STOP POLLUTION

What is Pollution?

Pollution, we hear it every other day at school, college and read about it in newspapers. So what is it? Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollutants are the key elements or components of pollution which are generally waste materials of different forms. Pollution disturbs our ecosystem and the balance in the environment. With modernization and development in our lives pollution has reached its peak; giving rise to global warming and human illness.

Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light. Every form of pollution has two sources of occurrence; the point and the non-point sources. The point sources are easy to identify, monitor and control, whereas the non-point sources are hard to control.  Let us discuss the different types of pollutions, their causes and effects on mankind and the environment as a whole.

Types & Causes of Pollution

Air Pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air everyday; these pollute the air.

Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic. The effects of air pollution are evident too. Release of sulphur dioxide and hazardous gases into the air causes global warming and acid rain; which in turn have increased temperatures, erratic rains and droughts worldwide; making it tough for the animals to survive. We breathe in every polluted particle from the air; result is increase in asthma and cancer in the lungs.

Water Pollution has taken toll of all the surviving species of the earth. Almost 60% of the species live in water bodies. It occurs due to several factors; the industrial wastes dumped into the rivers and other water bodies cause an imbalance in the water leading to its severe contamination and death of aquatic species.

Also spraying insecticides, pesticides like DDT on plants pollutes the ground water system and oil spills in the oceans have caused irreparable damage to the water bodies. Eutrophication is another big source; it occurs due to daily activities like washing clothes, utensils near lakes, ponds or rivers; this forces detergents to go into water which blocks sunlight from penetrating, thus reducing oxygen and making it inhabitable.

Water pollution not only harms the aquatic beings but it also contaminates the entire food chain by severely affecting humans dependent on these. Water-borne diseases like cholera, diarrhoea have also increased in all places.

Soil pollution occurs due to incorporation of unwanted chemicals in the soil due to human activities. Use of insecticides and pesticides absorbs the nitrogen compounds from the soil making it unfit for plants to derive nutrition from. Release of industrial waste, mining and deforestation also exploits the soil. Since plants can’t grow properly, they can’t hold the soil and this leads to soil erosion.

Noise pollution is caused when noise which is an unpleasant sound affects our ears and leads to psychological problems like stress, hypertension, hearing impairment, etc. It is caused by machines in industries, loud music, etc

Radioactive pollution is highly dangerous when it occurs. It can occur due to nuclear plant malfunctions, improper nuclear waste disposal, accidents, etc. It causes cancer, infertility, blindness, defects at the time of birth; can sterilise soil and affect air and water.

Thermal/heat pollution is due to the excess heat in the environment creating unwanted changes over long time periods; due to huge number of industrial plants, deforestation and air pollution. It increases the earth’s temperature, causing drastic climatic changes and extinction of wildlife.

Light pollution occurs due to prominent excess illumination of an area. It is largely visible in big cities, on advertising boards and billboards, in sports or entertainment events at the night. In residential areas the lives of the inhabitants is greatly affected by this. It also affects the astronomical observations and activities by making the stars almost invisible.

Effects of Pollution

1. Environment Degradation : Environment is the first casualty for increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like Sulfur dioxide and nitrogen oxide can cause acid rain. Water pollution in terms of Oil spill may lead to death of several wildlife species.

2. Human Health : The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases  that can be causes by air pollution. Water pollution occurs due to contamination of water and may pose skin related problems including skin irritations and rashes. Similarly, Noise pollution leads to hearing loss, stress and sleep disturbance.

3. Global Warming :  The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes. All of them, in direct or indirect way lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.

4. Ozone Layer Depletion: Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released int to the atmosphere which contributed to the depletion of ozone layer.

5. Infertile Land : Due to constant use of insecticides and pesticides, the soil may become infertile. Plants may not be able to grow properly. Various forms of chemicals produced from industrial waste is released into the flowing water which also affects the quality of soil.

Pollution not only affect humans by destroying their respiratory, cardiovascular and neurological systems; it also affects the nature, plants, fruits, vegetables, rivers, ponds, forests, animals, etc, on which they are highly dependent for survival. It is crucial to control pollution as the nature, wildlife and human life are precious gifts to the mankind.

How To Stop Pollution

Life has taken on a very progressive and fast pace – but the bad side is, it is at the expense of the only planet we have. There are a lot of environmental groups, and we even celebrate Earth Day, but we cannot deny the fact that everyday of our lives, we worsen the condition of our environment.

To stop pollution, here are some easy, but effective options:

1. Manage your garbage. Segregate and put litter only into their respective bins. There are still some people who put trash in bodies of water, or sewer systems, or just about everywhere. Clean up your act! Putting litter in its proper place is hygienic, it keeps your place clean and clean-smelling, and it is your responsibility to the community and the world.

2. Recycle. Not recycling has been a ‘habit’ – and a bad habit at that. Always be conscious of what you throw away. Think about its other uses before you forever add another pound of trash to the world. Do not be scared, it is not that hard. You might have just got accustomed to not recycling, that’s why it might look complicated at first, but it isn’t. 

3. Report illegal dumping. You may have noticed a production plant disposing chemicals or garbage near your river or lake—report them. These companies have to be responsible about waste management, and as long as no one is reporting, they will be damaging our environment right under our noses. 

4. Check you car emissions. Maintain the high performance of your car, and you can save the earth from having as many toxins in the air. Use environment-friendly gas, or better yet, walk short distances or use a bike as exercise.

5. Conserve energy. Turn off lights when not in use, use air-conditioning sparsely, and you save not just on electrical bills, but also on carbon emissions from electricity. Climate change is becoming drastic, but we can still use the time we have to turn things around. 

6. Use natural products or environmentally safe products. Decades of used chemicals being dumped into our planet have to stop. Companies who are socially-responsible are now finding ways to use natural and environmentally safe products, and their effects are definitely better than their chemical-based counterparts. 

7. Be an advocate. Influence others to do their share. It’s the same air we breathe, it’s the same water we breathe, and it’s the only planet we have. 

8. Minimalism. Consume only what you need. We live in excess and with too much emphasis on material things. It is important that we use products wisely. This also reduces the amount of waste we generate.

What is important in saving the environment is that we do these things everyday, in every way that we can. These are not things that we should do only for a week, or a month, but these should be practiced daily. The damage in our environment is too great already, so that we cannot just take it in stride.
