Pollution

1. Water Pollution

   • The human being is the main cause of water pollution, with industrial waste, which causes the alteration of water by reducing oxygen in its composition due to deforestation, which causes the appearance of sediments and bacteria underground and the consequent contamination of groundwater.
     • What are the effects of water pollution?
       • Desertification
         • The effects of water pollution are also noticeable in the soil. The life that is in it is destroyed, transforming large areas of land that was once productive in deserts where there is no or very little life form.
       • Shortage of drinking water
         • Currently, the leading cause of death is due to the lack of clean water, which forces many to consume unsafe water, killing thousands of people a year.

2. Air Pollution

   • Air pollution occurs when a substance that is introduced by human action into the atmosphere generates a detrimental effect both for people's health and for the environment in general. Among all these substances, perhaps the best known is carbon dioxide, which is produced after the burning of fossil fuels used by cars, airplanes, trains and other means of transport.
     • What are the effects of air pollution?
       • Harm to people
         • Poor air quality has health effects, say many environmentalists. The main respiratory symptoms due to pollution are coughing, wheezing, excessive mucus in the respiratory tract, etc. These symptoms correspond to diseases such as bronchitis, asthma, emphysema, cancer, etc.
       • Environmental damage
         • The most important effect of air pollution is what is known as the “greenhouse effect”, which consists in the fact that polluting gases allow the passage of solar rays that hit the earth while hindering the passage of reflected radiation

3. Land Pollution

   • Pollution of the land involves the alteration of the earth's surface with chemicals that are harmful to life in different ways, endangering ecosystems and also our health.
     • What are the effects of land pollution?
       • Everything we have mentioned above causes changes in the natural structure of the soil. The aforementioned contamination damages the organisms that live in the soil, seriously affecting their development and fertility.
       • Also, when the earth is dead, it turns into a dust that contains toxic pollutants that move through the air with the air, reaching our lungs when we breathe. This also causes chronic diseases and even birth defects.

4. Noise Pollution

   • Noise pollution, noise pollution or noise pollution is the presence of annoying, deafening or constant noise, as well as the simultaneous proliferation of excessive noise in a given area, thus negatively affecting the quality of life of human beings and animals.
     • What are the effects of sound pollution?
       • Sociocusis
         • A slight damage to our auditory system that reveals the appearance of a constant beeping after having subjected it to high sound levels. This effect usually passes with the days, but the abuse of these conditions will lead to the decrease of the hearing capacity.
       • Communicative interference.
         • At higher levels of noise pollution, oral communication becomes more difficult, since our ears cannot discern some sounds from others, but the brain must filter among the number of sounds registered, the one that interests it.
