Earth Biome
From Project Rebearth
The Earth Biome is one of four biomes in Project Rebearth. It covers arid, grassland, and dry regions of the world, where 
Earth is the dominant resource. Settlements in the Earth biome benefit from exceptionally low 
Wood upkeep on housing and excel at 
Glass production through abundant Earth supply.
Overview
[edit]The Earth biome is associated with dry and open landscapes. Earth serves as both the primary resource and the construction material for all buildings in this biome.
Construction
[edit]Buildings in the Earth biome cost Earth as their primary resource. For example, a Shack costs 35 Earth, a Cabin costs 80 Earth, and a Town Hall costs 1,000 Earth plus 500 
Stone, 10 
Tools, and 20 Glass.
Housing Upkeep
[edit]The Earth biome has a significant advantage in housing upkeep since Wood consumption is roughly one-tenth of other biomes. A Shack consumes only -0.1 Wood per day compared to -1 in the Wood Biome and Stone Biome, or -2 in the Arctic Biome. 
Food consumption remains the same across all biomes.
| Housing | Wood/day (Earth) |
Wood/day (Wood/Stone) |
Food/day
|
|---|---|---|---|
| Shack | -0.1 | -1 | -1.5 |
| Hut | -0.15 | -1.5 | -2 |
| Cabin | -0.2 | -2 | -2.5 |
| House | -0.25 | -2.5 | -4 |
| Residence | -0.3 | -3 | -5 |
| Villa | -0.35 | -3.5 | -6 |
Resource Production
[edit]All biomes have different production rates per biome and the table below compares key building output across all. Values in bold indicate the highest rate for that building in the Earth Biome.
| Building | Resource | Wood Biome | Stone Biome | Earth Biome | Unit |
|---|---|---|---|---|---|
| Woodcutter | Wood |
30 | 15 | 5 | /day |
| Nursery | Wood |
5 | 2 | 1 | /day |
| Tent | Wood |
5 | 3 | 1 | /day |
| Saw | Wood |
20 | 20 | 20 | /day |
| Quarry | Stone |
0.01 | 0.03 | 0.01 | /m²/day |
| Stone Crane | Stone |
20 | 30 | 10 | /day |
| Claypit | Earth |
0.01 | 0.01 | 0.04 | /m²/day |
| Clay Crane | Earth |
20 | 10 | 30 | /day |
| Iron Mine |  Ore |
40 | 100 | 60 | /day |
| Foraging Hut | Food |
5 | 5 | 3 | /day |
The Claypit produces 0.04 Earth per m² per day in the Earth biome, four times the rate in other biomes. The Clay Crane produces 30 Earth per day, also the highest of any biome. This abundance of Earth makes the Earth biome ideal for Glass production via the Glassworks, which consumes -50 Earth per day to produce 5 Glass.
The Woodcutter produces only 5 Wood per day, the lowest of all biomes. However, the Saw produces 20 Wood per day regardless of biome, providing a consistent alternative at the cost of -0.2 Tools per day.
The Foraging Hut produces 3 Food, 1 Wood, and 2 Stone per day in the Earth biome, offering a small but diversified resource output.
Strategy
[edit]The Earth biome's low Wood upkeep makes it the most efficient biome for large-scale housing, allowing settlements to support large populations with minimal Wood consumption. However, its low Wood production means players must invest in trade or multiple Woodcutters to sustain building construction and Tools production.
While the Woodcutter produces only 5 Wood per day in the Earth biome, the Saw produces 20 Wood per day regardless of biome, making it an effective way to supplement Wood output. The trade-off is that the Saw consumes -0.2 Tools per day.
The biome's strength in Earth production makes it a natural hub for Glass manufacturing via the Glassworks, which can be traded to other settlements. Combined with the Claypit and Clay Crane, Earth biome settlements can generate large surpluses of Earth for export.
