@Yulianna Birds are known to be sensitive to magnetic radiation. Increasing number of cell phone towers in cities apparently are bringing down bird population. The microwaves (300 MHz to 300 GHz) emitted by cell phone towers and handsets has been found to be responsible for damaging eggs and embryos of sparrows

@KiwiBird Sparrow became extinct in a few countries locally. They were reintroduced from different countries but so far, the objectives of the govt have not been able to meet.

@Yulianna It is an established fact in a few regions that just after introduction of cell-phones in the city, viewing of sparrow became very rare. In recent past it is slowly coming back, possibly due to acclimatisation.

Electromagnetic hypersensitivity intolerance syndrome (EHS) has been recognised by WHO in 2014 where by patients feel serious headache and nausea in Wi-fi or such EMR saturated area. Some 5% of US citizen suffer from this syndrome to a various degree. Even a number of patients have shifted to a RF free zone in Arizona where a number of Radio Telescope are installed for space research.

Cell radio frequency also induce Colony Collapse Syndrome in Butterfly. (A research paper of XXXXX University)

Advent of cell-towers is the major reason behind extinction of sparrows in cities apart from other environmental degradation .

@Yulianna which opens up a whole can of worms... How do you define intelligence ...i don't think people can agree on that yet

@ozgirl512 throw the worms away and wear the can...
