Ever wished Minecraft had real consequences for all that coal you burn? Pollution of the Realms Mod brings environmental awareness into your world by simulating carbon and sulfur emissions from fuel-burning sources. Blocks of pollution rise into the sky, form smog clouds, and — if left unchecked — poison your crops, sicken your animals, and slowly suffocate anyone caught in the haze. It's a compelling gameplay layer that turns resource management into an environmental balancing act.
Key Features
- Realistic emission blocks — Carbon and sulfur blocks spawn around fuel-burning sources at varying density levels, creating a visible representation of pollution spreading through your world.
- Dynamic smog clouds — Emissions rise and accumulate into pollution clouds overhead, reducing visibility and darkening the sky as conditions worsen.
- Tiered health effects on players — Pollution percentage triggers escalating debuffs: Mining Fatigue above 20%, Hunger above 40%, Weakness above 50%, Slowness above 60%, Poison above 70%, Nausea above 80%, and lethal Wither above 90%.
- Environmental impact on wildlife and crops — Animals, trees, and crops are all affected by pollution. Animals born in polluted chunks suffer permanent base health reduction.
- Suffocation mechanic — Standing inside emission blocks without protection leads to suffocation and death, making polluted areas genuinely dangerous.
- Hostile mob spawning boost — Carbon blocks reduce light opacity in the area beneath them, turning polluted zones into prime spawning grounds for hostile mobs.

FAQ
How do I reduce pollution in Pollution of the Realms?
The mod encourages players to find cleaner fuel alternatives and manage their emissions. Reducing the number of active fuel-burning sources in a chunk helps lower the pollution percentage over time.
What happens if pollution reaches 90% or higher?
At 90% pollution or above, players receive the Wither effect, which is lethal. You will also be affected by all lower-tier debuffs simultaneously, making the area extremely dangerous without protection.
Does Pollution of the Realms work with modpacks?
The mod is compatible with Forge and NeoForge mod loaders and requires ForgeEndertech as a dependency. It pairs well with tech-focused modpacks, especially those that include Advanced Chimneys Mod for extended chimney functionality.
