Pollution is the presence of toxic substances in the natural environment that cause adverse effects. It can take the form of energy such as heat, light or noise. The chief forms of pollution include noise pollution, light pollution, air pollution, soil contamination, radioactive contamination, water pollution and thermal pollution. Every living species shares the natural resources on this planet. What happens in the environment affects all the living species and the planet as a whole. Pollution has several negative effects on human life.
Effects of Pollution on Human Life
The greenhouse gas emission in the atmosphere causes rise in the temperature of earth that adversely affects the human life. Humans are chiefly responsible for creating pollution in the atmosphere. While human activities are a major cause of pollution in the atmosphere, pollution in the atmosphere has direct impact on them. Let us have a look at the effects of pollution on human life in detail below:
The poor quality of air can kill many organisms including human beings. Pollution can cause several diseases like throat inflammation, asthma, congestion, cardiovascular diseases and respiratory diseases. It damages the immune system, reproductive system and the endocrine system of humans. Older people are more vulnerable to diseases caused by air pollution. Those with lung and heart disorder are at further risk.
The toxic chemicals in the air settle in to water and plant resources and the poison travels up the food web.
Drinking contaminated water may cause several ailments and digestive problems in humans. The ailments such as typhoid and amoebiasis are caused by drinking polluted water.
Contamination of drinking water is majorly responsible for causing deaths in developing countries. It is estimated that approximately 14,000 deaths are caused per day due to water pollution.
Water pollution adversely affects marine life which is one of the chief sources of food for humans.
Chemical and radioactive substances in air can cause chronic diseases such as cancer and may also cause birth defects.
Soil pollution, deforestation and improper waste disposal put plant and animal life in danger. Contaminated soil by chemicals becomes infertile and inappropriate for crops and other plant life. This hinders the production of food and can lead to malnourishment. Toxic soil may produce contaminated food and may adversely affect the health of one who consumes it.
Noise pollution can damage physiological and psychological health of humans. It can cause disturbance in many day to day activities of humans such as sleeping, studying, meditation, etc. Excessive exposure to noise pollution can lead to hearing problem, permanent hear loss, hypertension, stress, high blood pressure and cardiovascular effects. Children and old age people are more prone to such problems. It may also interfere with learning, concentration and behaviour of children.
Conclusion
We live in the ecosystem where everything is interrelated. We have severely polluted the environment since decades and are facing its repercussions now. We are now very well aware of the adverse effects of pollution. It is vital to make efforts towards green and clean environment to bring positive changes.
