Environmental Problems, Causes, and Solutions
Environmental Problems-Write an essay on environmental problems, causes, and solutions – Pollution is the cause of every human problem. Environment pollution is due to the defects produced in natural equilibrium due to the penetration of pollutants in the environment. It means pollution which has adverse effects on human life. Types of environmental pollution – ‘contaminated with unwanted substances such as air, water, soil’, which directly affect the organism and other indirect effects harm the ecosystem.
This creates adverse effects on the biological world, called pollution. Human development process and modernity are an important contributor to environmental pollution. Even the normal activities of humans are called pollution, from which negative results are obtained. For example, nitrogen oxide pollutants produced by the industry. Although its elements are not pollutants. It is the energy of sunlight which transforms it into a mixture of smoke and fog.
1-Balance of Environmental Problems- On this earth plants and animals live with a complex relationship. This is a relic that exists between them and their environment. Carbohydrates are the main source of energy for humans, plants and animals. But only plants can produce them with atmospheric carbon dioxide and water in the presence of sunlight. In this process, they release oxygen. Animals depend on plants or other animals for the supply of carbohydrate. Humans and animals use atmospheric oxygen to burn carbohydrates to meet the energy required for their activities. And, they leave carbon dioxide. Thus in our environment, there remains a microscopic balance between oxygen and carbon dioxide.
2-Environment Pollution-The faster and more comfortable means of transport-steam, diesel, and electric locomotives; petrol or diesel-run cars, buses or trucks-all pollute the air. Remember, thermal power plants produce electricity. Chemical fertilizers pollute the earth and as a result our agricultural produce. Excessive use of pumps drawing underground water for irrigation has resulted in lowering the water table. As governments subsidize chemical fertilizers and give free power to pumps, they are being used to increase production.
Industrial development, of the chemical industry, pollutes not only air but also water in the rivers making their water undrinkable. As a result, there is a crisis of potable water.
3. How is Environment Polluted?-The faster and more comfortable means of transport-steam, diesel, and electric locomotives; petrol or diesel-run cars, buses or trucks-pollute the air. Remember, electricity produces by thermal power plants. There are various types of pollutions depending upon surroundings -air, water, soil, sound, etc. These are:
1 Air pollution: When polluters. smoke, dust, poisonous gases, etc. pollute the atmospheric air I know it as air pollution.
2. water pollution: When polluters industrial wastage, acid rain, chemicals etc. pollute the river, pond, lakes, sea etc. then known as water pollution.
3. Soil pollution,- acid rain, chemical manure, industrial wastage etc. pollute the soil, land etc. we know as soil pollution.
4. Sound pollution-loudspeaker, TV, transistors, the sound of aeroplanes and vehicles causes excess noise known as sound pollution.
5. Causes of Pollution: There are various causes which create pollution. These are as follows,
1.effects of air pollution- Smoke produced from different vehicles like-buses, cars, trucks, etc. and from the factories causes air pollution.
2 Due to the incomplete combustion of woods, Coals, a poisonous gas carbon mono ‘ oxide and carbon dioxide produces which also causes air pollution.
3. Due to the incomplete combustion of a fuel like -petrol, Diesel etc. in vehicles produces lead and smoke causes air pollution.
4. Wastage materials like slag coming out from factories mix in soil, river, sea, ponds, lakes etc. and causes water and soil pollution.
5. Chemical manure like -urea, phosphate etc. causes soil and water pollution.
6. Acid rain causes soil and water pollution. 7. Noise from loudspeakers, buses, cars, T. V, transistors, aeroplanes etc. causes sound pollution.
5.The solution for pollution: There are various measures to control pollution. These are as follows:

The Environmental Balance-On this earth plants and animals live with a complex relationship that exists between them and their environment Carbohydrates are the main source of energy for plants as well as animals including man. But only plants can manufacture them from atmospheric carbon dioxide and water in the presence of sunlight. In the process they release oxygen. Animals depend on plants or other animals for their supply of carbohydrates. Animals use atmospheric oxygen to burn carbohydrates to produce the energy needed for their activities. And in the process, they release carbon dioxide. Thus a subtle balance is maintained between oxygen and carbon-di-oxide in our atmosphere. If it is disturbed, it can spell disaster.
Who Disturbs the Balance ?-Now, who has the ability to disturb this balance to pollute the environment? Not the plants. And not the animals barring human beings. Only man has the ability to manipulate things. And I only he has the ability to pollute the environment. Well if it is done in limits, there is not much harm. But as we know, comfort and greed have been the two main traits of man. And science has been assisting him in both. ‘
How is Environment Polluted ?-The faster and more comfortable means of transport-steam, diesel, and electric locomotives; petrol or diesel-run cars, buses or trucks-all pollute the air. Remember, electricity is mostly produced by thermal power plants.
Chemical fertilizers pollute the earth and as a result all our agricultural produce. Excessive use of pumps drawing underground water for irrigation has resulted in lowering the water-table considerably. As governments subsidize chemical fertilizers and provide free power to pumps, they are being used indiscriminately in the hope of increasing production.
Industrial developments, particularly of the chemical industry, pollutes not only air but also water in the rivers making their water undrinkable. AS 8 result there is a crisis of potable water:
Moreover,- the current craze for refrigeration and air-conditioning in producing excessive CFC the gas that 13 destroying the ozone layer exposing us to harmful ultraviolet rays from the sun.
