The fall of the sparrow


March 20th is the world sparrow day. Looking back on the disappearing numbers of the sparrows and explaining the connect between EMF Radiation (wireless/cell tower radiation) and the falling number of sparrows. 


A survey of sparrow population in 2010 in coastal Kerala (India), one of the greenest states in India, states that the number of sparrows in the state has gone down by 80%.
Sparrow numbers have fallen by 60% in London and they are practically non-existant in the city.
Spain registered a 70% fall in the number of house sparrows between 1998-2008.
Jawaharlal Nehru University (JNU) school of life-sciences estimates 50% fall in sparrow population in India. It also states the severity of fall in Andhra Pradesh, where the sparrow population has gine down by 80%.
In 2002, the sparrows was included by the IUCN in its Red Data List of threatened species along side snow leopard, tiger and red panda.

Like dogs, sparrows are known to be synanthropic — they have a ecological dependence on humans. Domestic sparrow populations in cities are estimated to have fallen by 75% in the last 23 years (1994-2017). This coincides with emergence of wireless technology and telecommunication. However, air pollution, lack of nesting grounds, fall in the numbers of feed (small insects), absence of green cover and proliferation of wireless technologies are disrupting the small lives of these chirpy merry-makers – pushing them to extinction (Refer to the seminal work by Alfonso Balmori and Enrique Murgui)

We list down the key factors linking proliferation wireless radiation and the fall in sparrow numbers.

1. Navigation skills of the birds and the earth magnetic systems are correlated. These induce large distance migrations and return, or short distance localized flights. However, interposing another magnetic grid over the earth’s magnetic grid (such as the one that wireless telecommunication towers create) risks the navigation skills of these birds and lead them astray from their colonies.

2. Till the turn of the century, sparrows have monopolized roof tops as their breedng and nesting grounds. This, however was disrupted by telecom towers in the last 2 decades.Long-term exposure to EMF Radiation at close ranges has damaging effects on the nervous system and immune system of sparrows.

3. Sparrows have thin exo-skeletons. Therefore the effect of medium power wireless radiation on their bodies is significantly higher. Especially because these birds co-habit the same roof tops with the mobile masts. Continuous exposure to EMF radiation affects the nervous system and navigational skills making them incapable for navigation and foraging.

4. Nesting grounds built in close proximity of roof towers result in delayed egg hatching or increased unhatching due to the radiation effect. Consider the fertilized egg to have been slow micro-waved to death.

5. Prolonged exposure to microwave radiation reduce the activity level in the sparrows making them less alert and more vulnerable to attacks by predators.

6. Other factors directly contributing to the fall of sparrows are killing of garden insects through garden pesticides (diet of the sparrow), fall in the number of green spaces and open grass lands, avian-unfriendly architecture, reduction in vegetation spaces which act as breeding grounds, air pollution and increase in lead concentration.

Sparrows are considered to be the advance bio-indicators of climate and environmental changes for the urban eco-system indirectly and fore-warning human health risks. We can site Butterflies and Bees as more of such species which are loosing out to the relentless onslaught of unmindful and unsustainable development. These species are important – because they act as pollinators – and their fall precipitates the fall of green – which then falls a vicious spiral reducing the numbers of the bees, butterflies and sparrows even further.

End lines: Brightsandz is not anti-technology. We ourselves promote the use of technology – but it has to be done in a sustainable manner – so that the immediate use of technology and its ensuing benefits is not offset by a long term unsustainability and fall-out.
