Consequences of pollution

  1.                  Refuse can cover the surface of the water and make it hard or impossible for aquatic plants to grow, destroying aquatic habitats. 
  2. When waste is dumped into bodies of water, ducks, fish, turtles, and birds can choke, suffocate, and die. 
  3. Chemicals like insecticides, pesticides, paint, motor oil, etc. can poison aquatic life People and animals on land can get sick or die if they eat diseased fish or drink dirty water. 
  4. Excess nutrients can cause algal blooms. Algae sink to the bottom when they die. As they break down, they take oxygen out of the water. Low levels of dissolved oxygen in the water make it impossible for fish and other aquatic organisms to live there.

Effects of Pollution

  1. Environment Degradation: When air or water pollution goes up, the environment is the first thing to suffer. When the amount of CO2 in the air goes up, it causes smog, which can block the sun from getting to the earth. So, it stops plants from making food through photosynthesis. Acid rain can be caused by gases like sulphur dioxide and nitrogen oxide. Several kinds of wildlife could die because of an oil spill that pollutes the water.
  2. Human Health: When the air quality gets worse, it can cause asthma or lung cancer, among other things. Some of the diseases that air pollution can lead to are chest pain, a stuffy nose, a sore throat, heart disease, and lung disease. Water pollution happens when water gets dirty, and it can lead to skin problems like rashes and irritations. In the same way, noise pollution can cause loss of hearing, stress, and trouble sleeping.
  3. Global warming:  The release of greenhouse gases, especially CO2, is causing the Earth to get warmer. Every other day, new businesses open, new cars hit the streets, and trees are cut down to make room for new homes. All of them increase CO2 in the environment in some way, either directly or indirectly. The rise in CO2 makes the polar ice caps melt, which raises the sea level and puts people who live near the coast in danger.
  4. Ozone Layer Depletion: Ultraviolet rays can’t reach the earth because of a thin shield called the ozone layer. This shield is high in the sky. Because of what people did, chemicals like chlorofluorocarbons (CFCs) were put into the air, which caused the ozone layer to get thinner or depleted
  5. Infertile Land: If insecticides and pesticides are used all the time, the soil may stop being able to grow plants. Plants might not grow as they should. Chemicals made from industrial waste are dumped into running water, which also hurts the quality of the soil.
  6. Industries: As was said above, industries have been polluting the environment, especially since the beginning of the industrial revolution. This is mostly because more fossil fuels are being used. Coal was used to speed up machines in the 19th century and for a large part of the 20th century, taking the place of people. Pollution from factories mostly affects the air, but it can also affect the soil and water. This is especially true for industries that make power, like plants that make electricity.
  7. Transportation: Since people stopped using animals to travel around, pollution has gotten worse and worse. Up until now, it has only gotten worse. Like pollution from factories, most pollution from transportation is caused by fossil fuels. In fact, people moved on from horse-drawn carriages to cars, trains (which used to run on coal before electricity), and aeroplanes. As the amount of traffic grows every day, so does pollution.
  8. Agricultural Activities: Most of the pollution of water and soil comes from agriculture. This is because more pesticides are being used and because it is grown in a very intensive way. Almost all pesticides are made of chemicals and are used to keep diseases and animals that could harm crops away from them. When you try to keep these types of life at bay, you almost always end up harming the environment.
  9. Trading Activities: The production and exchange of goods and services are part of trading. When it comes to goods, most pollution is caused by packaging or transportation. Packaging often uses plastic, which is made from fossil fuels.
  10. Last but not least, pollution is produced in residential areas. First, homes can’t be built without destroying the natural environment in some way. Wildlife and plants are driven away, and buildings and roads take their place. The construction itself is also a source of pollution because it requires the work of industries. Then, when people move in, they will make waste every day, some of which the environment can’t handle yet without being devastated.
  11. Environmental Pollution’s Effects on Humans: Pollution in the environment has mostly physical effects on people, but in the long run, it can cause problems with the brain. The most common respiratory problems are allergies, asthma, irritation of the eyes and nose, and other types of respiratory infections. Especially when air pollution is high in cities, like when it’s hot, these well-known diseases can be seen. On top of that, it has been shown that pollution in the environment is a major cause of cancer. This can happen, for example, when we eat chemicals that were used to make processed foods or pesticides that were used on crops. Some of the less common diseases are hepatitis, typhoid, diarrhoea, and changes in hormones.
  12. Effects on Animals: Pollution in the environment mostly hurt animals by making their living environment unsafe for them to live in. Acid rain can change the chemical makeup of rivers and seas, making them dangerous for fish. A large amount of ozone in the lower atmosphere can make it hard for all animals to breathe. Nitrogen and phosphates in the water will make toxic algae grow too much, which will stop other kinds of life from going about their normal ways of life.  Soil pollution will hurt and sometimes kill microorganisms in the long run. This can kill the first parts of the primary food chain, which is a very terrible thing.
  13. Effects on Plants: Acid rains can kill plants, especially trees, and this will also hurt animals because their natural environments will change. Ozone in the lower atmosphere can stop plants from breathing, and harmful pollutants can be taken in through water or soil.
  14. Effects on the Ecosystem: environmental pollution, which is almost always caused by human actions, hurt the ecosystem by destroying important layers and making the upper layers even worse.

Pollution not only destroys lives by trying to destroy their respiratory, cardiovascular, and nervous systems, but it also hurts nature, including plants, fruits, vegetables, rivers, ponds, forests, animals, etc., on which they depend a lot for survival. Controlling pollution is very important because nature, wildlife, and human life are all precious gifts to humanity.

How to Control Pollution

The following are ways we can prevent pollution:

  1.                 Materials that would otherwise be thrown away can be recycled, which means that they are processed and used again. This is better than putting them in dumps, which pollute the soil or burning them in incinerators, which pollute the air. Broken glass, paper, plastic, steel, aluminium, and other things can all be recycled.
  2.                By planting more trees, we can cut down on the amount of carbon (IV) oxide that factories and cars put into the air. This is because carbon (IV) oxide can be used by young plants to make wood. Carbon (IV) oxide is one of the greenhouse gases that cause global warming, which is when the earth’s atmosphere gets warmer. The less carbon (IV) oxide there is in the air, the more plants grow.
  3.                  Instead of putting sewage in water bodies, it can be turned into manure.

A Global Attempt at Pollution Control

Even though man-made chemicals have made life better around the world, they have also put people’s and animals’ health at risk. Late in 2000, the United Nations Environment Program held a meeting to write a treaty that would limit the production and use of twelve persistent organic pollutants (POPs), especially those used as pesticides. This was done to try to control the effects of toxic global pollutants. Environmentalists have called these twelve toxic chemicals the “dirty dozen.” They include eight pesticides (aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, mirex, and toxaphene), two types of industrial chemicals (hexachlorobenzene and polychlorinated biphenyls, or PCBs), and two types of industrial byproducts (dioxins and furans). Not because they are the most dangerous, but because they are the ones that have been studied the most. DDT was given a special exemption because it is still used a lot in Africa to stop malaria. It can be used in those countries until new chemicals or strategies can be made and put into place. The United States was one of the 122 countries that signed the treaty. But before it can go into effect, at least fifty of these countries must also ratify it.

Possible Future Approaches to Cleaning Up Pollution

Cleaning up tens of thousands of toxic sites on factory grounds, farms, and military bases are going to cost a lot of money. In the U.S., this amount could soon be more than $700 billion. So far, the main way to deal with polluting chemicals has been to dig them up and take them to a dump. But after 10 years of research, scientists at the start of the 21st century found that hundreds of plant species and the fungi and bacteria that live around their roots look for and often break down chemical molecules that are harmful to most other life. For example, there are sunflowers that absorb uranium, ferns that thrive on arsenic, clovers that eat oil, and poplar trees that break down dry-cleaning solvents. There is still a lot to learn about using plants as pollution sponges, but early reports that they helped clean up pollution were encouraging.
