The production of food, the healthy life of plants and animals are linked to cyclical phenomena related to three facts related to the axis of rotation and two facts derived from the translation of the earth.

The knowledge of these five basic cyclical facts seems to have been forgotten by a society immersed in immediacy and linearity and as well as by some scientists who, instead of starting their investigations from a natural fact, start them with a prefabricated conclusion thus achieving immediacy in the explanation of a fact.

The three facts related to the Earth’s axis are:

• The north-south axis presents an inclination of 23Âş27′ with respect to the vertical
• The terrestrial axis also presents an oscillatory movement, called nutation movement, recovering its position every 18.6 years.
• The terrestrial axis also presents a movement, called the precession of the equinoxes, which has a cycle of 25,767 years called the great year.

For its part, the two facts derived from the translation of the earth are:

(a) The translation around the sun that lasts 365.24 days of terrestrial rotation

(b) But since the earth follows the sun on its journey around the center of the galaxy, it cyclically returns to its position every 225 million years.

This period is called the galactic year.

These different cycles that overlap each other originate a great variety of cyclical phenomena on the surface of the planet: tides, marine thermohaline current movement, Coriolis effect in the atmosphere, annual alternation of the seasons, alternation of great ice ages, appearance of forests and desertification, all of them with a great impact on food production and on the life of plants and animals.

If science will adopt the cyclical view of many natural phenomena, instead of immediacy and linearity, global plans could be established, based on model simulations, that would improve food production and living conditions for plants and animals.

In Veterinaria Digital we propose to change the paradigm “a yes, a no, a straight line and an objective” for the paradigm “the development of life is based on the alternation of cycles and the balance between opposites”.
