One of the Library's missions is to preserve audio-visual materials. Much of this work happens at the National Audio-Visual Conservation Center in Virginia. Here's a quick look at the process of digitizing a 78 RPM disc, making it more accessible for Library patrons like you! pic.twitter.com/hhzBq6MDH7

One of the missions of the Library of Congress of the United States is to digitize information sources to preserve them from loss and make them more broadly available. In this video, a professional conservationist takes a 78 RPM record from 1908 and prepares it for recording. He cleans the record, mounts it precisely on a turntable, and chooses the right stylus for this recording.
The song is "Don't Take Me Home" by Eddie Morton. It's a novelty song about a man who prefers incarceration to living with his shrewish wife.

Years later, I found myself at another station that actually had a wax/vinyl disc cutter in the equipment storage room. It was from the days when that was the only way to record ads, direct to wax. I'm sure anything recorded there was quite wavy and distorted.
The M is for Man-eating.
Lisa: But isn't that a bit short-sighted? What happens when we're
overrun by lizards?
Skinner: No problem. We simply release wave after wave of Chinese
needle snakes. They'll wipe out the lizards.
Lisa: But aren't the snakes even worse?
Skinner: Yes, but we're prepared for that. We've lined up a fabulous
type of gorilla that thrives on snake meat.
Lisa: But then we're stuck with gorillas!
Skinner: No, that's the beautiful part. When wintertime rolls around,
the gorillas simply freeze to death.
When a new species is introduced to an area, it can often make an easy living. Organisms that are not a problem in the area in which they evolved can overrun the natives when they find themselves in new locations. They have an easy time of it, squeeze out native species, and breed like crazy.
Eventually however, the presence of these invaders who become so plentiful becomes an opportunity for another species, one that preys on the invader. The predator might itself be an introduced species, or it might be an existing organism that has adapted and stepped up to the task/free lunch offered by the invasive species.
Yes, over time, these things have a way of working themselves out. But the span of time required can be longer that is convenient for human activities. And certainly much diversity is lost along the way.
Humans have been responsible for the introduction of so many organisms into new locations. Sometimes it is intentional, like the cane toads. Sometimes introductions are a by-product of other activities such as Eurasian plants brought to the Americas as seed in animal fodder or larval stages of marine organisms in ballast tanks.
In most cases, we've lost diversity, a lot of diversity. The case of the cane toads is a rare one in that people pay attention to it. They don't so much notice the difference in the assemblage of weeds in roadside ditches, or the loss of native bee species.
It's a pity. Sadly it is rather inevitable.
