Some Solutions to Combat Delhi Smog

Since the past decade, Delhi has been witnessing one of the world’s worst smog ever in October and November. Diwali and farmers are blamed every year for causing such a hazardous situation for the national capital. However, Delhi shies away from changing itself to solve the problem once and for all. It is easy to put the blame game on others, and do nothing. The Delhi Government has taken some steps to minimize air pollution, but it is usually too little too late.

More than the Delhi Government, the current infrastructure and apathy of the citizens towards the environment of Delhi are more responsible for the Great Smog. Many of Delhi’s power plants are located in the suburbs, which are completely closed during the smog period. Construction work that generates too much fly ash is also halted all across Delhi. Usually, the order from the Government comes after Delhi gets completely engulfed in smog. On the other hand, little changes in lifestyle and infrastructure could have worked better for Delhi, which exists in a place in other parts of the country. Some of them are listed below.

1)Use Delhi Metro :
Delhi metro is one of the quickest, cleanest, and easiest modes of transportation in Delhi. The carbon footprints of Delhi Metro is significantly lower than that of all other transportation. Delhi metro has expanded to connect every nook and corner of the national capital. Delhi metro over the years is increasingly becoming more and more eco-friendly by installing solar panels, providing buses and e-rickshaw, and even taxis for last-mile connectivity. Despite all the good efforts, Delhi metro is yet to attract every commuter across the city owing to its expensive ticketing costs. Kolkata metro may be an example of a cheap metro which attracted commuters from all classes due to its cheap rates.

2)Expand Delhi Suburban Railway :
Similar to the Delhi Metro, Delhi has a good network of railway lines towards the suburban cities of Ghaziabad, Gurgaon, Faridabad, Sonipat, and Meerut. However, most of the tracks are used for long-distance trains and freight trains. Delhi has a ring railway which remains completely disused today. Suburban services are unattractive to the citizens, having little or no interchange with major bus or metro stops. Delhi does not have a monorail, tram, or any other form of transit other than the metro. Thus reliant on the usage of roads is heavy, causing huge traffic jams. Local trains of Mumbai are a good example of how suburban railways are used by a large chunk of the city population.

3)Lack of Greenery :
Delhi never used to lack greenery despite being the capital of various dynasties and empires. The Mughals and even the British were fond of gardens and open spaces which serves not only as a place for recreation but also as a source of fresh air and oxygen. Delhi today has grown beyond its borders and has eaten down even the small pockets of greenery that remained. Today only the southern parts of Delhi have some open space, where big, old trees are being felled for fields, locally called maidans, for sports and yoga. Nearby cities like Chandigarh, Jaipur and Agra have significantly less pollution due to large areas of natural vegetation within the city boundaries.

4)Unreliable Bus Service :
Bus service across the city is not that reliable either, prompting most people to use either private cars or bikes for transportation. Private cars and bikes are the biggest sources of air pollution in the city. Chennai has an excellent network of bus service catering 80% of the local transportation. Buses in Delhi are usually off-route, unfriendly, infrequent, and irregular, apart from being expensive, causing most of the population to stay away from using them.

5)Promotion of Green Fireworks :
No steps have been taken by the Government to stop the sale of banned fireworks, which cause too much pollution. Green fireworks, on the other hand, release significantly lower amounts of pollutants, thus can curb the sudden spike in pollution levels just after Diwali. As green fireworks are a bit on the pricier side, most sellers do not sell them to attract more customers. The Government, instead of promoting green fireworks and banning the illegal, is confused about what rules to apply. Banning illegal fireworks and promoting green fireworks comes way too late when most crackers are sold, and the crackers are unclassified whether illegal or not. Assam and the north-eastern states are doing well in this regard strictly allowing only green fireworks to be sold.

We all need to join hands and save our environment. Can you suggest some measures to do so? Tell us in the comment section below.

RT-PCR Test of Covid-19

Of all the Covid-19 tests that came to light in the wake of the Covid-19 pandemic situation globally, the RT-PCR Test stood out as the ultimate Covid-19 test. Its full-form is reverse transcription polymerase chain reaction. RT-PCR Test, when invented, used to cost as much as Rs. 5000 and was unaffordable by common people. However, as production grew, following advancement in technology, the price of RT-PCR Test has come down to as low as Rs. 300. In this article, let us see how this test works.

The sample is collected using a nose swab from your throat and nose. A swab is a thin, flexible stick that is inserted in your nostrils and throat to collect the virus. Covid-19 virus, if present, will get accumulated in the stick. The sample then reaches the laboratory, where the virus is extracted. The extraction process isolated genetic material from the sample, including genetic material of any viruses that may be present. The third step is the PCR, or polymerase chain reaction, in which millions of copies of the virus are produced for detection. Without the PCR, the number of viruses in the sample is too small to be detected. If Covid-19 is present, then the chemicals used in the process produce fluorescent light. It is the signal to suggest that the sample contains the Covid-19 virus.

A positive test result means that it is very likely you have Covid-19. If you test positive, don’t panic. Contact your doctor or healthcare provider, and follow the quarantine and self-isolation rules. Most people will recover following mild or no symptoms. A negative test result means you are unlikely to be affected by Covid-19 at the time of the test. However, you still have to follow all precautions given by the Government in your state, as you are still vulnerable to Covid-19 at the time of test or afterwards. Due to high sensitivity, you may test Covid-19 positive if you had been infected by Covid-19 a few weeks back and have recovered from it since then.

RT-PCR Test has numerous advantages:

  1. It delivers a report within 24 hours.
  2. It is the most reliable and accurate Covid-19 test, which can detect even residual virus, such as remnants of a virus from a near-past infection.
  3. Collection of sample is also hassle-free, and it could be processed in railway stations, entry and exit checkpoints, office buildings, that is it does not consume a large space and do not require extremely skilled labour.

Advantages of the RT-PCR Test made us possible to test for Covid-19 at tourist destinations at a minimal cost and also tour hassle-free in most tourist destinations in the country.
