It’s proven that many animals possess a sense that make them aware of the earths magnetic field, mice, rats, flies, bees, birds, whales, dolphins, turtles, dogs, deer, cows, snails, foxes, bats, eels and so on, have all been scientifically proven to have ‘magnetoreception’. This magneto sense is a precision instrument like hearing or eyesight and is sensitive to minute variations in magnetism which is why many animals have been shown to be affected by man made magnetism, namely electricity. As Michael Faraday showed us 200 years ago, magnetism is an integral part of electricity. Cows naturally align themselves along the north-south magnetic field as do Roe Deer but both display random alignment when in the vicinity of electricity cables carried by pylons across fields (Burda et al., 2009) see article.
In red foxes it has been proven that interference with the natural magnetic field by humans via electric cables can have a detrimental effect on it’s hunting behaviour. Red fox align themselves in a particular direction before pouncing on rodents underground, they are more successful in a north east direction (Cˇ erveny ́ et al., 2011).
It has also been demonstrated that the reason dogs often spin in circles whilst trying to defecate is because they may not get a good sense the earths natural magnetic field, perhaps because of electromagnetism produced in underground cables. (article)
Radar, has proliferated the natural environment across the globe which produces electromagnetic magnetic waves travelling long distances through the earth, the sea and air. Radar is used in ship navigation, mobile phone, radio and tv, air traffic control, weather monitoring and satellite technology. There are WHO guidelines for it’s safe use in humans (article) but we are less sensitive than birds for example where it has been shown that radar does affect migratory behaviour (article).
The question that arises is to what degree are animals with magneto reception, in the air, on the ground and in the sea, being affected by the electromagnetic noise we humans emit all over the earth? Just because we humans have an almost extinct magneto sense should we not be protecting the depleting wild biomass left on the earth ? (article)
