AIR POLLUTION: A GLOBAL CRISIS

Pollution is defined as the presence or introduction into the environment of substances or contaminants that cause harm or discomfort to living organisms or disrupt the natural balance of the environment. These hazardous materials are referred to as pollutants. Pollutants may be naturally occurring, such as volcanic ash. They can also be caused by human activity, such as factory runoff or trash. Pollutants have a negative imparity of the air, water, and land.

Natural events such as volcanic eruptions and wildfires, as well as human activities such as reindustrialization, transportation, and agriculture, can all contribute to it. Pollution is a major environmental problem that has serious implications for human health, the economy, and the natural world. Environmental protection and the well-being of all living organisms require efforts to reduce pollution and promote sustainably practices.

There are numerous items that harm the environment but are valuable to people. Exhaust pipes from cars release pollutants. The environment is contaminated when coal is used to produce power. The land and water are polluted by waste and act on the sewage from homes and businesses. Pesticides are chemical poisons that are used to eliminate weeds and insects, but they also taint streams and put wildlife in danger. All living species, including blue whales and single-celled bacteria, depend on the air and water that the Earth provides. All life forms are in danger when these resources are compromised.

One international problem is pollution. Pollution can travel to remote areas where no one lives, despite the fact that metropolitan areas normally have higher pollution levels than rural ones. For instance, scientists have found chemicals and pesticides in the Antarctic ice sheet. In the middle of the northern Pacific Ocean, there is a large accumulation of microscopic plastic debris known as the Great Pacific Garbage Patch. Pollution is carried by air and water currents. Marine contaminants are dispersed widely by ocean currents and migrating fish. Radioactive material that has been unintentionally released from a nuclear reactor can be picked up by winds and dispersed globally. A factory's smoke travels across international borders.

Pollution can take many different forms, including air, water, soil, noise, and light pollution.

Air Pollution

A known risk to environmental health is air pollution. We recognise what we are seeing when a brown haze forms over a metropolis, exhaust billows across a busy highway, or a plume rises from a smokestack. Although some air pollution is not visible, you can smell it and be warned.

It seriously jeopardises the well-being and prosperity of the entire world. Around 6.5 million people worldwide die from air pollution each year, a number that has increased over the past 20 years. Air pollution refers to any physical, chemical, or biological change in the air. Plants, animals, and people are all adversely affected by air pollution from toxic gases, dust, and smoke.

A specific proportion of gases are present in the atmosphere. It is dangerous to survive if the composition of these gases changes. The earth's temperature has increased, a phenomenon is known as global warming, as a result of this imbalance in the composition of the gaseous atmosphere. In many nations around the world, air pollution is a major problem. The World Health Organization (WHO) defines air pollution as the release of pollutants into the atmosphere that are harmful to both individual humans and the environment as a whole.

In the world, air pollution causes close to seven million fatalities annually. Currently, nine out of ten people breathe air that contains more contaminants than the WHO's recommended levels, with those in low- and middle-income nations suffering the most.

Types of air Pollution-Air pollution can be categorized into several types based on the characteristics of the pollutants, their sources, and their effects on human health and the environment. The following are some of the major types of air pollution-

1. Primary Pollutants:

The primary pollutants responsible for air pollution are the ones that directly cause air pollution. Primary pollutants enter the air directly. Some are released by natural processes, like ash from volcanoes.

Most are released by human activities-

Carbon oxides are released when fossil fuels burn.
Nitrogen oxides form when nitrogen and oxygen combine at high temperatures. This occurs in hot exhausts from vehicles, factories, and power plants.
Sulphur oxides are produced when sulphur and oxygen combine. This happens when coal that contains sulphur burns.
Toxic heavy metals include mercury and lead. Mercury comes from smokestacks. Both metals have industrial uses.
Volatile organic compounds (VOCs) are carbon compounds, such as methane. VOCs are released by many human activities. Raising livestock, for example, produces a lot of methane.
Particulates are solid particles. These particles may be ash, dust, or even animal wastes. Many are released when fossil fuels burn.

2. Secondary Pollutants:

Secondary pollutants are formed as a result of the intermixing or intermingling of primary pollutants. Smog, a combination of fog and smoke, is a secondary pollutant. This type of smog appears as a brown haze in the air. Photochemical smog occurs when certain pollutants undergo a chemical reaction in the presence of sunlight. Ozone is the primary component of photochemical smog (O3). Ozone near the ground is a pollutant. This ozone is harmful to humans and other living things. However, ozone in the stratosphere shields Earth from the Sun's harmful ultraviolet radiation.

CAUSES OF AIR POLLUTION

Some of the common causes of air pollution include:

The Burning of Fossil Fuels - The majority of air pollution is caused by incomplete combustion of fossil fuels. These include coal, oil, and gasoline, which are used to generate energy for electricity or transportation. The amount of CO released at a high level indicates the amount of fossil fuel burned. This also releases other toxic pollutants into the atmosphere, such as nitrogen oxides. Inhaling polluted air caused by the combustion of natural gas and fossil fuel reduces the heart's ability to pump enough oxygen. As a result, various respiratory and cardiovascular illnesses can occur. Furthermore, nitrogen oxides are to blame for acid rain and smog formation. When fossil fuels are burned, they emit more than just CO2.
Transportation - Transportation is one of the leading causes of air pollution, accounting for about 28% of global greenhouse gas emissions. Cars, buses, trucks, and other vehicles emit pollutants such as carbon monoxide, nitrogen oxides, and particulate matter, which contribute to poor air quality. Traffic congestion and the use of outdated and inefficient vehicles exacerbate the problem, especially in densely populated urban areas.
Industrial Activities - Manufacturing, mining, and power generation are all major sources of pollution in the environment. These activities produce significant amounts of carbon dioxide, sulphur dioxide, nitrogen oxides, and particulate matter, all of which are harmful to the environment and human health.
Agricultural practices - Agricultural practices, such as livestock farming and crop burning, are also significant sources of air pollution. Livestock farming produces methane, a potent greenhouse gas, and ammonia, which can cause respiratory problems. Crop burning releases particulate matter and other pollutants into the air, contributing to poor air quality.
Natural causes - Natural causes of air pollution include wildfires, dust storms, and volcanic eruptions. These events can release large amounts of particulate matter and other pollutants into the atmosphere, affecting air quality and human health. However, these events are relatively infrequent and do not contribute significantly to long-term air pollution.
Residential activities - Cooking, heating, and lighting are all examples of domestic activities that contribute to air pollution. When solid fuels such as wood, charcoal, and coal are burned for cooking and heating, particulate matter, carbon monoxide, and other pollutants are released into the atmosphere. Indoor air pollution, caused by inadequate ventilation and the use of indoor pollutants, contributes to poor air quality and can have serious health consequences.
Open Burning of Garbage Waste - Open burning of garbage is much more harmful to your health and the environment than one may think. As per Engage EPW, Delhi Air Pollution is choking public health Delhi generates a whopping 9500 tons of waste every day, which makes it India’s second waste dumping city. Exposure to open burning of garbage waste can pose serious health risks including Cancer, Liver issues, Impairment of the immune system, and reduced reproductive functions, can also affect the developing nervous system.

EFFECTS OF AIR POLLUTION:

The effects of air pollution can be devastating to human health, the environment, and the economy. Here are some of the main effects of air pollution:

Respiratory and Cardiovascular Diseases: Air pollution can cause a variety of respiratory and cardiovascular diseases, including asthma, bronchitis, and lung cancer. It can also increase the risk of cardiovascular disease, stroke, and other problems.
Environmental Degradation: Plants, animals, and ecosystems can all be harmed by air pollution. It can cause acid rain, which harms soil and water bodies and slows crop and forest growth.
Climate Change: Air pollution contributes to climate change by releasing greenhouse gases like carbon dioxide, methane, and nitrous oxide. These gases trap heat in the atmosphere, leading to global warming, melting ice caps, and rising sea levels.
Economic Costs: Air pollution can also have a significant economic impact. It can cause structural damage, reduce agricultural productivity, and raise healthcare costs.
Social Injustice: Air pollution often disproportionately affects low-income communities and people of colour, who are more likely to live near industrial areas or highways. This can lead to a range of health and environmental injustices, including higher rates of asthma and other respiratory illnesses.

Impact of air pollution on human health:

Air pollution has a significant impact on human health. Here are some of the key ways in which air pollution affects human health -

Air pollution can cause respiratory issues like asthma, chronic obstructive pulmonary disease (COPD), and lung cancer. Particulate matter (PM) and ground-level ozone are both significant contributors to respiratory issues.
Cardiovascular Problems/Cardiovascular issues: Air pollution can also lead to cardiovascular issues like heart attacks and strokes. Air pollution's fine particulate matter can enter the bloodstream and cause inflammation, leading to the development of cardiovascular problems.
Neurological Problems: Air pollution has been linked to neurological issues such as Alzheimer's disease and Parkinson's disease. Air pollution's fine particulate matter can enter the brain and cause inflammation, which can damage brain cells and lead to neurological problems.
Reproductive problems: Air pollution has been linked to reproductive issues such as low birth weight, premature birth, and stillbirth. Air pollution exposure during pregnancy can also cause developmental problems in the fetus.
Other health issues: Air pollution has been linked to a variety of other health issues, including cancer, diabetes, and obesity.

In short, we can say that the air pollution has a significant impact on human health, causing respiratory, cardiovascular, neurological, and reproductive issues, among others. As a result, it is critical to take action to reduce air pollution and protect human health.

Prevention:

Some important measures that can be adopted by individuals to contribute towards the prevention of air pollution have been listed below.

Usage of public transport and carpooling: Individuals can reduce the amount of pollutants released into the atmosphere and cause less air pollution by reducing the amount of fuel combusted for their transportation needs. Furthermore, these options are cost-effective and can help you save money.
Switching off the lights when they’re not in use: The majority of our electricity is generated through the combustion of fossil fuels, which contribute significantly to air pollution. As a result, conserving electricity is an effective method of reducing air pollution.
Reusing and recycling products: Reusing products (that can be reused) saves the energy required to manufacture another one of those products. Furthermore, recycling products consume less energy than manufacturing new ones.
Avoiding the burning of garbage and smoking: The burning of garbage contributes significantly to air pollution. Cigarette smoking is another source of air pollution. Avoiding these activities and raising awareness about their negative consequences can go a long way towards preventing air pollution.
Avoiding the use of firecrackers: Firecrackers are generally used to celebrate certain occasions. However, they are known to cause severe air pollution and are, therefore, extremely harmful to the environment. Personally avoiding the use of firecrackers and spreading awareness about their negative consequences is a great way to help prevent air pollution.

If we don't act now to save the planet from air pollution, the consequences could be severe and long-lasting. Here are some of the potential impacts:

Health consequences: Air pollution can have serious health consequences for humans, including respiratory and cardiovascular problems, neurological problems, and reproductive problems. If we don't take action to reduce air pollution, these health problems will continue to worsen, leading to increased illness and premature death.
Environmental damage: Air pollution also damages the environment, harming plant and animal life, and disrupting ecosystems. This can lead to reduced biodiversity, food insecurity, and other environmental problems.
Climate change: Air pollution contributes to climate change, which is already causing severe weather events, rising sea levels, and other environmental problems. If we don't take action to reduce air pollution, the impacts of climate change will continue to worsen, leading to more severe and frequent natural disasters and other problems.
Economic consequences: Air pollution also has significant economic consequences, including lost productivity, healthcare costs, and damage to infrastructure. If we don't take action to reduce air pollution, these economic consequences will continue to mount, leading to reduced economic growth and increased economic instability.

If we do not act now to save the planet from air pollution, the consequences could be severe and long-term, including serious health issues, environmental damage, climate change, and economic consequences. As a result, taking action to reduce air pollution and protect human health, the environment, and the economy is critical.

Conclusion – Air Pollution

The high time has arrived when the problem of air pollution needs to be discussed on a bigger platform.

Even international conventions like United Nations Organization are also giving its focused on the pollution problem. That is why various steps are also being taken by the people on a global scale. We all should take part in this movement to keep our earth clean with utmost cleanliness. Only then a good life could be lived on this earth. If this air pollution is not limited by today it can prove very dangerous in the coming time when people will suffer from taking breath even.

Air pollution is one of the major environmental problems that need to be solved simultaneously. Urbanization has led to the exploitation of natural resources, which has led to constant pollution in the atmosphere. Effect of all pollution is harmful and to protect the environment, we have to plant more and more trees.

Air pollution is a huge problem not only in India but the whole world, various organizations do their bit to make sure that plans are made to restrict air pollution, but unfortunately, those plans never get executed rightly. That is why even after knowing that the air is getting polluted every day, the organizations around the world are unable to provide a good solution to it. As human beings, we must contribute, that is why, we need to gather and make sure that all the places, suffering from air pollution, should get organized in a manner so that air pollution should not exist. Everyone should participate in schemes like Swachh Bharat Abhiyan which will not only reduce the air pollution in the country but will also reduce various other kinds of pollution.

We all have a responsibility to ensure that we use better practices to reduce air pollution. If we don’t take any action, both our survival and that of our generations are greatly threatened. If each one of us takes the necessary steps, we will all be on the way to a cleaner, fresher continent. Change starts with you and me.
