Addressing water pollution is another critical aspect, as untreated wastewater pollutes Delhi's waterways and poses health risks to residents.

Citizens should carpool, use bicycles, and public transport to reduce traffic congestion and air pollution

Delhi is one of the most polluted cities in the world. Citizens of Delhi can play a crucial role in reducing this pollution by adopting sustainable modes of transportation. Carpooling, using bicycles, and opting for public transport are three effective ways to reduce traffic congestion and air pollution in the city.

Carpooling

Carpooling is a great way to reduce the number of private vehicles on the roads, thereby decreasing traffic congestion and lowering carbon emissions. With the rapid growth of the corporate sector in Delhi, carpooling has become an increasingly popular option, especially among office-goers. By sharing empty seats in a vehicle, commuters can save money, time, and fuel. Carpooling apps, such as Quick Ride, have made it even easier for people to find ride-sharing options and have contributed to reducing traffic and pollution.

Using Bicycles

Cycling is a clean and environmentally friendly mode of transportation. Studies have shown that shifting to a non-motorised transport regime can help Delhi avoid carbon dioxide emissions and reduce particulate matter (PM) 2.5 exposure, which is hazardous to human health. However, the lack of dedicated bicycle lanes and infrastructure in Delhi poses a safety risk for cyclists. There have been numerous cases of accidents involving cyclists, with records showing that 249 cyclists lost their lives on Delhi roads between 2017 and 2021. Despite the risks, many Delhi residents choose cycling as their primary mode of transportation due to its low cost.

Public Transport

Public transport, including the Metro, overhead rail, and bus services, offers an affordable and safe alternative to private vehicles. By encouraging greater use of public transport, the government can help reduce the number of private vehicles on the roads, which contribute significantly to air pollution. For example, private vehicles account for 40% of pollution in Delhi-NCR. Additionally, public transport can help alleviate traffic congestion, making travel more convenient and efficient for commuters.

In conclusion, citizens of Delhi can actively contribute to reducing pollution and traffic congestion by adopting carpooling, using bicycles, and opting for public transport. These choices not only benefit the environment but also offer economic and health advantages to individuals.

People should use CNG in vehicles as it's a cleaner fuel than petrol or diesel

Delhi is one of the most polluted cities in the world, with air pollution presenting a severe risk to the health of its citizens. To combat this, citizens of Delhi can take several measures to reduce pollution and improve air quality. One of the most effective ways is to encourage the use of Compressed Natural Gas (CNG) in vehicles as it is a much cleaner fuel option compared to petrol or diesel.

CNG is a compressed natural gas that has been processed to take up less space, allowing for more efficient storage. It is considered a much cleaner alternative to traditional petrol and diesel fuels. Vehicles powered by CNG emit significantly lower levels of harmful pollutants, such as carbon monoxide, nitrogen oxides, and hydrocarbon emissions. This makes CNG an eco-friendly choice that helps reduce a vehicle's carbon footprint. By switching to CNG, citizens of Delhi can play a crucial role in reducing air pollution and improving the city's air quality.

CNG vehicles produce lower levels of greenhouse gas emissions and air pollution compared to petrol or diesel engines. They emit fewer carbon emissions, which contributes to reducing global warming and climate change. Additionally, CNG is stored in high-pressure cylinders or tanks, ensuring safe and efficient storage. While refuelling infrastructure for CNG vehicles may be more limited, the benefits of reduced emissions and pollution far outweigh this inconvenience.

Another advantage of CNG is its cost-effectiveness. CNG fuel is generally cheaper than petrol, resulting in lower running costs for vehicle owners. This makes it an economically viable option, especially for those who rely on their vehicles for daily commutes. Furthermore, CNG vehicles offer higher fuel efficiency, providing better mileage and reducing the frequency of refuelling.

Citizens of Delhi can actively contribute to reducing pollution by opting for CNG-powered vehicles or, if they already own a petrol car, by converting it to run on CNG. This can be achieved through factory-fitted CNG kits or aftermarket installations, ensuring that their vehicles produce fewer emissions and have a reduced environmental impact.

In conclusion, by choosing CNG over petrol or diesel, the citizens of Delhi can make a significant difference in reducing air pollution and improving the city's air quality. CNG is a cleaner, more eco-friendly, and cost-effective fuel option that can help mitigate the severe health risks associated with air pollution in the city.

Individuals should check pollution levels before going outside and wear masks when necessary

Delhi is one of the most polluted capital cities in the world, with the worst air quality of any city. Its air quality index (AQI) is often described as "poor" or "severe", and it has even reached "hazardous" levels.

To protect themselves from the harmful effects of air pollution, individuals in Delhi should check the AQI before going outside. There are various apps and websites that provide real-time AQI data for different areas of Delhi. If the AQI is poor, it is recommended to limit outdoor activities and exertion. If possible, avoid going outside altogether and opt for indoor activities instead.

When the AQI is poor, it is essential to wear a mask when going outside, especially for children during their commute, as their developing lungs are more susceptible to long-term damage. N95 masks are recommended as they provide effective protection against pollution. Masks are also crucial for individuals with existing respiratory issues. In addition to masks, individuals can also use air purifiers to reduce their exposure to indoor air pollution.

The ideal time for outdoor activities in Delhi is between 9 am and 3 pm, when pollution levels are generally lower due to sunlight. Early mornings and evenings tend to have higher pollution levels, so it is best to avoid outdoor activities during these times.

Residents should avoid personal bonfires and report any incidents of waste burning to the authorities

Delhi is one of the most polluted cities in the world, with air pollution presenting immediate and long-term health risks to its residents. While the government has implemented various measures to curb pollution, the citizens of Delhi also have a crucial role to play in reducing pollution levels. One of the most important actions that residents can take is to avoid personal bonfires and report any incidents of waste burning to the authorities.

Burning waste, such as leaves, old tyres, plastics, and other items, is a major contributor to air pollution in Delhi. The smoke released from these fires contains harmful pollutants, including particulate matter, acids, chemicals, and toxic gases. When inhaled, these pollutants can have detrimental effects on human health, leading to respiratory diseases, allergic rhinitis, asthma, lung cancer, and other serious illnesses. Therefore, it is essential that residents refrain from burning any waste and instead, adopt alternative waste disposal methods.

The practice of burning waste is deeply ingrained in some cultural and religious traditions, such as the festival of Bhogi, where burning waste is believed to "ward off the evil eye with fire". While this tradition may have originated from burning only organic items, it has evolved to include the burning of various types of waste. Recognising the harmful impact of waste burning, the Greater Chennai Corporation has taken steps to prevent pollution during the festival by instructing residents to burn waste after 7 p.m. or before 3 a.m. and advising people to stay indoors during the burning.

To effectively address the issue of waste burning in Delhi, residents should take a proactive approach. Firstly, they should avoid burning any waste themselves and opt for alternative methods of waste disposal, such as recycling, composting, or utilising waste management services provided by the municipality. Secondly, they should report any incidents of waste burning by others to the relevant authorities. The Delhi Fire Services, for example, have prioritised calls regarding waste burning and deployed fire tenders to address these incidents immediately. Additionally, residents can utilise helpline numbers and emails to report waste burning and play an active role in reducing air pollution.

By avoiding personal bonfires and reporting incidents of waste burning, residents of Delhi can significantly contribute to reducing air pollution levels in the city. This simple yet impactful action can help protect the health and well-being of all citizens, especially those who are more vulnerable to the harmful effects of air pollution, such as children and the elderly.

Delhiites should push for more trees to be planted in their neighbourhoods and across the city

Delhi is one of the most polluted cities in the world, with air quality that poses serious risks to human health. To address this issue, Delhiites should advocate for more trees to be planted in their neighbourhoods and across the city. Trees are a natural solution to improving air quality and can help mitigate the harmful effects of pollution on people's health and the environment.

Trees play a vital role in reducing air pollution by directly removing pollutants from the atmosphere. They act as natural filters, absorbing gaseous pollutants such as carbon dioxide, sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and ground-level ozone through their leaves. The leaves of trees are covered in tiny pores called stomata, which inhale air containing these toxic pollutants. Once absorbed, the gases diffuse within the inner surfaces of the leaves and are broken down, reducing their concentration in the air. This process also helps to improve the air quality index, making the air safer to breathe for Delhi's residents.

In addition to absorbing gaseous pollutants, trees also help to reduce particulate matter in the air. Particulate matter, such as PM2.5, is a major contributor to hazy skies and can cause serious health issues when inhaled. Trees act as a barrier, temporarily catching these tiny particles on their leaves, branches, and trunks. When it rains, the rainwater washes away the trapped particles, carrying them into the soil or dissolving them into stormwater. This process helps to reduce the amount of particulate matter in the air, improving air quality and reducing the risk of respiratory and other health issues for Delhi's residents.

Trees also provide additional benefits that contribute to reducing pollution and improving the environment in Delhi. They can increase property values, regulate temperatures by providing shade and reducing the urban heat island effect, and intercept stormwater runoff, reducing the risk of flooding. Additionally, trees can save energy by providing shade and reducing the need for air conditioning, which in turn reduces the consumption of energy from polluting sources.

Delhiites can take an active role in improving their city's air quality by pushing for more trees to be planted. This can be done through individual initiatives, such as planting trees in their neighbourhoods, as well as by advocating for larger-scale tree-planting programmes and policies. By working together with their communities and local governments, Delhi's residents can help create a greener and healthier environment for themselves and future generations.
