write an article on effects of pollution
Answers
Answer:
Pollution occurs when the pollutants contaminate the natural environment that affects life on earth adversely. With urbanization and development in our lives pollution has reached its heights giving rise to global warming. Due to global warming human beings, animals and our environment are adversely affected. Environment, humans as well as animals are severely affected by pollution. Here is a look at the adverse effects of pollution:
Effects of Pollution on Human’s Life
Air pollution can cause respiratory diseases, increased risk of heart attack, asthma, and lung complications. It can also worsen the existing diseases.
Smog can damage the lungs and cause irritation in throat and eyes. People who already suffer from asthma are prone to have asthma attacks.
Dioxins present in the air can damage the liver, and also harm the nervous, immune and endocrine system and reproductive function in humans.
The toxic components from traffic and wildfire such as polycyclic aromatic hydrocarbons or PAHs in huge amounts can cause lung and eye irritation, liver issues and cancer.
Greenhouse gas emission in the atmosphere leads to warmer temperatures. Climate change leads to several issues like extreme weather, heat-related deaths, rising sea levels, acid rains and increasing number of diseases.
Noise pollution can damage the physical and mental health. Exposure to excessive noise pollution can cause stress, hypertension, sleep disturbance, rise in blood pressure, hear-loss and other adverse effects.
Effects of Pollution on Animal’s Life
Pollution causes threat to the habitat of animals and death in some events. There are several species that have also been pushed to extinction. Animals are affected by both direct and indirect pollution.
Oil spills affect marine life instantly causing large number of deaths. It causes immediate death of animals due to toxicity of oil, besides deaths caused, there are several other animals affected by oil spills. The oil pollutes marine and plant life which impacts animal life in number of ways such as decreased or impaired reproduction, neurological damage, and vulnerability to disease are common effects for long period even after the oil spills have been cleaned.
Water is polluted due to acid rain as the rain water drains towards lakes, ponds, streams and other water channels causing death of fish population. The decrease in fish population affects other wildlife that depends on fish for food.
Nutrient pollution leads to the dead zone areas in water channels with very little or no oxygen where it becomes difficult for marine life to survive.
Noise pollution can have severe effect on wildlife increasing the risk of death by disrupting the balance in predator or prey detection and disturbing the sound in communication. Over exposure to excessive sound can lead to hearing issues or permanent hear loss. It can also lead to change of usual habitat.
Effects of Pollution on Environment:
The toxic pollutants that enter in environment are consumed by the organisms through food and water or directly absorption through their skin. These toxins pass to the animals higher in the food chain and so on. Top predators are more vulnerable to experience various diseases, genetic mutations, birth defects, etc.
Ocean acidification is caused as the greenhouse gas carbon dioxide in the air gets dissolved in water resulting in the decrease of pH of the earth’s oceans.
Acid rains caused by pollution damage the forests, water channels and lands.
The population and diversity of birds and animals has shown decline or change of habitat to excessive noise pollution. Noise pollution also disrupts the communication and mating of certain species.
Sounds produced by military sonar, shipping traffic create rise in levels of underwater sound that disrupts the communication, hunting and mating of the marine species.
Conclusion
Hence, pollution has several adverse effects on the environment, human and animal life. Everything on earth is interrelated and depends on each other for effective functioning. As humans we need to stop harming nature and take steps towards prevention of pollution.
Answer:
pollution is the importance cause of our environment . environment is the most important part of all living and non living things.
pollution is cause by water,air and environment pollution. buses, car, bikes, truck , factory, and pouplaction is the main reason of pollution .
