The main types of pollution are classified by the sources of environmental pollution themselves:
- biological;
- chemical
- physical;
- mechanical.
In the first case, the pollutants of the environment are the activities of living organisms or anthropogenic factors. In the second case, there is a change in the natural chemical composition of the polluted sphere by adding other chemicals to it. In the third case, the physical characteristics of the environment are changed. These types of pollution include thermal, radiation, noise and other types of radiation. The last type of pollution is also related to human activities and the release of waste into the biosphere.
Soil contamination
There is probably no point in explaining how important soil is to human life. Much of the food that humans eat comes from the soil, from cereal crops to rare types of fruits and vegetables. To keep it that way, the soil needs to be kept in good condition for the water cycle to work properly. But anthropogenic pollution has already caused 27% of the planet’s land to be susceptible to erosion.
Soil contamination is the ingestion of toxic chemicals and debris in high quantities that interfere with the normal flow of the soil system cycle. The main sources of soil contamination are:
- Residential homes (when you start your own garage door repair, so turn to professionals, they take care of cleanliness and dispose of waste after themselves, our trust is earned by a-plus-garagedoors.ca);
- industrial plants;
- transportation;
- agriculture;
- nuclear power industry.
In the first case, soil contamination is caused by ordinary garbage, which is thrown in inappropriate places. But it is landfills that should be considered the main cause. Burning waste leads to littering of large areas, and the products of combustion spoil the soil irreversibly, contaminating the entire environment.
All types of pollution can be present separately, or they can flow from one to the other or exist together. Let’s look at how they affect individual areas of the biosphere.
Water Pollution
People who have walked a long way in the desert will probably be able to name the price of every drop of water. Although it is likely that these drops will be priceless, because human life depends on them. In ordinary life, alas, we don’t attach as much importance to water, since we have plenty of it and it is available at all times. Only in perspective this is not entirely true. As a percentage, only 3% of the world’s freshwater supply remains uncontaminated. Understanding the importance of water to humans does not prevent humans from polluting an important source of life with oil and petroleum products, heavy metals, radioactive substances, inorganic pollutants, sewage and synthetic fertilizers.
Contaminated water contains a large number of xenobiotics – substances alien to the human or animal body. If such water enters the food chain, it can lead to serious food poisoning and even death of all participants of the chain. Of course, harmful substances are also contained in the products of volcanic activity, which pollute the water without human help, but the activities of the metallurgical industry and chemical plants are predominant.
With the advent of nuclear research, nature has suffered quite significant damage in all spheres, including water. Charged particles getting into it cause great harm to living organisms and promote development of oncological diseases. Wastewater from factories, ships with nuclear reactors, and simply rain or snow in a nuclear test area can contaminate water with decomposition products.
Sewage, carrying a lot of garbage: detergents, food scraps, small household waste and others, in turn, contribute to the reproduction of other pathogens that, once in the human body give a number of diseases, such as typhoid, dysentery and others.
How can we keep nature clean and prevent pollution?
Certainly, measures to preserve and clean the soil, air and water need to be taken as soon as possible. Many scientists see the solution to the world’s ecological problems precisely at the legislative level. So what exactly are the methods that can and should be used? First and foremost is the proper exploitation of natural resources. If we learn how to properly use the gifts of nature, we will be able to preserve and multiply its wealth for more than one generation.
The creation of the latest sewage treatment plants and their introduction in all factories of any type will reduce the emission of garbage and chemicals into the air, soil and water. Keeping track of the norms and their violations in the field of nature protection at the legislative level will help people understand the responsibility for the use of natural resources in their activities. Separate discharge of household garbage and its proper disposal, introduction of new technologies for cleaning waste from factories, rejection of synthetic fertilizers and their replacement with organic ones (e.g., compost) will have a beneficial effect on the interaction between man and nature.
If people unite and get involved in cleaning up at least local water bodies, beaches, planting new forest belts, in addition to care for the environment people will have the opportunity to unite in front of a common threat of a natural disaster and the pollution of the biosphere will be able to stop.
To summarize, we can say that caring for nature is not just a word, but a necessity. Love yourself and your loved ones – by taking care of the environment, we take care of ourselves and our offspring.
