Factories and industrial plants are essential for producing goods and supporting economies, but they also contribute significantly to air, water, and land pollution. These pollutants can have detrimental effects on the environment and human health, causing issues such as respiratory problems, increased cancer risk, and even altering ecosystems and biodiversity. While regulatory bodies exist to control and reduce pollution, it remains a pressing issue, especially in industrial cities and regions. Understanding and addressing the pollution factors in factories are crucial steps towards mitigating their environmental and health impacts.

What You'll Learn
Pollution on the mini map
In the game Factorio, pollution is represented as an abstract "cloud" that is visible on the map if the "pollution" setting is enabled. It appears as a blocky red cloud and spreads outwards at a steady rate.
Prior to version 0.15, players could view pollution on the minimap. However, in version 0.15 and later, the option to view pollution on the minimap was removed. This change was likely made due to the clutter it caused on the minimap, making it difficult to read, especially when the minimap would turn solid red due to high pollution levels.
Some players have expressed frustration over the removal of this feature, as it was useful for scouting during the early game. However, others understand the decision, as the main map provides the same information without obstructing the player's view of their assemblers.
It's worth noting that some players have reported being able to see pollution on the minimap by pressing the Alt key to show the advanced UI, but this may vary depending on the game version and individual settings.

Pollution cloud visibility
Pollution clouds are visible in the form of smog or spore clouds, which cover industrial areas. The more the pollution, the more visible it is.
Aerosols, which are small particles or droplets suspended in the air, can come from natural sources like dust and sea salt, or artificial sources like soot. They impact light pollution and can amplify sky glow, especially on cloud-free nights. This is because aerosols increase the chance that light is scattered back to Earth. If the aerosols absorb visible light, as is typical in smog, they can reduce the extent to which clouds amplify light pollution.
Clouds are thick collections of aerosols that are almost non-absorbing at visible wavelengths, making them very reflective. Clouds amplify sky glow, particularly in urban areas, disrupting the natural diurnal cycle of light and dark, which is an important environmental factor for many species.
The impact of pollution on clouds has been studied by NASA, which found that smoke and human-caused pollution have different effects on clouds that produce rainfall. While smoke makes it harder for clouds to grow, pollution energizes their growth, but only if the pollution is not too heavy. Very heavy pollution can block sunlight and cool the ground, inhibiting cloud formation.
The effect of aerosols on cloud reflectivity is expected to have a larger influence on the Earth's albedo than the direct scattering and absorption of sunlight by the aerosols alone.

Pollution settings
To view pollution factors, you can refer to websites such as AirNow.gov, which provides air quality data for your local area, as well as state, national, and worldwide information. Another option is IQAir, which offers a World Live Air Quality Map and provides real-time air quality data and health recommendations for your location.
Now, if your query is related to pollution settings in games, there are a few discussions on the topic of pollution settings in the game Factorio. In the game, there used to be an option to view pollution on the minimap, but it appears that this feature has been removed in recent versions. Some players find this useful for scouting, especially in the early game, as you can move around while viewing the pollution levels on the minimap. However, others understand its removal, as it could clutter the minimap, and the same information can be accessed on the main map.
To view pollution on the minimap in older versions of Factorio, players could go to the options menu, open Graphics, and ensure that the third option, "Show pollution on minimap when detailed info is on," was turned on. Then, in the game, they could toggle detailed info with the Alt key.
In more recent versions of Factorio, the option to view pollution on the minimap may have been removed, and players are directed to the main map to view pollution levels. To do this, players can press "M" to open the main map and look for the black and red icon that indicates pollution.

Absorbing pollution
Natural Solutions:
- Plants and Green Spaces: Phytoremediation is the scientific term for using plants to absorb, contain, or render harmless pollutants in the soil, water, and air. Plants like spider plants, peace lilies, and snake plants are effective in removing toxins from the air, according to NASA's Clean Air Study. Urban green spaces, including parks, green roofs, and street trees, play a vital role in combating city pollution.
- Wetlands Vegetation: Plants growing in wetlands, such as water hyacinths, cattails, and reeds, can absorb heavy metals, nitates, and phosphates from polluted water bodies. Their roots act as natural filters, capturing and decomposing pollutants.
- Trees and Vegetation: Planting trees, grass, and shrubs in bare areas helps absorb rainwater, reduces runoff, and prevents soil erosion.
Artificial Solutions:
- Wet Scrubbing: This is a common method that uses a control device to separate pollutants from a gas stream.
- Sodium Alginate and Silica Fume Compound: This material, developed by researchers, combines sodium alginate (derived from seaweed and algae) with silica fume, a byproduct of metal alloy processing. It can absorb pollutants with 94% efficiency and is versatile and scalable.
- Activated Carbon: Carbon that has been heated above 600°C becomes 'activated' and can absorb polluting substances produced in industrial processes.
- Educational Programs: Organizations like the Minnesota Pollution Control Agency (MPCA) provide education, guidance, and incentives to reduce air pollution. They offer programs for businesses, cities, nonprofits, and communities to address environmental issues.
- Community Initiatives: Neighborhood cleanup days help reduce trash and create a sense of community. Proper disposal of motor oil and household chemicals is essential to prevent pollution of water bodies.
- Energy Conservation: Turning off appliances and choosing energy-efficient options can reduce emissions from coal-fired electricity plants.

Pollution and biters
In Factorio, pollution is produced by buildings involved in processing items and spreads outwards at a steady rate. This pollution attracts biters, which are hostile creatures in the game. Biters are spawned from nests and will attempt to reach and destroy the source of pollution if they are within its range. The pollution cloud is used to trigger these biter attacks, with the size of the cloud determining the size of the attack.
To mitigate the impact of pollution and biters, players can employ several strategies:
- Reduce Pollution Output: Players can reduce the amount of pollution their factories produce by increasing the use of solar power and implementing efficient modules in their miners and assemblers to cut down on power usage and pollution levels.
- Clear Nests: It is crucial to clear out biter nests that are within or near the pollution cloud. This can be done using combat spidertrons or artillery outposts. By eliminating nests, players can reduce the number of biters that spawn and prevent them from reaching the source of pollution.
- Install Radar: Setting up a radar network that covers a larger area than the pollution cloud can help players detect nests before they expand and send out attackers. Regular patrols, either on foot or using spidertrons, are also recommended to ensure early detection of nests.
- Utilize Natural Barriers: Identifying and effectively using natural barriers, such as water bodies, grasslands, and forests, can help slow down the spread of pollution. These areas have higher pollution absorption rates, especially water, which significantly slows down pollution.
- Fortify Defenses: Building walls, turrets, and automated defenses around the factory can help deter and defend against biter attacks. Laser turrets, logistics bots, repair packs, and different types of ammunition can be used to strengthen these defenses.
While it is challenging to completely eliminate pollution and the threat of biters, implementing these strategies can help players manage and reduce their impact on the gameplay experience.
