In New Zealand, there’s a running joke that the sheep outnumber the people. What’s not funny is the consequence of all those woolly creatures: poop. Piles and piles of it. To reduce this overflowing cornucopia of crap, the government is calling in reinforcements in the form of 11 Australian dung beetle species.

The country’s excess poo not only finds it way into water reservoirs, it also releases nitrous oxide into the atmosphere–and to put that in perspective, cow crap alone accounts for 14 percent of New Zealand’s greenhouse gas emissions. “One of the big things basically is the accumulation of dung on pasture surfaces,” Landcare New Zealand research scientist Shaun Forgie told the Australian Broadcasting Corporation. It’s bad for cattle because more dung increases the “zone of repugnance, which means there’s an area around dung which is basically offensive to grazing livestock…. They don’t want to eat around that, so unless you break feed, you’re losing that surface area to graze on.”

Dung beetles cut the crap by feasting on it: adults lay eggs in manure, and the baby beetles feed on the scrumptious scat, devouring an entire pile within 48 hours. Farmers are excited about the project, according to the Australian Broadcasting Corporation:

Despite their energy-saving efforts, wind farms have a bad rap for killing birds. And now there may be a bigger problem: The noise from turbines could be killing livestock as well—or, at least, playing a part in their deaths.

According to one Taiwanese farmer, Kuo Jin-shan, the turbines erected near his farm on an island in the Taiwan Strait have been keeping his goats awake at night. Now that 400 of Huo’s goats have died, he is blaming their deaths on the loud noise coming from the wind farms.

After eight turbines were installed on the Penghu archipelago four years ago, the farmer began to notice some marked changes in his goats—they weren’t as hungry, they were losing weight, and many had started to die.

It seems outlandish to suggest that hundreds of goats dropped dead from sleep deprivation, but local livestock inspector Lu Ming-Tseng has backed up the farmer’s claim. Apparently, unusual sounds can affect an animal’s appetite, disturb how it grows, and make it lose shut-eye, all of which cause serious disruption to the animal’s health.
