"There is regrowth in ecosystems, of that regrowth a species or individual can only take out a small part for themselves, the rest and the predominant part must return to the system to build new regrowth."

Regrowth is perhaps the most important principle on earth. It means that life can go on and thus means that it is the basis for a sustainable existence. Most of it is left as a fertilizer for the benefit of the ecosystem, it is only a part of the interest that a species and way of life can charge for itself. Man is the only species that has violated the law of regrowth. Thus, man threatens both himself and the entire ecosystem as we know it. Man's progress has consisted in plundering the earth's resources and plundering as much as possible for himself. It has now gone so far that humans have depleted virtually all biotopes and subsystems. The oceans have been looted, the forests have been devastated, agriculture has killed the fields and soil biology. Cities and roads occupy areas where there is no natural regrowth at all. They are dead surfaces on the planet.

Can regrowth be measured? Yes, it can be measured. In forestry, the term "quality" is used. It is a measure of how much timber grows in a forest per year. In Sweden, this is between 3 and 7 cubic meters per hectare. The average is 5.3 m3 / hectare. The biomass that grows up is about the same all over the world. At the equator it grows constantly while at the poles it grows intensively for a short period and then a period of plant dormancy occurs. What is crucial for regrowth is solar energy and it is about the same all over the world: 1000 kWh per m2 and year. The difference between the northern and southern temperate regions and the equator is not so great. 1100 kWh for a country like Sweden and up to 1900 kWh for Africa. The biomass that is recreated above the earth is about the same everywhere except at the poles.

How much of the regrowth can humanity take out? Swedish forestry currently takes out about 60% of the regrowth. This is far too much, which is clearly seen in the effects of reduced biodiversity throughout the forest ecosystem. Sweden has no real forest left, it's just plantings. Agriculture takes almost 100% of the regrowth on the cultivation areas. It is unacceptable and the result has been an impoverished field landscape where not so long ago in Sweden there were partridges, quails, barley and grazing animals as well as a plethora of insects, fungi and microorganisms. Today, Swedish agriculture, as in large parts of the world, is a studied devastation and impoverishment of the agricultural landscape. Swedish fields are dead fields with a monoculture that is fed with artificial fertilizer for something to grow. The soil content in the soils is gone and it affects both microorganisms as well as larger mammals. What is produced in the fields is less and less useful to humans. Refined species that are to endure the unreasonable growing conditions give harvests of cereals etc. which are increasingly considered to be dangerous to human health. Wheat is increasingly being touted as a poison by nutritionists. A reasonable limit may not be set exactly, but Station Lunda estimates that a maximum of 10% of the regrowth can be taken out of humanity if we are to maintain an ecosystem that regenerates itself and provides continued opportunities to exploit natural resources instead of plundering them until they end. Does the regrowth principle have any scientific support? In physics, especially thermodynamics, similar system balances prevail. The law of entropy can be interpreted as meaning that the more one tries to maintain an imbalance, the more costly it becomes for the system. Man is just trying to maintain a level of luxury life and plunder of resources that are assumed to be endless. This has the consequence that it becomes increasingly costly to maintain the imbalance. It costs more energy, it burdens ecosystems more through increasing waste and pollution, it depletes the supply of resources on the planet.

It is not growth that man needs, it is regrowth.
