Articles About Landfill
These changes will happen at evolution’s grindingly slow pace, but by the time these creatures have gotten used to life in vast ecosystems of garbage, a future researcher will marvel at how readily and how ingeniously these creatures have adapted — and continue to adapt — to their befouled environs.
This week’s entry discusses the myriad mammals that are able to live in a landfill, from small rodents to upper-echelon predators to human beings. But this is a Pyrrhic victory, as they are subject to the same hazards that afflict any creature searching its way through a dump.
Many bird species that call the Rumpke grasslands home: birdsong mixes with the rattle and hum of machinery to create a cyborg symphony that represents the in/organic mix that is the landfill itself.
Insects are important to the decomposition of garbage because they eat a lot of trash and tunnel their way through it, which mixes and aerates it. Some insects find their way to the trash, while some are inadvertently brought to it. In interesting case of filth in reverse, cockroaches are often found in landfills, as they hitch a ride in the belongings humans have discarded.
The smallest layer of life in a landfill — a “robust set” of microscopic bacteria, fungus, yeast, and protozoa — consumes and digests organic materials in garbage, breaking it down like an enormous compost pile and producing huge amounts of methane gas as a byproduct of their activities.
The concentration of man-made goods, harsh chemicals, and organic waste all rotting together makes for an environment that doesn’t — and can’t — exist anywhere in the natural world. And yet the landfill is teeming with life. Landfills, while ostensibly inhospitable, have become a biological niche, a biome based around humanity’s waste.
