The pollution It is often related to human action and activities, however, natural events, such as volcanism, can also cause it. There are different types of pollution, such as atmospheric, aquatic, soil, sound or acoustic and visual. This type of pollution can be very harmful to living beings, including humans, who can develop health problems as a consequence of the degradation of the environment. environment.
Natural and anthropogenic
The pollution It is a modification of the nature which negatively affects humans and also other forms of life found in that place. The pollution It is usually caused by humans and their activities. A good example is the release of pollutants that occurs: when fossil fuels are burned, when pesticides are used in agriculture or macro farms.
However, it is worth noting that the pollution It is not always caused by humanity. Volcanoes, for example, are a natural source of pollution. Since when they erupt they release a large amount of toxic gases and particles into the atmosphere and surroundings.
Types of pollution
Atmospheric
It consists of the release of substances that affect the composition of the air. The burning of fossil fuels, for example, can lead to the release of various substances into the air. The particles, the carbon dioxide o CO2, NOx and sulfur dioxide are some of the known air pollutants.
The pollution of the air can trigger serious problems for our body, increasing the incidence of problems such as asthma, lung cancer and chronic obstructive pulmonary disease. According to the WHO, air pollution kills about seven million people worldwide each year.
Aquatic
It is caused by substances that come into contact with the aquatic environment, causing changes in its nature. The release of raw sewage, oil spills, and dumping of mercury into water are some of the situations that cause water pollution.
The pollution of water can cause the death of the organisms that live there. But it is also capable of causing diseases in humans who feed on these living beings. since many polluting agents are bioaccumulative. In addition, they cause economic impacts, harming fishing and tourism, for example. It can make affected ecosystems disappear.
From the soils
It affects the superficial layer of the Earth’s crust. Pesticides used in agriculture are an example of substances that can cause this type of disease. pollution. Improper disposal of garbage, such as waste deposited in landfills, can also cause soil pollution. This is terrible for everyone, since we depend on agriculture to feed ourselves. But it also kills fauna and flora.
Acoustic or sound
It is the one that implies excess noise. These noises can be caused by traffic, machines, musical shows and parties, for example. This excess can trigger stress, difficulty concentrating, headaches, insomnia and hearing problems. It has the same or worse effect on animals.
Visual
It is characterized by excessive communication visual in a certain place. Excessive signs, billboards, banners and advertisements can cause visual pollution. This affects the visual appearance of the cities, overshadowing, for example, the historical beauties of the place. But it is also disastrous for biodiversity, For example, for migratory birds it can be lethal, since it makes them lose their way.
This variety has significant negative impacts on humans. In addition to the visual discomfort caused by excess information, the large number of signs and billboards, for example, can be responsible for traffic accidents because they distract drivers.
