<span>The turning point is, that during the Neolithic age, most societies started to turn from hunter/gahterers into farmers and animal herders. They did not more around a lot any more. Groups became larger, flat hierarchies changed into complex ones.</span>

Read through this article titled "These Tiny Plastic-Munching Caterpillars Can Clean Up Our World - But There's A Catch"

A species of caterpillar may provide answers on how to best eradicate plastic waste. Plastic waste is currently a 300 million-tons-per-year problem.

Researchers discovered the waxworm in 2017. It is seemingly able to eat through common types of plastic, including polyethylene. Polyethylene is a non-biodegradable type of plastic. It is the most commonly used plastic worldwide.

"They are voracious feeders during these larval stages," Bryan Cassone told USA TODAY. Cassone is an associate professor of biology at Brandon University.

Now researchers have offered an explanation. A study was published on March 3 in the open peer-reviewed journal Proceedings of the Royal Society B. It found that the micro-organisms in the wax worm's gut help them consume and metabolize plastics.

Researchers at Brandon University in Manitoba, Canada, found that waxworms are able to "ingest and metabolize polyethylene at unprecedented rates." This is thanks to the micro-organisms in their intestines.

"The caterpillar's gut microbiota seem to play a key role in the polyethylene biodegradation process," the researchers wrote.

Researchers found a greater amount of "microbial abundance" in the caterpillars' guts when they were ingesting plastic than when they ate a traditional diet of honeycomb.

In waxworms, polyethylene metabolizes into a glycol. Glycol is biodegradable.

Waxworms are not an end-all solution to plastic waste, however. Wax larvae are pests for bees. They naturally feed off honeycomb and run the risk of reducing their populations. In turn, they risk reducing populations of plants and crops.

Further, it remains unclear how the plastic breakdown process works in the waxworm. It is also unclear how its health is affected by its consumption.

The hope, Cassone said, is that researchers can harness what in the gut bacteria helps caterpillars so easily break down plastic. That way it can be used to design better ways to eliminate plastic from the environment.

"We envision harnessing the waxworm and its microbiome to develop approaches that do not require whole organisms – rather the products or by-products produced from their interactions that make their ability to break down plastic so efficient," Cassone said.

What impact do you think this example of "muckraking" had on americans?
Rudik [331]
I think the impact that "muckracking" had on Americans was this:

Due to the mishaps and the loss of trust that some Americans may have for their own, state, county, or even government that used some points of "muckracking" to begin. The best examples of "muckracking" in history can be accountable in today's day in age of the 21st Century. Now, for the most recent events on the other hands we could go on about lists and lists about things such as Donald Trump and Stormy Daniels and so on and so forth (But we won't talk about those begin again, this is only meant to answer your question, not bring up another :D but then again, we all differ from opinion) Now back to the point- I think that the best common examples of "muckracking' in today's society would be through celebrities and politicians. Many of the paparazzi try to capture celebrity photos, but also grab their opinions about things, but then twist and divert the story in a whole other way. But the same goes for politicians except using a different method. Anyways this is my opinion on how I see "muckracking" and how it has impacted Americans.


I hope my opinion and answer to your question was able to clear up some things. If you have any more questions about this or need another opinion on it- or if you simply just have another question that you would like to have answered, please check out my profile and I will be happy to do so. Again, I hope this was helpful to you, have a wonderful day! :)
