There is no denying the unwanted consequences of car emissions, burning of fossil fuels, chemical effluent, and other pollutants. Their negative effects include the increasing incidence of respiratory, skin, and heart conditions. But 'environments' consist of more than just the elements of air, earth, and water. Whilst it is quite right to headline the damage we are doing to our lungs and other bodily organs, it must not be thought that this is the only way in which we are polluting our world. The effects of artificial light and constant noise are also detrimental to mental and physical wellbeing. Many people, to their cost, rarely see the stars in the night sky, or experience the quiet of the natural environment in which our species evolved.
