What is pollution? In recent years, the use of the word pollution is so widespread that it is often used as a synonym for dirty environment. Pollution, on the other hand, consists in the direct or indirect introduction into an environment of substances, or even energy, capable of transforming natural balances and produce negative effects on health. Some of these transformations are irreversible in medium or long terms. There are several types of pollution: air pollution is mainly caused by industries that expand fumes and by cars that produce exhaust from engines. The effect is smog, or dirty fog. Air pollution is also the cause of the ozone hole and the greenhouse effect. The life of all living beings depends on the availability of water on the planet. Water is becoming an increasingly precious good. Water pollution depends on the introduction of liquid waste coming both from the sewer system and from industrial waste, of pesticide substances and chemical fertilizers and from the introduction of oil. Like water and air, the soil is obviously affected by human interventions and his activities. The presence of pollutants have altered its natural balance. The dispersion and accumulation of solid waste is the prevailing form of soil pollution. The most dangerous waste comes from hospitals and industrial wastes. Lots of industrial companies produce waste and residues from their processing in illegal landfills instead of treating them or having them treated. How can we do to decrease the death rate due to this phenomenon?Many environmentalists argue that the exploitation of gasoline and electric power cars is the main cause of contamination and therefore the use of electric cars, bicycles and solar panels could help to live a better, healthy life.
