Humans' Role In Fixing Air Pollution

Air pollution is a pressing issue that affects the health of people and the planet. It is caused by the emission of harmful particles, chemicals, and gases into the atmosphere, which can have detrimental effects on both the environment and human health. While the problem of air pollution is significant, there are ways in which humans can help to fix it.

One way to tackle air pollution is to reduce emissions from vehicles. This can be achieved by encouraging the use of public transportation, biking, or walking instead of driving. Additionally, the use of electric cars or cars with increased fuel efficiency can also help to decrease pollution levels. Another way to reduce vehicle emissions is to keep engines tuned and tires properly inflated, as this decreases fuel consumption.

In addition to reducing vehicle emissions, humans can also address air pollution by conserving energy. This can be done by turning off lights when not in use, investing in energy-efficient appliances, and setting the thermostat higher in the summer and lower in the winter. Individuals can also contribute by monitoring air quality warnings and taking appropriate actions on days with high pollution levels, such as reducing overall car usage and avoiding idling.

Furthermore, humans can support the development and implementation of policies and laws that aim to restrict air pollution. For example, the Clean Air Act in the United States has helped to improve air quality by setting air quality standards and requiring states to have plans to address air pollution and emissions reduction. Similar laws and regulations have been passed in other countries, such as the United Kingdom and China.

By taking a combination of individual, community, and governmental actions, humans can work towards fixing air pollution and improving the health of the planet and its inhabitants.

Reduce car journeys, use public transport, walk or cycle

Reducing car journeys, using public transport, and opting to walk or cycle are all effective ways to reduce air pollution.

Firstly, reducing car journeys is a straightforward way to decrease emissions. The fewer miles driven, the fewer emissions produced. This can be achieved by walking or cycling when possible, or using public transport. Many cities are enhancing their public transportation systems with new technologies, cleaner fuels, and better services, which provide incredible benefits in terms of traffic management, economic development, equitable transportation access, and public health. By increasing ridership on public transit, more fuel is conserved, air pollution decreases, and the region’s carbon footprint is reduced.

Walking and cycling are excellent alternatives to driving, offering health benefits and reducing emissions. Evidence shows that investments in policies that promote safe cycling and walking can play a crucial role in shaping health, mitigating climate change, and improving the environment. Active commuting is associated with about a 10% decrease in the risk of cardiovascular disease and a 30% decrease in type 2 diabetes risk. Additionally, cancer-related mortality is 30% lower among bike commuters. Walking and cycling also address problems resulting from current transport patterns, including emissions of air pollutants, greenhouse gases, and noise, as well as traffic injuries.

To encourage walking and cycling, it is important to redesign urban spaces to meet daily needs, such as access to jobs, education, healthcare, and recreation, within distances that can be safely covered using active mobility means and public transport. Infrastructure for safe walking and cycling, such as dedicated paths and secure parking for bikes, is crucial. Trip-end facilities, such as changing rooms at workplaces, can also facilitate active travel.

In summary, reducing car journeys, utilizing public transport, and opting to walk or cycle are effective strategies to reduce air pollution. These strategies not only decrease emissions but also provide health benefits and contribute to improved urban planning and public health.

Switch to an electric or hybrid car

Electric vehicles (EVs) are a cleaner alternative to gasoline or diesel-powered cars and trucks. They produce fewer climate-warming emissions and have no tailpipe emissions. Research has shown that an EV is typically responsible for lower levels of greenhouse gases than an average new gasoline car.

EVs are more energy-efficient than gasoline vehicles. They use approximately 87%–91% of the energy from the battery and regenerative braking to propel the vehicle, whereas gasoline vehicles only convert about 16%–25% of the energy from gasoline into movement.

Plug-in hybrid electric vehicles (PHEVs) are also a good option for reducing air pollution. They have smaller batteries than EVs and can be charged through regenerative braking or by plugging into an outlet. PHEVs can be a better option than EVs in certain circumstances, such as when most driving is done within a few miles of home, or in areas where electricity is primarily generated by burning coal.

Switching to an electric or hybrid car can help to reduce air pollution and improve air quality. This is especially important for vulnerable populations such as children, the elderly, and people with chronic cardiovascular or pulmonary disease, who are more susceptible to the harmful effects of air pollution.

Service your car regularly

Regular car maintenance and servicing are essential for reducing air pollution. Here are some reasons why servicing your car regularly is crucial:

Reduced Emissions

Well-maintained cars produce cleaner emissions. Regular servicing ensures that your car's engine, filters, and other components are in good condition and functioning efficiently. This helps to minimise the release of harmful pollutants into the atmosphere.

Improved Fuel Efficiency

Servicing your car can also improve its fuel efficiency. Properly tuned engines, well-maintained tyres, and regular oil changes contribute to better fuel economy. This not only reduces air pollution by lowering fuel consumption but also saves you money.

Longer Vehicle Lifespan

Regular maintenance extends the lifespan of your vehicle. By identifying and addressing issues during servicing, you can prevent major problems from developing. This not only saves you from costly repairs but also reduces the need for frequent vehicle replacements, which helps to decrease air pollution associated with vehicle manufacturing.

Enhanced Safety

Servicing your car improves its overall performance and safety. Regular maintenance checks can identify potential safety hazards, such as faulty brakes or worn-out tyres, and ensure that they are rectified. This not only reduces the risk of accidents but also contributes to a safer driving experience for you and your passengers.

Cost Savings

Regular servicing can help you save money in the long run. By identifying and fixing issues early on, you can avoid costly repairs or part replacements down the line. Additionally, well-maintained cars tend to be more fuel-efficient, saving you money on fuel costs.

In conclusion, servicing your car regularly is a crucial step in reducing air pollution. It not only minimises emissions and enhances fuel efficiency but also prolongs the lifespan of your vehicle, improves safety, and saves you money. By prioritising regular car maintenance, you can play a significant role in improving air quality and protecting the environment.

Avoid idling your car

Vehicle emissions are the number one source of air pollution in many areas. Idling your car can waste money and natural resources, damage vehicles, pollute the air, and harm your health. Here are some reasons why you should avoid idling your car:

Idling Wastes Fuel and Money

For each hour spent idling, a typical light-duty truck burns approximately one gallon of diesel fuel, and a typical car wastes one-fifth of a gallon of gasoline. Idling for just 10 seconds uses more fuel than turning off the engine and restarting it. This is like burning dollar bills!

Idling Damages Vehicles

Idling is not an effective way to warm up your engine. A better way to warm your vehicle's transmission, tires, suspension, steering, and wheel bearings is to simply drive off slowly. Your car tends to warm up faster this way. Idling can also cause damage to your engine, as it is made up of many moving parts.

Idling Causes Air Pollution

An idling vehicle releases harmful chemicals, gases, and particle pollution ("soot") into the air, contributing to ozone, regional haze, and global climate change. Every gallon of gas burned produces more than 20 pounds of greenhouse gases. Air pollution has been linked to asthma and other respiratory problems.

Idling is Unhealthy

The pollution in exhaust can aggravate asthma and allergies, as well as cardiovascular and respiratory diseases. Higher levels of air pollution have been linked to increased school absences, hospital visits, and even premature deaths. Vehicle emissions are still present and harmful even when you can't see the exhaust. Children are more sensitive to air pollution because they breathe 50% more air per pound of body weight than adults.

To reduce air pollution and protect your health, avoid idling your car whenever possible. Turn off your engine when waiting in drive-through lines or when stopped for more than a few seconds. This simple action can make a significant difference in improving air quality and reducing harmful emissions.

Avoid busy roads when walking or cycling

Walking or cycling on busy roads can expose you to high levels of air pollution, which can be detrimental to your health. Here are some tips to avoid busy roads when walking or cycling:

• Plan your route in advance: Use tools such as Google Maps or Open Street Maps to identify quieter routes with less traffic. Look for roads with lower speed limits, dedicated bike lanes, or shared-use paths for pedestrians and cyclists.
• Consider alternative transportation methods: If possible, opt for public transportation or drive part of the way to avoid busy roads. Some public transportation systems allow bicycles on board, providing a convenient option for cyclists.
