Pollution: How Do We Protect Our Environment?


Introduction of pollution.  

Pollution occurs when the environment is contaminated by harmful substances and material. Essentially, it’s anything thing can harm the surrounding environment. There are different kinds of pollution like air pollution, water pollution, land pollution, etc. Pollution comes from different sources and is harmful to both humans and the planet. Therefore, the environment. In this blog I will discuss pollution and how to get rid of it.

What is Pollutants?

Pollutants are chemicals that cause significant change in the environment. They may take the shape of either light, heat, or chemical compounds. Pollutants are emission agents that are produced either spontaneously or from a man-made source. Such toxins affect the soil, air, and water. Pollution is divided into the contamination of the purpose source and non-point source.

Human Made Pollutants

Everyday products used by people everyday have become major sources of pollution. Pollution is a global problem. However, it is a bigger problem in urban areas. Pollution can spread in isolated areas like the Atlantic Ice Sheet. 

Approximately 200 million people are exposed to toxic pollution, in areas where there are high levels of pollution. In these areas, a lot of children are born with birth defects. In addition, people in these area tend to have a lower life expectancy. They are also more likely to suffer from diseases like cancer.

 Problems caused by pollution

 There are different types of pollution and with each type comes different problems.

Problems caused by air pollution:  

Health problems caused by humans:

  • illnesses like pneumonia or bronchitis
  • itching and headaches in humans with exposure.
  • heart disease, lung cancer or cause damage to other organs like kidney or liver.
Contamination of ecosystems:
  • Air pollution particles can accumulate on different bodies like lakes and rivers and contaminate them.
Environmental Effects

Acid rain: Sulfur Dioxide and Nitrogen Oxide accumulate in the atmosphere and cause acid rain. These chemicals arise from the burning of different fuels and hence are a result of air pollution.

Global Warming

One of the major agents in global warming is natural and anthropogenic air pollution. This happens due to the release of Carbon Dioxide, methane nitrous oxide. Problems caused by water pollution(Destruction of aquatic flora and fauna). Water pollution causes damage to many water bodies which makes aquatic flora and fauna most susceptible to its effects.

Contamination of drinking water: In Urban areas, Industrial effluents have contaminated most of the water bodies near human settlement which puts the health of its people at risk as drinking contaminated water causes liver damage and causes diseases. According to a report, up to 2.1 billion people around the world don’t have access to safe drinking water which makes up for almost ¼th of the world’s population do not have access to safe drinking water.

Disturbance in the food chain: Due to the presence of tiny microplastics and industrial effluents in different water bodies, this causesmicroorganisms to ingest them and when larger animals consume these beings, pollution moves up the food chain.  Problems caused by land pollution.

Pollution of soil: this causes loss of fertile lands and land erosion which can cause much greater losses.  

Global Warming

One of the most severe and possibly a long-lasting problem is global warming. The main agent in Global Warming is pollution. It is caused by a sort of blanket of pollution which traps heat in the Earth’s atmosphere. This blanket is formed by Greenhouse gases which are emitted from several useful objects for humans like cars, trains, air conditioners, etc. These greenhouse gases get accumulated in the upper levels of the Earth’s atmosphere and trap heat coming from the Sun which ultimately leads to the rise in Earth’s temperature.

Global Warming is such an important issue because of the greater troubles arising from it like melting of Polar Ice Caps, Extinction, and endangerment of many species, loss of habitats and many more troubles which have gruesome effects on the pla net and will become worse by the day if solutions are not found and worked upon. (National Geographic, 2019).

Evidence of pollution

Pollutants will be created by human action, like trash from the factories or it is often natural, like volcanic ash which damages the standard of air, water, and land. pollution causes many diseases and health issues. The long-run and short-term exposures to fine particle pollution also referred to as fine particulate (PM2.5) results in the premature death and harmful respiratory effects, like asthma attacks and affects the vascular system, including heart attacks and strokes. In 2009, the EPA (Environmental Protection Agency) determined that emission of greenhouse emission (CO2) and other greenhouses gases cause severe health problems, global climate change, and acidification of the ocean.

According to the Air Quality Guidelines and also the Global Update in 2005, both the short term and long-run exposure to PM2.5 suggest additional health outcomes be related to PM2.5. Among them, the foremost findings thus far are (i) the consequences of short term exposure to PM2.5 ends up in cardiovascular mortality and morbidity; (ii) several new health outcomes including atherosclerosis; (iii) adverse birth outcomes and childhood respiratory disease; (iv) neurodevelopment and cognitive function additionally as other chronic disease conditions like diabetes.

WHO unit, which is composed of scientists in epidemiology, toxicology, and public health, provided evidence that pollution caused by chemicals (organic or inorganic products like detergents or petroleum products), pathogens (coliform bacteria) and other physical parameters (e.g. Elevated water temperatures decrease oxygen levels) lead to serious health issues.

Water

Pollution is the exposure of contaminants in bodies of water like oceans, lakes, rivers, and groundwater which result in the degradation of aquatic ecosystems and cause public health problems (water-borne diseases) for people living downstream.

Domestic sewage is the primary source of coliforms and other organic pollutants that cause water-borne diseases and endangers the standard of water within the water bodies, where high oxygen levels are required to survive for fish and other aquatic organisms.Land pollution is the accumulation of hazardous or non-hazardous waste materials which can be solid or liquid onto land or underground which contaminate the soil and spring water.

Pollutants

The pollutants that cause pollution are classified into municipal solid waste (MSW), construction and demolition (C&D) waste, and unsafe waste (e.g. from septic tanks). MSW includes nonhazardous garbage and trash from homes (food wastes e.g., meat and vegetable scraps) and dry materials like paper, glass, textiles, and plastic objects and ponderous waste materials like discarded mattresses, appliances, pieces of furniture), institutions (e.g., schools), commercial, and industrial facilities. (Britannica, 2018) C&D waste includes concrete rubble, wood and metal objects, and other inert materials produced when structures are built, renovated, or demolished.

Hazardous wastes include solids, sludges, or gases by various chemical manufacturing companies, petroleum refineries, paper mills, smelters, machine shops, dry cleaners, automobile repair shops, and plenty of other industries or commercial facilities. once they contact soils contaminated chemically (e.g. gasoline, benzene), people have serious health issues like cancer (e.g. leukemia), damage of the system nervous and neuromuscular blockade, and depression of the central system caused by the presence of lead (Pb) in soil (Britannica,2018).

Future of Pollution

On the off chance that contamination goes on in this pattern, at that point the accompanying occasions can occur.  Eradication: Pollution adversary affects untamed life and will keep on doing so into what’s to come. A 2004 report in “New Scientist” expresses that contamination is the essential driver of the elimination of different types of butterflies and different bugs in Great Britain (live science,2018). Even though contamination represents a danger to animals ashore, sea-going animals may confront a significantly more serious risk. As indicated by the Environmental Protection Agency, an expected one to 11 percent of all marine species will fall into elimination consistentlysomewhere in the range of 1975 and 2015.

Water Contamination

Water contamination comes from modern and agrarian spillover and can cause problems for oceanic life. contamination of our water also impacts people. It affects us because we are dependent on oceanic life for sustenance.

Human Illness: As poison levels increase, human exposure to poisons will increase too. The Environmental Protection Agency found that toxins cause both malignancy and coronary illness.

Air Contamination

Air contamination is a major issue in metropolitan areas because there are a lot of vehicles. These vehicles produce toxins that are detrimental to humans’ health.

As air contamination expands, specialists envision that the negative wellbeing impacts of openness will likewise increment. An Earth-wide temperature boost: Burning petroleum derivatives for energy, for example, coal, oil, and flammable gas discharges carbon dioxide and different poisons into the Earth’s air. High carbon dioxide levels increment the air’s temperature. As indicated by the John Ray Initiative, this can make the Earth’s normal the temperature quickly changes. The expression “nursery impact” regularly has negative implications. Be that as it may, the nursery impact is characteristic and advantageous cycle by which the Earth’s ozone keeps heat from getting away into the air. Since carbon dioxide makes the temperature on Earth increment, the ozone layer’s capacity to trap heat near the surface can bring about a dangerous atmospheric deviation as contamination levels heighten.

Financial Effects:

Because of its capacity to cause disease in people, it can significantly affect the world’s economy. In fact, the World Health Organization noted that an expanded pace of disease caused by a contaminated environment can put a monetary strain on insurance agencies, government-financed wellbeing projects, and people themselves.

Furthermore, the more people who become sick, the less profitable representatives are available to play out the exercises important to keep a business running. Understudies missing from school because of diseases brought about by contamination may botch instructive chances they would have in any case delighted in – further expanding the future monetary difficulties social orders would look like because of contamination.

  Effects of pollution

Pollution can affect many aspects of our lives. We can not see it. However,we are exposed to it everyday. For example, we burn fossil fuel everyday, but we can’t not see it.

Additionally, the toxins which are wrecking the air and expanding the amount of greenhouse emission is extremely risky for people. An expanded degree of dioxide will prompt an unnatural weather change. Without water, humans can not exist. Therefore, we must find a way to reduce the amount of contaminants in our environment.

In addition to pollution in the water and air, pollution from waste products contaminate the earth and turns poisonous for living things . On the off chance that land contamination continues occurring like this, we cannot have ripe soil to develop our yields on.

Solutions

It is our responsibility as humans to reduce the amount of contaminants in our environment.

Ways To Reduce Pollution
  • Use public transport instead of our vehicles for reducing the amount of pollutants in the air. Don’t use plastic bags.
  • Recycle and reuse things.
  • Avoid burning materials. This will be possible if we use solar, wind, geothermal energies instead of fossil fuels.
  • Reduce the use of electronics like the conditioner, refrigerators.
  • Don’t pour fats, medicines, oils, grease down the sink to prevent water pollution.
  • Use only phosphate-free soaps and detergents.
  • Properly treat factory waste before releasing them into the environment.
  • Use biodegradable and organic products.
  • Pollution may cause different types of health problems and diseases in humans. So, we must protect our environment.
