POLLUTION

Pollution is an alteration of the environment that can be of a natural type, as an eruption, or of an anthropic type, that is due to man. Pollution can be electromagnetic and acoustic.

ELECTROMAGNETIC POLLUTION:

Electromagnetic pollution is caused by the use of phones, radio and television tools (as x-rays). Science does not know of the consequences that the presence of these magnetic waves could generate and that can compromise human health, because they radiate harmful emissions.

  NOISE POLLUTION:

Noise is the main element of noise pollution. Levels of 50-60 decibels (a normal conversation) are only annoying. The 60-65 decibels could result in physical suffering. The 65 decibels could lead to hearing problems. From 85 decibels (in the case of discos) permanent injuries. Continuously listening to a noise could lead to breathing or heart problems and headaches.
