Geobiology is a term used to describe a study of the effects of the Earth's radiation i.e. telluric currents and other electromagentic fields upon biological life e.g. human, animal and plant. Also described thus, 'Geobiology is the study of the Earth's influence, at a precise point, on everything that lives, be it human, animal or plant'. The term is derived from Ancient Greek gē meaning ‘earth’ and βίος; meaning ‘life’ Practitioners of geobiology will typically use a dowsing rod, pendulum or their hands to ascertain the location of radiation and then use this information to make an assessment on its effect on a residential dwelling or workplace and upon localised natural life. Practitioners may also claim be to able to propitiously locate and model a building on a similar basis to the theories of Feng shui, Vastu Shastra or use of Sacred geometry Within this pseudoscience, Hartmann Lines and Curry Lines are identified as forming grid patterns on the Earth's surface and posited on occasion to have negative effect on health and viability of biological life. Other patterns of Earth radiation named after practitioners include Peyré lines , Romani waves , Benker cube and Wittmann lines, the latter being an alternative name for the radiation named after Curry Underground flowing water deemed to create radiation caused by the friction of water against mineral deposits is considered to have a similar effect to the grids mentioned above. Geological faults and the consequent difference in electric charge of the mass each side of the fault is seen as generating radiation which may have an adverse effect on the habitat. Also practitioners may claim to locate cosmo-telluric chimneys suggested to be a vortices of energy reaching up into the Cosmos from the Earth As well the phenomena mentioned above, considered inherent to the natural environment, a practitioner of Geobiology may also seek out radiation derived from human activity. Examples of this being overhead and underground power lines and telecommunication infrastructure.
