The first reason: the difficulty of capture is different. Most carnivores are birds of prey, such as strong lions, ferocious tigers, bloodthirsty wolves, leopards, etc. Most of them are very ferocious and it is difficult for human ancestors to hunt them. However, herbivores are generally not so aggressive, especially some birds, which naturally become a great choice for humans. The second reason is related to the energy transfer in the ecosystem. The efficiency of energy transfer between different trophic levels is only 10-20%, that is, at least 1-20,000 kilograms of cattle and sheep are needed to feed 2,000 kilograms of wolves and tigers. This is reflected in hunting, that is, there are many more herbivores than carnivores in nature, and it is easier for people to find herbivores and kill them. Third, herbivores are easier to raise. After gradual evolution, humans began to choose domestication to solve the meat source problem. At this time, the poultry domesticated by humans must be the kind of animals that will not grab food resources from themselves. At this point, herbivores are the best choice. Because the earth in primitive society is really densely forested and densely covered with vegetation, people can use it to raise some herbivores, so it is easier to feed on their meat. Fourth, it involves the quality and taste of the meat. In order to hunt, carnivores often exercise, their body fat is mostly not high, and their meat is old and woody. However, herbivores have high fat content and taste good. From the perspective of energy supply, high-fat herbivores are also preferred. In addition, carnivores mostly eat raw meat, and the content of parasites and bacteria is much higher than that of herbivores. It is definitely not a good choice for people who eat raw meat. In addition, the meat of carnivores has a high content of purine, which is somewhat acidic and tastes bad. Therefore, as humans evolved into modern times, they developed the habit of eating more herbivores and less carnivores. This proposition is actually a false proposition. After all, humans eat carnivores, and the number of such animals they eat is quite large. Among the invertebrates eaten by humans, carnivores include: octopus, squid, cuttlefish, jellyfish, etc.; Carnivores among the fish eaten by humans include: black carp, mandarin fish, sea bass, black fish, h fish, eel, catfish, sturgeon, river eel, pike, stonefish, sea bass, hairtail, grouper, mackerel, tuna, salmon, cichlid, conger eel, flounder, etc. Among the amphibians eaten by humans, carnivores include frogs, stone frogs, bullfrogs, wood frogs, tiger frogs, giant salamanders (farmed), etc. Among the reptiles eaten by humans, carnivores include: soft-shell turtles, some venomous and non-venomous snakes (farmed), crocodiles (farmed), etc.; Carnivorous mammals eaten by humans include: dogs (farmed meat dogs). |
