Only half a century ago the bull runner went to the farms with the bull to fertilize the cows.Since the fifties of the 20th century, intensive breeding in livestock has increased sharply. The increase in meat products and dairy production could only be acheived with artificial insemination of mammals and the animals unilaterally fattening with soy flour, corn and fish meal. The unbridled breeding of animals, through artificial insemination of cattle and with incubators for poultry, has a devastating effect on our health, nature and the climate. Fast food, unnatural food and meat consumption lead to obesity, vitamin deficiencies, chronic diseases and premature death. In many countries cancer is now the main cause of premature death. Successive pandemics with highly pathogenic influenza aviary or coronaviruses from the meat industry will cause increased mortality and bring mankind to the brink of collapse.
