who made a comment that stuck in my mind: Humans are a species Homo Tinkerus. Their point was that self-control is difficult for people, especially in our environment—we like to change things up. Historically, these interventions have centered on human endeavors, such as explorers trying to recreate English gardens or hunters bringing favorite game to an area. But as the catastrophic effects of human activity on Earth’s ecosystems become undeniable, some humans have turned their reform drive to environmental modification to reverse the damage done to our species. And while there is merit in trying to right our wrongs, history has taught us that even pure intentions cannot protect against unexpected—and potentially dangerous—consequences.
The Tory Bush storyBig feetSimilar to a magazine feature for a New Yorker-esque fiction publication, Matter of Fact provides a dramatic example of humans tinkering with ecosystems, and potentially bizarre and unexpected environmental (as well as legal and social) ramifications. Describes Dr. Shelley, the unknown scientist at the heart of The story, of how Bigfeet—the genetically engineered approximation of the legendary cryptid—was created and then dropped into forests across North America, with little thought to what might happen to it or the other species they were coexisting with.
This fictional scenario has many real-world counterparts: In the 1920s, sport hunters released dozens of mountain goats on the Olympic Peninsula in western Washington state—the same area where some of the Bigfeet stories were set. Like Bigfeet, the mountain goat population has grown rapidly out of control. Goats have been causing trouble ever since, from eating sparse alpine vegetation to trying to lick Salt from the hikers’ clothing and equipment – There are no salt deposits naturally on the peninsula, but goats need it in their diet. As a result, federal and state land managers have had to carefully devise a multiyear system Planning to move or eradicate goats (including lifting some by helicopter to more suitable habitats).
The list of other examples is long: Rabbits in Australia (also for sport fishing), Invasive ornamental grasses in Arizonaand even The mice inadvertently escape to distant islands on ships. Each has resulted in problems in the ecosystem that then need to be rectified with further interventions, potentially causing a chain of additional consequences. The scientists working on the fictional Bigfeet Project had hoped to create a large herbivore that could serve as a food source for predators and add nutrients to the soil through its droppings, but over time, they also realized that their grand endeavor was, in essence, a billionaire’s revenge project. While Bigfeet is a huge hit with tourists and a global media phenomenon, it is already causing agricultural problems and threatening the food source and habitat of endangered species.
In the Pacific Northwest, Bigfeet begins to feed Stiff brushan endangered host plant Butterfly Taylor Extreme, to eliminate the number of butterflies. In response, the US government fines Bigfeet project magnate Thomas Bunch, who also faces jail time (despite his disappearance). But a symbolic fine and a few months behind bars do little to make up for the loss of a species. Butterflies are important pollinators and could be the canary in the coal mine for species in Bigfeet-invaded ecosystems, whose nutritional needs and preferences are still poorly understood and could lead to cascading destruction.
There are larger potential impacts from the introduction of Bigfeet, extending from local ecosystems. Through the climate crisis, humans are in the process of transforming every inch of the Earth, from the ocean floors to the mountain tops. Bigfeet is a chimera, created by combining the DNA of multiple animals, from extinct primates Gigantopithecus To bonobos and black bears. One of the animals included is the cow, which adds a moment of relief to the story when we learn of Bigfeet’s trick call. Livestock – and in Especially their burpsIt contributes significantly to climate change. Cow burps contain methane, a greenhouse gas that traps 28 to 34 times the heat carbon dioxide in the atmosphere. Cows and other livestock are responsible for 40% of global methane emissions. Bigfeet’s bovine heritage is doubly worrisome in terms of climate because they reproduce rapidly (which some observers in the story speculate could be thanks to rabbit DNA), compounding their environmental impacts.
The morals about all of this – in real life and in fiction – are mind-boggling. Mitigating human impacts on landscapes forces scientists and land managers to make difficult decisions. Judging the long-term effects of specific interventions requires a lot of research, and even then, not everything can be explained. Take, for example, the larger glider, a small long-tailed marsupial gone Locally extinct within Booderee National Park, Australia around 2010. One theory for its disappearance is that when land managers reduced red fox numbers, forest owls may have modified their diet, eating more gliders and eventually eliminating them.
Introducing a new species is not a decision land managers make lightly – hence the secrecy and lawless nature of Project Bunch. Although Bigfeet is a “designer species,” and was designed to keep in line with Sasquatch lore, culling actual historical species is a very real proposition, sometimes intended to hypothetically protect and enrich the environment. The woolly mammoth, which became extinct thousands of years ago, has been proposed as a target for de-extinction, and the scientist George Church is Trying hard to get them back to Siberia. He hypothesized that, by stomping around, mammoths could change the mossy-dominated Siberian landscape into a grassland, which would better sequester carbon and could help combat climate change.
Other proposals, such as those aimed at eliminating passenger pigeons, aim to correct an earlier human error. Passenger pigeons were once so numerous in North America that European settlers described the skies turning black at night due to their mass migrations. But poaching and habitat loss (thanks to settlers clearing forests for farming and logging) decimated their populations. The last passenger pigeon died in 1914; Proposals to reintroduce this species depend on modifying the genes of the band-tailed pigeon to mimic the traits of the passenger pigeon. Some scientists hope it will help de-extinction the passenger pigeon Restoration of forest regeneration cycles, leading to healthier, more biodiverse landscapes. In an ecosystem that hasn’t seen this species in over a century, this is a happy ending Away of content.
The revenge project described in Bush story provides a great example of the dangers of interfering with ecosystems; It also touches on the ethics of speciation manipulation and genetic modification. It could be a gene-editing technology like CRISPR-Cas9 Great tool With seemingly limitless uses. When looking at ecosystems, though, great thought and care is required in making decisions to use them. There have been many well-intentioned proposals to modify the species (though none as radical as creating the big-footed chimera), such as modifying bees to Resistance to parasites and viruses It can lead to the collapse of the colony, or Modification of mosquito populations To cause their death, and to protect humans from diseases such as malaria. Although tinkering with species and ecosystems is tempting for many reasons, from protecting endangered humans and animals to staving off massive damage caused by human activity, our tendency to meddle often leads to more tangled chains of cause and Effect.
