Pollution Volkswagen factory chimneys. Pollution from oil spills. Pollution is any substance or form of energy that can cause some damage or imbalance (irreversible or not) in an ecosystem, physical environment or a living being. It is always a negative alteration of the natural state of the environment, and therefore is generated as a result of human activity. For there to pollution, the pollutant must be in relative amounts sufficient to cause this imbalance. The relative amount can be expressed as the mass of the substance introduced in relation to the mass or volume of the receiving environment of the same. This ratio is called concentration. The pollutants are related to population growth and consumption (fossil fuels, the generation of waste, industrial waste, etc.), since increasing them, the pollution they cause is greater. The pollutants for their consistency, are classified as solids, liquids and gases.Discard those generated by natural processes, since by definition, do not pollute. The agents are composed of solid waste in its various presentations. They cause pollution of soil, air and water. Because microorganisms in the soil and pesticides, the air because it produces bad odors and toxic gases and because the dirty water and not be used. The liquid agents are comprised of sewage, industrial waste, spills of petroleum fuels which damage the water mainly from rivers, lakes, seas and oceans, thus causing the deaths of several species. The gaseous agents are formed by combustion of fuel (nitrogen oxide and sulfur) and by burning fuels such as gasoline (releasing carbon monoxide), garbage and waste plants and animals. All the pollutants come from a particular source and can cause respiratory and digestive diseases. It is necessary for man to become aware of the problem.It’s called air pollution or air pollution to the presence in the environment of any agent (physical, chemical or biological) or a combination of several agents in places such forms and concentrations that are or may be injurious to health, safety or for the welfare of the population, or may be harmful to plant or animal life, or prevent the normal use of the property and places of recreation and enjoyment of them. Environmental pollution is also incorporated into the receiving bodies of solid, liquid or gaseous or mixtures thereof, provided that adversely alter the natural conditions of the same or which may affect health, hygiene or welfare of the public. The Blacksmith Institute, an NGO that monitors pollution, made a list of the most polluted places in the world, it contains the following countries: Azerbaijan, China, India, Russia, Ukraine and Zambia.
