About this project
What does Ecological add?

A mod to make the environment and its inhabitants feel more alive!
The Minecraft world is fundamentally a very boring place, everything is set from the beginning and past that, there's very little change.
This mod aims to modify the minecraft environment in such a way that it changes over time, providing some new unique mechanics and interactions between different gameplay elements. There are a lot of features that could be implemented into this mod in future - So suggestions are welcome.
What's New
Spoilers
Puddles
Puddles will spawn during the rain. They will slow you down slightly to walk through, and will spread during rainy weather.
Once it's no longer raining, they'll start to evaporate. Alternatively, you can use bottles or buckets to collect the water to get rid of them.

Improved Crops
The way crops work has been fundamentally overhauled - Grass no longer drops wheat seeds - instead, they now drop mixed seeds.
Mixed seeds most often won't grow into anything besides grass, however, they have a chance to grow into a random regular crop.
To grow crops, you'll have to find one of the following to get seeds (Or try your luck with mixed seeds):
- Wild Wheat
- Wild Potatoes
- Wild Carrots
- Wild Beetroot
The new wild crops will spawn randomly in your world, you can find them by simply exploring!
They are capable of growing on their own, over time more wild crops will appear nearby - Causing them to slowly spread.
Carrots now have their own seed type - Although you can still use carrots normally.

Growing Grass
Now, grass blocks have a chance to grow short grass above them naturally - And short grass is able to grow into tall grass.
This will often destroy crops and plants on grass blocks - So you might want to keep the grass under control around your base.
If farmland is close to grass blocks, it has a chance to start growing short or tall grass over it - Destroying your crops!

Responsive Forests
Trees can now spread! Over time saplings will grow nearby trees, allowing forests to spread over time.
Instead of just vanishing, leaves will now fall down to the ground once the parent tree has been removed.
Over time, leaves fallen on the ground will turn into leaf litter. Trees will also drop leaf litter neaby over time.
A full leaf litter block will turn the block under it into podzol after a while - Composting.
While a change to podzol, rather than directly related to trees - grass blocks will now spread to Podzol. This means that there will be small patches of grass inside of forests which are otherwise mostly podzol. As grass spreads to podzol, the leaf litter on the block will be removed.

Water Improvements
Some blocks are now able to erode while next to water:
- Deepslate -> Blackstone
- Stone & Blackstone -> Gravel
- Gravel & Sandstone -> Sand
- Grass, Podzol, Paths and Farmland -> Dirt
- Dirt -> Packed Mud
- Terracotta -> Red Sand
- Packed Mud -> Mud
Some erosion situations have a probability of producing one or more blocks:
- Coarse Dirt -> Gravel or Dirt
- Rooted Dirt -> Dirt or Moss
This process also applies to farmland - Meaning crops are unlikely to grow if there's too much water, as the farmland will erode back into dirt.

Buzzy Bees
Bees are now able to let flowers spread!
Unlike other plants spreading, the type of flower is completely random - It can be any, even those not usually naitive to the biome.
When a bee locks onto a plant to gather pollen, it has a possibility of spawning another random type of vanilla flower nearby.

What's Coming Next
These features aren't yet implemented, but are being worked on and are likely to make it to the mod, but it's subject to change!
Spoilers
Spreading Biomes (v0.4.0?)
- Under certain conditions, biomes will be able to spreadSupport
