Man has started to use the knowledge and control of reproduction processes in livestock farming. Since the fifties of the 20th century, intensive farming by artificial insemination has increased considerably. At the same time, the number of cancer diseases is on the rise and is nowadays prime cause of chronic diseases and premature death in the elderly.

The pig used to be kept as a food reserve for the cold winter months. Hams and sausages etc. We have started to eat more meat without fruit and vegetables.The theme of "artificial reproduction in mammals for increasing meat production" has never been brought before. Making livestock farming more sustainable is certainly not going to work to prevent global warming and the loss of plant and animal species. To make this book not only a message of doom I do proposals for more plant based food and for energy transition in the form of chemical production of hydrogen for fuel cells. What does energy transition have to do with the damaging consequences of greatly increased meat production? Farmers can repurpose their stalls with a power plant for heat and LED lighting. Strawberries, mushrooms, peppers, lettuce, grapes and pineapples can now also be produced in winter. With local production with a greater supply and diversity, the supply of fruit and vegetables over the equator will decrease.
