Animals and Ecosystem Validity of Nature laws (Negative Retroaction-Genetic Feedback 1) ” Every action carried out by nature can’t be done in a shorter way with the same means”. (Leonardo Da Vinci[1]). Let’s imagine a huge and perfect machine the gears of which are all connected one another, the movement of the smallest of them influences all the others. Similarly, in nature, all living things but also elements (air, water, soil, rains, gases….) happen to be linked one another through interaction relations the study of which was called with the word ecology.

The trans-species jump from the animal reserve (second part) MICROBIOLOGIC CONSEQUENCES OF HUMAN CIVILIZATION Another example how man’s action can influence the spreading of epidemics is given to us by the history of the Spanish conquest of the Americas. When we think of such an enterprise, we are usually convinced it was possible only thanks to the military superiority of the old world inhabitants compared with the Aztecs and the Incas. This theory is true if we consider the Spaniards, besides their guns, brought, unconsciously, those that are called bacteriological weapons according to the modern terminology.
Vital revolution and overpopulation Beginning from 1798, the year in which Edward Jenner published his results about vaccination against smallpox, a series of scientific victories over contagious diseases has taken place. Between 1877 and 1879 Louis Pasteur discovered the bacillus of corbuncle; in 1882 and 1883 Robert Koch the ones of tuberculosis and cholera.
Plague Epidemics From a certain moment on, that is about 40,000 B.C., our ancestor, who, now, has evolved in Homo Sapiens-Sapiens, leaves the African equatorial forest and spread about everywhere on the planet except for the Antarctic zone.
