Water is the source of life, the beginning of all life, with it, the earth has become a blue planet with 70% water; With it, the earth becomes alive and vibrant; With it, the emergence of all kinds of life is possible.
Life is inseparable from water. Animals need water, plants need water, we people need water, water is an important part of our human body, in our adult body, water accounts for 70% of body weight, children even reached 80%, drinking more water is more conducive to health and longevity. There have been experiments that have shown that if we are a normal person, with water to drink but without eating, we can barely live for almost a month, but without drinking water, people can not live for a week, which shows the importance of water!
One, for the sake of health and longevity, there is no need for us humans to take the risk of this infection!
In today's society, we have mastered a lot of information about the quality of water, whether the water is soft or hard, what are the hazards, and how to deal with it, and we also know that there are microorganisms, bacteria, parasites, etc. in the water, and these things are all transmitted to us through the medium of water, causing us to be infected and sick!
For this, in fact, we humans have also paid a lot of price! For example, the far-reaching London cholera (a biological disaster caused by the microbial Vibrio cholerae), at first did not notice that it was the water problem, so that London paid a great price and killed many people, and then a John's doctor drew a map of the cholera area, and only then succeeded in finding out the cause of the disease, which was the problem of well water in a place, and finally successfully curbed cholera through the prevention and control of well water! Slowly, as the tragedy caused by these water problems was discovered, it also triggered the water revolution in Europe, and Europeans began to strictly control the safety of water sources, and control domestic and industrial sewage to prevent polluting drinking water! And further treatment of drinking water!
Second, the problem of human water storage! In order to facilitate and cope with drought, in fact, we humans have always had a variety of water storage methods, all kinds of water cellar water towers have come into being, a storage of water may be able to use for a month or even a few months, although this is convenient for us, but stagnant water is easy to breed bacteria, and like water towers are generally sealed and dark, all kinds of microorganisms are easy to multiply, then naturally such water is easy to get sick when drunk directly, and if there are bloodsucking insects in the southern Dongting Lake area (now basically eliminated), uh, It's scary to think about, it's really hard to imagine if you don't chemically treat or boil at high temperature first! In order to live a healthier and longer life, let's deal with it!
1. Animals can't be filtered like people, they can only drink! In fact, I may not be the answer you want, but it is indeed a reason, taking the report of parasitic infection of wild animals in Qinling Mountains as an example, the survey found that the parasite infection rate of giant pandas, crested ibises, takin, and golden snub-nosed monkeys is 100%, and all of them are infected with multiple at the same time! So they can also get infected, but they can only drink it!
Second, animals have a stronger tolerance to habitual habits than humans! The water on the earth is not much, it is said that it is not much, but compared to the animals in a region, it is so much, so whether the water is clean or not, the animals have to drink, so that over time, the animals will produce immunity and antibodies to the microorganisms and parasites in the water in this area, of course, the survival of the fittest will be eliminated if they are not produced in time! However, this immunity is only targeted, and once the water body changes again, it will cause the animal to quickly become uncomfortable and even die!
Third, water in nature is not as dirty as we think! The water of the forest lake, of course, is not only polluted by human beings, although it may seem to be more turbid, sediment and other impurities, there may be fallen leaves, rotten fruits falling in it, animals also bathing in it, there will be some pollution, but in fact, the bacterial infections caused by these pollution are not fatal! Moreover, the animals themselves have a well-developed sense of smell and can tell whether the water is dirty or not!
In short, for us humans, we do not need to take this risk for the sake of universal human health and longevity, and filtered and boiled water greatly reduces the risk of infection by various microorganisms, bacteria and parasites! But animals have no way, they can't change everything around them, they can only choose to constantly adapt, if the living environment is a little better, if it's bad, it's a gamble with their lives every day, the fittest survive, and the unfit are eliminated!
