Plastic gears running against plastic gears wear down over time because of friction and that creates dust. I have seen some retro modding solutions to this problem that add lubricant to the gear box to significantly reduce friction and wear.

UPS has a good union. It is usually the same driver on the same route and they know what they're doing. I don't know what happened with FedEx and their union but it always seems to be a different driver who is not confident. For residential service anyway. Amazon pits multiple local 3rd party carriers against each other in a race to the bottom in both quality of service and labor quality of life. Really shameful behavior by Bezos IMHO.

"We find irrigation of cattle-feed crops to be the greatest consumer of river water in the western United States, implicating beef and dairy consumption as the leading driver of water shortages and fish imperilment in the region. We assess opportunities for alleviating water scarcity by reducing cattle-feed production, finding that temporary, rotational fallowing of irrigated feed crops can markedly reduce water shortage risks and improve ecological sustainability. Long-term water security and river ecosystem health will ultimately require Americans to consume less beef that depends on irrigated feed crops."
