# \ud83c\udf3f Gaia\u2019s Breath<\/p>\n
A Fabric mod that makes the **natural world evolve on its own**.<\/p>\n
Grass spreads, flowers sprout, trees regenerate, metal weathers, wood ages \u2014 Minecraft\u2019s ecology becomes **alive, gradual, and configurable**.<\/p>\n
—<\/p>\n
## \ud83e\udded Overview<\/p>\n
> The world breathes, grows, and heals over time.
\n> Without player input, nature **reclaims** barren land and balances overgrowth,
\n> creating a living landscape that changes as you explore.<\/p>\n
### Main Features
\n– **Vegetation propagation**: short grass spreads, may become **tall grass**, and **wild flowers** can appear.
\n– **Tree renewal**: **saplings** can pop near trees, letting forests naturally expand.
\n– **Natural path formation**: player footsteps gradually **wear down grass** into **coarse dirt** and **dirt paths**, which can slowly recover over time.
\n– **Charcoal from burned wood**: when wood blocks are **burned by fire**, they can **drop charcoal** instead of disappearing completely.
\n– **Fully configurable** via an in-game screen (tick budgets, growth chances, moss spread, path erosion, and more).
\n– **Server-friendly**: all updates are **tick-limited** and distributed across chunks to prevent lag spikes.<\/p>\n

## \ud83c\udf31 Natural Growth<\/p>\n
### Vegetation Propagation
\n– Grass blocks may receive **short grass** over time.
\n– Short grass can convert to **tall grass** based on probability.
\n– **Flowers** occasionally generate in suitable spots (low density, natural feel).<\/p>\n
