What You'll Learn
Drive a car with poor fuel efficiency
Driving a car with poor fuel efficiency is a surefire way to contribute to pollution, particularly air pollution. Fuel inefficiencies harm the environment as more fuel consumption means more emissions, which contribute to higher air pollution. Vehicles are America's largest source of air pollution, generating about 28% of total US greenhouse gas emissions.
Cars with poor fuel efficiency tend to release more carbon dioxide (CO2) into the air. As CO2 is the primary greenhouse gas, its excessive release harms the climate. It accumulates in the atmosphere, trapping heat, and causing global temperatures to rise. This temperature increase leads to severe environmental impacts, such as rising sea levels, extreme weather events, and habitat loss.
The environmental impact of cars is largely due to fuel consumption and emissions of air pollutants and greenhouse gases. The extraction of petroleum products, for example, can damage local ecosystems, and the shipping of fuels creates a risk of environmental disasters, such as oil spills.
To drive a car with poor fuel efficiency and contribute to pollution, avoid regular maintenance, and ignore safe driving practices. Drive aggressively, accelerate quickly, and speed. Choose a vehicle with a large engine and poor fuel economy ratings.
Additionally, ignore measures to reduce pollution, such as keeping your tires properly inflated, which helps burn less fuel. Avoid electric, hybrid, or compact fuel-efficient gas vehicles, as these produce fewer emissions.

Burn trash in barrels and wood stoves
Burning trash in barrels and wood stoves is a highly inefficient way to dispose of waste. It creates more pollution and is worse for the environment than using a municipal incinerator. Fires in barrels rarely exceed 500°F, which is not hot enough for complete combustion, leading to harmful smoke and soot.
The smoke from burning trash in a barrel contains particulate matter, carbon monoxide, hydrogen chloride, hydrogen cyanide, benzene, styrene, formaldehyde, arsenic, lead, chromium, benzo(a)pyrene, dioxins, furans, and PCBs. These emissions are dangerous to human health and can cause eye and lung irritation, headaches, dizziness, coughing, wheezing, nausea, asthma, and even death.
Trash containing plastics, polystyrene (such as foam cups), CCA-pressure-treated wood, and bleached or colored papers can produce harmful chemicals when burned. For example, when CCA-pressure-treated wood (which contains arsenic) is burned, arsenic can be released into the smoke or remain in the ash. The smoke from backyard burning is released close to the ground, where it can be easily inhaled, and it can deposit chemicals on garden vegetables and soil. People can then be exposed to these chemicals by eating fruits and vegetables grown near the trash fire or in soil tilled with the ashes.
Backyard burning is prohibited in some states, such as New York, due to its negative health and environmental impacts. It is recommended to hire a sanitation service or work with your local community to develop a waste disposal service that is safe and environmentally friendly.

Use gas-powered lawn equipment
Gas-powered lawn equipment, such as leaf blowers and lawnmowers, is a significant contributor to pollution. These tools emit harmful gases and particles that adversely affect human health and the environment. According to the Environmental Protection Agency (EPA), gas-powered lawn equipment releases pollutants such as carbon monoxide, nitrogen oxides, and volatile organic compounds (VOCs). These emissions contribute to ground-level ozone and smog formation, leading to respiratory issues and other health problems.
Gas-powered lawn equipment also generates noise pollution, producing noise levels of up to 100 decibels, comparable to a chainsaw or jackhammer. This noise pollution disrupts humans and wildlife and can contribute to hearing loss over time.
The impact of gas-powered lawn equipment on the environment is often overlooked, and it is essential to consider alternatives. Electric lawn equipment, for example, is a more sustainable option as it emits no pollutants and is quieter. Electric mowers are also convenient, with no cords to restrict movement. While older electric mowers had limitations such as higher costs and shorter battery lives, newer models offer improved affordability and longer-lasting batteries.
Another alternative is reel mowers, which require no fuel or electricity and produce no emissions. However, they may not be suitable for larger lawns as they demand more physical effort to operate. Robotic mowers are another eco-friendly option, utilizing rechargeable batteries and producing no emissions or noise pollution. They maintain a consistent grass height, reducing the need for fertilizers and pesticides.
Some communities are taking action to address the pollution caused by gas-powered lawn equipment. Cities like Charleston, SC, and South Pasadena, CA, have transitioned to electric and manual tools for leaf blowing and lawn maintenance. In Baltimore, MD, an ordinance restricts the use of gas-leaf blowers to a specific period each year, with a complete prohibition to take effect in 2026. Boulder County, Colorado, has offered grants and incentives to encourage the switch to electric lawn and landscaping equipment. These initiatives aim to reduce pollution and noise levels associated with gas-powered equipment.

Don't air-dry clothing and linens
Air-drying clothing and linens can contribute to pollution in several ways. Firstly, it increases the use of household dryers, which consume a significant amount of energy and contribute to carbon dioxide emissions. Household dryers in the United States consume about 3% of residential energy, costing over $7 billion annually to power and emitting the equivalent of more than 27 million tons of carbon dioxide.
Secondly, tumble dryers are known to release microfiber pollution into the air. A recent study found that tumble drying a load of laundry releases a significant amount of potentially harmful microfibers into the air as those released during machine washing. These microfibers, tiny textile strands, can pose a threat to both environmental and human health. While using dryer sheets, fabric softeners, and improving lint filters can help reduce microfiber pollution, they do not eliminate it entirely.
Additionally, the type of energy used to power dryers can significantly impact emissions. In areas primarily powered by coal, dryers contribute to higher emissions compared to regions relying on sustainable options like hydroelectric power. Switching from a gas dryer to an electric dryer can result in varying emission changes, emphasizing the need for a cleaner energy grid.
Moreover, air-drying clothing may not always be feasible for everyone. Individuals may have concerns about line drying, such as stiff textiles and unsuitable environments. As a result, they may opt for using a dryer, which contributes to pollution.
Overall, while air-drying clothing and linens can be a simple and cost-effective method, it is important to consider the potential impact on pollution. By understanding the environmental consequences, individuals can make informed decisions and explore alternative options, such as using dryer sheets and fabric softeners or advanced filtration systems in tumble dryers, to reduce their impact on the environment.

Don't carpool, bike, or bus
If you want to contribute to air pollution, one of the best ways to do so is by avoiding carpooling, biking, or taking the bus. Cars produce about one-third of all air pollution and one-fifth of all greenhouse gas emissions in the US, so driving alone is a great way to ensure you're doing your part to pollute the environment.
When filling up your vehicle's fuel tank, ignore the click and keep filling to release extra dangerous fumes. Refuel during the hottest part of the day to further increase air pollution. If you must turn off your engine, make sure to do so in a well-ventilated area to release those lovely emissions.
Taking public transportation, biking, or carpooling reduces vehicle emissions and improves air quality, so it's best to avoid these options. Driving alone also has the added benefit of making it difficult to see and talk to people in your neighborhood, isolating you from your community and reducing your stress levels and productivity.
Biking is a healthy option that can save you money and help the environment, so it's best avoided. It can be a great way to squeeze in physical movement and improve your physical and mental health, but that's not what we're aiming for here. So, skip the bike and hop in your car instead!
Finally, carpooling is an easy way to reduce pollution and save money, but it's not ideal if you want to maximize your environmental impact. With carpooling, you can also take advantage of free carpool parking permits and save on fuel costs, but these benefits come at the cost of reducing air pollution. So, if you're committed to polluting, steer clear of carpooling and opt for driving alone whenever possible.
