Answer:
Environmental problems in Delhi, India, are a threat to the well-being of the city's and area's inhabitants as well as the flora and fauna. Delhi, the ninth-most populated metropolis in the world (second largest if the entire NCR includes especially Faridabad and Gurugram– Haryana, is one of the most heavily polluted cities in India,[1] having for instance one of the country's highest volumes of particulate matter pollution.[2] The air quality index of Delhi is generally moderate (101–200) level between January to September, and then it drastically deteriorates to Very Poor (301–400), severe (401–500) or hazardous (500+) levels in three months between October and December, due to various factors including stubble burning, fire crackers burning during Diwali and cold weather.[3][4][5] In May 2014 the World Health Organization announced New Delhi as the most polluted city in the world.[6]
Overpopulation and the ensuing overuse of scarce resources such as water put heavy pressure on the environment. The city suffers from air pollution caused by road dust and industry,[7] with comparatively smaller contributions from unclean engines in transportation, especially diesel-powered city buses and trucks, and 2-wheelers and 3-wheelers with two-stroke engines.[8] Another known cause of pollution is slow moving traffic due to pedestrians crossing the road just about anywhere
Explanation:
The air quality in Delhi, the capital territory of India, according to a WHO survey of 1650 world cities, is the worst of any major city in the world. It also affects the districts around Delhi [2][3] Air pollution in India is estimated to kill about 2.5 million people every year; it is the fifth largest killer in India. India has the world's highest death rate from chronic respiratory diseases and asthma, according to the WHO. In Delhi, poor quality air irreversibly damages the lungs of 2.2 million or 50 percent of all children.
On 25 November 2019, the Supreme Court of India made statements on the pollution in Delhi saying "Delhi has become worse than narak (hell)".[4] Supreme Court Justice Arun Mishra said that it is better to get explosives and kill everyone.[5]
India's Ministry of Earth Sciences published a research paper in October 2018 attributing almost 41% to vehicular emissions, 21.5% to dust and 18% to industries.[6] The director of Centre for Science and Environment (CSE) alleged that the Society of Indian Automobile Manufacturers (SIAM) is lobbying "against the report" because it is "inconvenient" to the automobile industry.[7]
Air quality index of Delhi is generally Moderate (101–200) level between January to September, and then it drastically deteriorates to Very Poor (301–400), Severe (401–500) or Hazardous (500+) levels during October to December due to various factors including stubble burning, road dust, vehicle pollution and cold weather.[8][9][10] In November 2017, in an event known as the Great smog of Delhi, the air pollution spiked far beyond acceptable levels. Levels of PM2.5 and PM 10 particulate matter hit 999 micrograms per cubic meter, while the safe limits for those pollutants are 60 and 100 respectively.[11]
Delhi's pollution problem is also caused by the factor of animal agriculture, as smog and other harmful particles are produced by farmers burning their crop in other states. About 80 percent of agriculturally used land is used for animal agriculture, so animal agriculture can also be attributed as a factor in Delhi's air pollution problem.[12] Initiatives such as a 1,600 km long and 5 km wide The Great Green Wall of Aravalli green ecological corridor along Aravalli range from Gujarat to Delhi which will also connect to Shivalik hill range is being considered with planting of 1.35 billion (135 crore) new native trees over 10 years to combat the pollution.[13]
Explanation:
The toxic levels of
air pollution
in and around Delhi is creating quite a menace. Adding to the severity, the changing weather conditions have locked the pollutants in the air and made the situation worse. Doctors are warning people of dire consequences and discouraging them from stepping outdoors. But what are the reasons behind this soaring pollution? We tell you:
1. National capital shares its border with the states of Haryana and Uttar Pradesh. One of the main reasons of increasing air pollution levels in Delhi is crop burning by the farmers in these states. Farmers burn rice stubbles in Punjab, Haryana and Uttar Pradesh. It is estimated that approximately 35 million tonnes of crop are set afire by these states. The wind carries all the pollutants and dust particles, which have got locked in the air.

2. Pollution caused by the traffic menace in Delhi is another reason contributing to this air pollution and smog. The air quality index has reached ‘severe’ levels. Vehicular emission is increasing the hazardous effects of air pollution and smog. The Central Pollution Control Board (CPCB) and the National Environmental Engineering Research Institute (NEERI) have declared vehicular emission as a major contributor to Delhi’s increasing air pollution.
3. As the winter season sets in, dust particles and pollutants in the air become unable to move. Due to stagnant winds, these pollutants get locked in the air and affect weather conditions, resulting in smog.
4. Another reason of air-pollution is over-population in the capital. Over-population only adds up to the various types of pollution, whether it is air pollution or noise pollution.
5. Investing less on public infrastructure is another reason of air pollution. In India, investment in public transport and infrastructure is low which leads to congested roads, and hence air pollution.
6. Large scale construction in Delhi-NCR is another culprit that is increasing dust and pollution in the air. Considering the dipping air quality, a number of construction sites have stalled work, as directed by the Delhi Government.
7. Industrial pollution and garbage dumps are also increasing air pollution and building-up smog in the air.
8. Despite the ban on cracker sales, firecrackers were a common sight this Diwali. It may not be the top reason for this smog, but it definitely contributed to its build up...
