Cleaning Air Pollution: Innovative Ways To Breathe Easy

Air pollution is a serious issue that affects people worldwide and puts human and animal life at risk. It is caused by human and natural sources, such as emissions from vehicles, planes, and factories, as well as wildfires and volcanic eruptions. The most common and dangerous air pollutants include ozone, particulate matter, carbon monoxide, lead, sulfur dioxide, and nitrogen oxide. These pollutants have severe impacts on human health, including respiratory illnesses, heart disease, lung cancer, and an increased risk of stroke. Additionally, air pollution contributes to environmental damage and climate change, threatening the viability of our planet. Addressing air pollution requires a combination of individual actions and government interventions. Individual actions, such as reducing vehicle usage, switching to electric cars, and conserving electricity, can help lower emissions. Governments also play a crucial role in implementing regulations, promoting renewable energy sources, and creating laws to control toxic emissions. By working together, we can effectively combat air pollution and improve the well-being of people and the planet.

Reduce car usage, or switch to electric vehicles

Reduce Car Usage

One of the most effective ways to reduce air pollution is to reduce car usage. This can be achieved by:

• Carpooling: Sharing rides with others reduces the number of vehicles on the road and, therefore, the amount of pollution emitted.
• Opting for Public Transportation: Buses, trains, and subways are more efficient than private cars as they can carry more passengers, reducing the overall number of vehicles on the road.
• Cycling or Walking: For shorter distances, consider walking or cycling instead of driving. This not only reduces air pollution but also improves your health and reduces traffic congestion.
• Telecommuting: Working remotely reduces the need to commute by car, thereby lowering vehicle emissions.

Switch to Electric Vehicles

Electric vehicles (EVs) are a cleaner alternative to traditional gasoline-powered cars. Here's how they help reduce air pollution:

• Zero Tailpipe Emissions: EVs produce no tailpipe emissions, which means they do not release harmful pollutants like nitrogen oxides and particle emissions into the air during operation.
• Lower Carbon Footprint: Even when accounting for the electricity used for charging, EVs typically have a smaller carbon footprint than gasoline cars. The carbon emissions associated with EV charging depend on the energy sources used to generate electricity, and the continued shift towards renewable energy sources will further reduce their carbon footprint.
• Energy Efficiency: EVs are far more energy-efficient than gasoline cars. They use approximately 87-91% of the energy from the battery for propulsion, compared to gasoline vehicles, which only convert about 16-25% of the energy from gasoline.
• Reduced Greenhouse Gas Emissions: By electrifying transportation, we can significantly reduce emissions of greenhouse gases (GHGs) and other air pollutants. This is crucial in addressing climate change and improving air quality, especially in urban areas.
• Improved Air Quality: Transitioning from gasoline to electric vehicles reduces harmful ground-level ozone and fine particulate matter (PM2.5) pollution, which are detrimental to public health and the environment.

Avoid backyard fires

Backyard fires are a significant source of air pollution, especially in metropolitan areas. The smoke from burning wood contains gases and fine particles, which are also called particle pollution or particulate matter. These particles are linked to diseases and health conditions such as asthma, Alzheimer's, cancer, diabetes, preterm births, and premature death.

To avoid contributing to air pollution through backyard fires, it is important to consider some alternatives and best practices. Firstly, switching to natural gas or propane is a cleaner option that reduces harmful air pollutants. Conversion kits are available for existing fire pits or rings, making it a convenient choice. It is also crucial to check local laws and ordinances, as some local governments have implemented restrictions on backyard recreational fires.

If you choose to burn wood, there are ways to minimize the impact on air quality. Firstly, only burn seasoned, dry wood, which burns hotter and cleaner. Moisture content plays a crucial role, and using a moisture meter can help ensure the firewood is at an optimal level of about 20%. Covering stacked wood promotes drying while allowing good airflow.

It is important to avoid burning wood during air quality alert days when pollution levels are already elevated. Additionally, never burn green wood, construction waste, plastic, garbage, or yard waste, as these materials create more smoke and can release toxic substances. Taking extra care in regions prone to brush fires is also essential.

By following these guidelines, individuals can enjoy their backyard fires more responsibly, minimizing the impact on their neighbors' and community's health and well-being.

Plant and care for trees

Trees are an excellent way to clean the air and improve air quality. They can directly remove pollutants from the air and release clean oxygen for us to breathe. Trees also help to cool the air by providing shade, which reduces the need for conventional air conditioning and the emissions that come with it.

When planting trees to combat air pollution, it's important to choose the right species for the job. Some trees are more effective at filtering pollutants than others. For example, conifers like pines and cypresses are good natural air purifiers because their dense, needle-like leaves are very effective at trapping pollutants. They are also evergreen, so they work all year round. Other effective species include silver birch, yew, and elder trees, which have hairy leaves that trap pollution. London plane trees, on the other hand, emit high levels of volatile organic compounds, which can be bad for air pollution.

When planning where to plant, it's important to consider the local context. Trees need to be planted close to sources of pollution, but in some cases, planting tall trees in narrow streets surrounded by tall buildings can prevent pollution from dispersing. Hedges or green walls are often a better choice in these situations. It's also important to ensure biodiversity by not planting too many of the same species in one area.

Caring for trees is also important to ensure their longevity and effectiveness in combating air pollution. This includes regular maintenance such as pruning, watering, and providing adequate space for root growth.

By planting and caring for the right types of trees in the right places, we can harness the power of nature to help clean the air and improve the health of our communities.

Use less energy

Energy generation is one of the greatest sources of air pollution. Energy plants that burn fossil fuels to create energy, such as coal, are the primary sources of air pollutants like particulate matter, nitrogen oxide, sulfur dioxide, volatile organic compounds (VOCs), and carbon monoxide.

Using less energy is a viable strategy to reduce air pollution. Here are some ways to reduce energy usage and improve air quality:

Improve Energy Efficiency at Home

A typical household in the US uses about 11 million megawatt-hours (MWh) of electricity per year for lighting and appliances. By reducing energy use at home, you can help improve outdoor air quality. Here are some tips:

• Set your thermostat to save on heating and air conditioning.
• Switch off lights when not in use and use more energy-efficient light bulbs.
• Ensure your house is well-insulated and weather-tight to prevent heat or cooled air from escaping.
• Choose energy-efficient appliances.

Green Building Design

The design of "green" buildings and infrastructure can improve energy efficiency. For example, incorporating windows in a building's design to allow natural sunlight to provide heat during winter reduces the need for heating with fossil fuels.

Improve Efficiency of Fossil Fuel Power Plants

Fossil fuel power plants, being among the biggest air polluters, can employ carbon capture and storage technology to reduce carbon emission levels per unit of electricity generated. Additionally, smart combustion unit design can improve efficiency by utilizing the thermal heat from one unit to power others, reducing heat loss and, consequently, pollution.

Switch to Renewable Energy Sources

Renewable energy sources, such as solar power, are highly energy-efficient. Once installed, they require less investment to operate and produce power from natural sources.

Improve Energy Efficiency in Transportation

Transportation is a significant contributor to air pollution, with cars, SUVs, and trucks travelling trillions of miles each year in the US alone. Improving the energy efficiency of vehicles can help curb this pollution. Electric vehicles are becoming more prevalent, and policies to phase out gasoline or diesel vehicles are gaining traction. While electric vehicles currently represent a small fraction of the vehicles on the road, their impact on reducing local urban air pollution is significant.

Mandatory Standards and Retrofits for Buildings

Mandatory building standards and retrofits that reduce energy consumption within buildings can substantially lower the demand for power generation, positively impacting air pollution levels.

Reduce emissions from garden equipment

Garden equipment, such as lawnmowers, leaf blowers, and snow blowers, can contribute significantly to air pollution, especially when powered by gas or small internal combustion engines. These pieces of equipment often lack pollution control devices, and an hour of running a lawnmower, for example, can produce a similar amount of pollution as driving a car for 100 miles.

To reduce emissions from garden equipment, it is important to consider switching to electric alternatives. Electric equipment can eliminate emissions from these sources, improving both local and regional air quality and reducing the occurrence of associated health issues such as asthma, cardiovascular disease, and premature death. Electric equipment is also quieter, reducing noise pollution, and produces less vibration, resulting in less user fatigue.

For those using electric garden equipment, it is important to have sufficient charging infrastructure and enough batteries to support the use of the equipment. Working with manufacturers or retailers can help determine the number of charging stations and backup batteries required.

In addition to switching to electric equipment, proper recycling of old gas-powered equipment is crucial. Recycling ensures the removal of outdated equipment from the supply chain and proper waste disposal. Some organizations and programs offer incentives for replacing gas-powered equipment with electric alternatives, such as discounts or cost-sharing opportunities.

By implementing these strategies, individuals, businesses, and governments can play a significant role in reducing emissions from garden equipment, contributing to cleaner air and improved public health.
