The exposure to the low level of EM fields consequent to widespread use of the internet, radiosatellites and radar equipments leads to increased endosymbiotic archaeal growth. Climate change can lead to extremophilic endosymbiotic archaeal growth and neanderthalisation of the species. There is increase in endosymbiotic and colonic archaeal growth. The increase in colonic archaeal growth leads to breaching of the blood-gut barrier and archaeal endosymbiosis. The colonic archaea also generates RNA viroids which are converted to DNA viroids by colonic epithelial HERV reverse transcriptase and gets integrated into the colonic genome. The RNA and DNA viroids hybridise with the viroidal and bacterial population of the gut microbiome and virobiome DNA and RNA of the gut leading to generation of new emerging viruses like COVID 19.
