If indeed silence is golden, it is also becoming as rare as gold. It seems that the progress of man includes a rising volume of noise. In every home a stereo or television will fill the rooms with sound. Between sunrise and sunset, streets and highways are a constant source of noise from cars, buses, and trucks. You can pass any factory or construction area and the roar of its machinery will make your ears ring. Music is played in every supermarket, most restaurants and many offices.

Big cities of the world such as Los Angeles (California, USA), Osaka (Japan) are well-known for their noisiness.

Noise pollution is the new side effect of our technological age. Day or night, the sound of work fills the air. It seems that the soothing effects of silence are nowhere to be found. Even the quiet of our carefully protected wilderness areas can be invaded at any moment by passing jet.

We are realizing, finally, that silence is a natural resource and must be protected by law.

Scientists have discovered an unexpected reason for climatic change: airplanes. New research has revealed that vapour trails from jet aircraft flying across the country make nights up to 1⁰С (1.8⁰F) warmer, and days 1⁰С cooler. The study was conducted by checking the records at 4,000 weather stations when aircrafts were grounded across the US in the aftermath of the September 11 attacks. When compared with historical averages, they discovered that those nights were colder and the days warmer, with the temperature difference between night and day rising by an average of 1.8⁰C. The vapour trails, which can turn into high altitude cirrus clouds in the right conditions, reflect sunlight back during the day reducing air temperature at ground level and act as an insulating layer at night helping keep warm air in.
