Pollution

Pollution in Eco is caused by either Ground Pollution or Air Pollution (CO²).

Plants and trees will not grow in polluted areas, but some plants are more resistant to pollution than others.

The sources of pollution and the spread of the pollution can be inspected on the Map using layers.

Types of Pollution

Ground Pollution

Ground pollution includes water and spreads using the rules of hydrology, and "seeps" into nearby blocks.

Ground pollution is caused by:

• Tailings - A byproduct from ore processing.
• Garbage - Created when a player drops items on the ground.
• Sewage - A byproduct from Smelting at a Blast Furnace, as well as other machinery. It can be transported through Pipes.

    "Currently, pollution reduction for Ground Pollution is based on how many solid blocks are above it, every 5 solid blocks reduces pollution by 50%. For example, with 10 solid blocks above the reduction would be 75%, with 15 it would be 87.5% and so on." - Version 0.9.2

Air Pollution

Air pollution spreads through the air, and has the same effects on the fauna and flora as ground pollution, but is quick to dissipate if given time.

Trees absorb CO₂ at the following daily rates:

Birch: -0.075

Cedar: -0.075

Ceiba: -0.15

Fir: -0.075

Joshua: -0.0375

Oak: -0.15

Old Growth Redwood: -0.15

Palm: -0.0375

Redwood: -0.15

Saguaro: -0.0375

Spruce: -0.075

Air pollution is caused by:

• Smog - Smog is caused by the burning of fuels at Crafting Tables, or by the use of Vehicles. It can be transported through Pipes.

Prolonged air pollution can lead to sea level rising, which is devastating and is permanent.

Air Pollution Example

Air Pollution Spread is very aggressive. This is with a Blast Furnace and Cement Kiln venting to the same exhaust Pipe operating for about 45 mins.

History

• Beta 8.0.0, Introduced Plumbing to ECO allowing the transfer of Water and Sewage through Pipes.
• Beta 7.2.x, Introduced Pipes to transport Smog.
