Human hair ruined the dove
What could be better than feeding pigeons in the park on a warm spring? But, have you noticed that most pigeons are missing one or two toes? The same goes for a group of pigeons that a group of French researchers are concerned about. How is this going? It’s all because of human hair.
The place where pigeons gather is often the place where humans gather, and the hair that humans shed will entangle on the toes of pigeons. The wings of pigeons are particularly unsuitable for unraveling fibers that are several millimeters long, so they will become tighter and tighter until the toes die, fall off, and heal.
Chicken poop causes a fire
In June 2019, all of Europe, especially Spain, suffered a heat wave.
The advantage of heat waves is that it can make things dry quickly, but the disadvantage is that dry things (such as a lot of Spanish chicken poop) can easily catch fire. With the help of warm air and dry wind, the fire spread quickly. Soon, about 40 square kilometers of land was covered by dense smoke.
This alone has made the incident known as “the worst wildfire in Catalonia in the past 20 years.” Fortunately, only 53 people need to be evacuated, but they need 350 firefighters, dozens of fire trucks and water vehicles, 7 planes, two seaplanes and heavy machinery. This is the first time in the history of Spain’s National Meteorological Service that it has issued a “red” alert due to a heat wave, all because of a pile of chicken shit.
99% of vultures are killed by medicated livestock
For a long time, the vultures of India flew happily. The world’s second largest animal husbandry allows them to feast on fresh carcasses, and they actually have no natural enemies. But they soon began to die, millions of lands. 99% of vultures disappeared like this, no one knows why.
Later, scientists discovered that an anti-inflammatory drug called “Diclofenac” is often used to feed livestock. It is used by people as a panacea, if animals show any symptoms of discomfort, people will give them to eat. If you don’t eat feed, give them diclofenac; if you feel weak, eat more diclofenac; if you can’t sleep, you can also take diclofenac. It turns out that vultures that eat animal carcasses containing this drug will get gout, which is fatal to them.
The matter is not over yet. Another group of scavengers-wild dogs filled this nauseating gap. As the dominant local religion prohibits killing dogs, the number of wild dogs in some parts of India has increased by 1,200%. As a result, rabies cases have also increased. The number of rabies cases in India now accounts for 1/3 of the total number of rabies cases in the world.
Landfill changed the behavior of animals
Humans have been working hard to dispose of garbage. Of course, putting a huge amount of waste in an invisible place does not mean that other creatures will not notice.
The most prominent example is the baboon community in Kenya. There, the dominant male baboons are usually not as strong as in Disneyland until a tourist resort starts to pour leftovers into the jungle, which leads to vicious competition within the baboon group. They competed every day until a piece of spoiled meat infected them with tuberculosis, which effectively eliminated all the violent male baboons in this population. Under the action of large doses of sedatives, the remaining male baboons recovered quiet. The tension disappeared, and since then, the newcomers and the young baboons who grew up in the new environment have been extremely peaceful. The impact of that incident lasted for decades in this group.
The melting of the Arctic releases dormant diseases
The 6 most terrifying words you can say to environmentalists are “The Arctic is melting”, but the following is “This is not just ice”. The vast northern grasslands and tundra of Siberia and its surroundings are covered by a thick layer of permafrost, which preserves a variety of prehistoric and modern “Easter eggs”.
Let’s start with cold prehistoric creatures: with the help of low temperature, their bodies are almost intact, but the warm climate means that they can finally freely decompose and release all the carbon elements buried in the ground for a long time in nature. This is very bad (we are talking about 150 billion tons of carbon). These specimens contain pathogens and bacteria that may cause the reappearance of diseases that we think have been extinct or under control. In 2016, a 12-year-old Siberian boy died of anthrax, and dozens of people in his village were sick. Experts sent to the area traced the pathogen back to a caribou carcass 75 years ago. It was trapped under permafrost for decades until the heat wave in the summer exposed its carcass and the infectious bacteria Released into water and soil, and then into the local food supply chain. This also resulted in the death of 2,300 reindeer.
So, what diseases are still lurking in these cold corpses? Some people worry that it could be anything, from Spanish flu to smallpox to the Black Death. In fact, people did find traces of Spanish flu in animal carcasses in Alaska. In another chilling study in France, a 30,000-year-old virus was resurrected after being heated and analyzed.
