This passage is from A. R. Kirchoff, “The New Ecosystems of the Anthropocene" ©2017 by College Hill Coaching.
Scavengers—animals that feed on carcasses,
rotting plants, or waste—get a bad rap.
Yellowjackets and raccoons swarming around
garbage cans can seem like annoying pests at
(5) best and germ-infested monsters at worst. Indeed,
scavengers have been known to spread diseases
such as meningitis, leptospirosis, and bubonic
plague, so it's no surprise that they are the focus
of a huge extermination industry. But our habit of
(10) eradicating irksome species ignores an important
fact: scavenger relationships are essential to all
complex life.
The selective pressures of scavenger behavior
accelerate the evolution of social intelligence.
(15) For thousands of generations, some scavenger
species have struggled to outwit the wily hunters
with whom they compete for scraps. They
must predict, plan, and communicate as they
approach a carcass in order to avoid becoming
(20) the next prey. At the same time, hunters like
Homo sapiens had to become more clever to
protect their meat from these thieves. This social
interaction has allowed at least one scavenger
species to thrive in an anthropocentric* world:
(25) Canis lupus familiaris—the domesticated dog.
Your pet terrier would not be such a faithful
companion if its ancestor, the grey wolf, had
not spend so much time picking over the trash
of our hunter forebears. In just 20,000 years, we
(30) have become symbionts,* turning a few lines of
wolves from freeloading foragers into friendly
Frisbee-fetchers.
Even less perspicacious scavengers play
a vital role in complex ecosystems, often in
(35) unexpected ways. As plastic waste accumulates
rapidly in the ocean (and is expected to surpass
the total mass of fish by 2050), and toxic
chemical waste continues to be dumped into
our water supplies, the role of one particular
(40) class of scavenger, the decomposers, has become
critical. These creatures break down complex
molecules into simpler ones in a process called
biodegradation. Alcanivorax borkumensis, a
naturally occurring marine bacterium, can
(45) digest petroleum and convert it into food
energy. Hydrocarbons like petroleum and
plastics are energy-rich organic molecules
much like starches, fats, and proteins, so
the idea that they can be used as food by
(50) opportunistic organisms is not so biochemically
far-fetched. After crude oil spills, cleanup
crews encourage this biodegradation by using
chemical dispersant to break the petroleum
into smaller droplets, thereby creating more
(55) surface area for the bacteria to attack. Another
decomposer, Aspergillus tubingensis, is able to
greatly accelerate the breakdown of polyester
polyurethane, a petroleum product and one of
the more durable plastics in our landfills and
(60) oceans. Although environmentalists have yet
to discover a practical method for harnessing
A. tubingensis in large-scale waste mitigation
systems, such bio-technological solutions may
not be far off.
(65) Our dependence on unicellular opportunists
goes deeper still: our digestive processes,
blood pressure, and immune system depend
on thousands of species of scavenger bacteria
that live primarily in our gut and make up our
(70) microbiome. These organisms patrol the intricate
chemical pathways of the gut and perform duties
that, under normal circumstances, keep things
running smoothly. The overuse of antibiotics,
our favorite pharmaceutical pest-control system,
(75) often compromise healthy systemic function by
destroying healthful bacteria as well as harmful
ones. For instance, humans with depleted levels
of Butyricicoccus pullicaecorum in their intestines
have higher rates of chronic bowel diseases like
(80) ulcerative colitis and Crohn's disease. Research
into how these microorganisms has exploded
in recent years, particularly regarding how they
interact with human chemistry to regulate our
hormones, our blood sugar, and even our mood.
* human-centered
* species that live together in a mutually supportive relationship.
