Plants are the great intermediaries by which the elements in rocks, converted by microorganisms into humus , can be made available to animals and man, to be built into flesh, blood and bone. Chemical fertilizers on the contrary, can neither add to the humus content of soil nor replace it , They destroy its physical properties and therefore its life.
Plants that are chemically fertilized may look lush, but lush growth produces watery tissues, which become more susceptible to diseases and protein quality suffers.
In studies it was found that many of the killer diseases have developed only within last hundred years, demonstrably through toxic chemicals introduced into environment and food supply.
As a byproduct in 1st world war, to keep fleas , lice and other insects from contaminating GI Troops , the most toxic pollutant ever invented was DDT . Dye firms , banding together for patriotism and for profit , produced explosives, chemical fertilizers, drugs and as a bonus, the poison gases responsible for some 8,00,000 casualties in World War 1.
One of the first to sense that the use of chemical fertilizers was doing more harm than good , that it was destroying the life and vitality topsoil , momentarily stimulating plant growth but actually inviting diseases was Sir Albert Howard (a British colonial officer in India). He proved that livestock fed on organically grown fodder were disease resistance, as were his oxen, which even during an epidemic of hoof and mouth disease rubbed noses with infected neighboring stock with no ill effects.
During late 60s the World Bank applied pressure on India to allow western chemical companies to built fertilizer plants in subcontinent. Collusion is indicated by the fact that farmers received subsidies from the govt of 10-20% on fertilizers and 25% on pesticides, plus govt backed loans to pay for them. As a result fertilizer consumption in India rose between 1969 and 1979 from 2.5 to 50 kg per ha.
Italian scientist Amigo Mosca , winner of the chemistry prize at Brussels World Fair presented certain findings. He stressed that the point that toxic farm chemicals are radiomimetic in that they ape the character of radiation. The damage resulting from nuclear radiation is same as damage resulting from the use of toxic genetic chemicals and the use of fungicides of organic syntheses (zineb, captan, phaltan etc) annually causes same damage to present and future generations as atomic fallout from 29 H Bombs of 14 megatons, damage equal to the fallout of 14500 atomic bombs of the Hiroshima types.
Healthy and economic alternatives do exist, though some of them appear extraordinary.
Today soils are tired, overworked, depleted, sick , poisoned by synthetic chemicals . Hence quality of food is suffered so as the health.
