The ocean is teeming with a strange bacteria. A toxic gas fills the caves, and everything above ground is irradiated.
You, through some miracle or perhaps magic, are immune to all three. However, your items are not.
Life has evolved an immunity to the danger of their particular environment. Bringing items from any region to any other will quickly destroy all wildlife.
You must survive and thrive in three different environments, without taking items from one to the others.
Rules:
Rule 1: You cannot move items between regions
An item obtained in one region must stay in that region to prevent ecological destruction.
The ocean is defined as an ocean biome, below sealevel but above the sea bed.
The underground is any open area underground, such as caves or dungeons.
The above ground region is everything else.
Rule 2: Contaminated regions are fair game
If an area is a mix of multiple regions, consider the area pre-contaminated. Life there has either evolved to deal with it or died, so you can't do more damage. The area itself, along with any area within 20 blocks is fair game. Examples include surface caves, beeches and underwater ravines.
However, once an item enters that area, it is considered contaminated by all regions. That means it's stuck there.
Rule 3: Expanding a region
If you start in the ocean or above ground and dig into the ground, the new area is considered ocean/above ground. Digging a basement is fine. Just don't dig into a cave.
Rule 4: Saplings can be moved between regions
All six sapling types appear to be immune, and can be freely moved from region to region. However, they lose this immunity when they grow, so you can't move logs or leaves.
Rule 5: Items from the end and nether are clean until you take them to the overworld
The end and nether are contamination free. Once you take them to the overworld, though, they are contaminated by the region you entered. If you exit the nether portal above ground, your items are irradiated.
Since the end and nether are both quite dead, taking items there is allowed.
Rule 6 (optional): Decontamination protocol
This is an optional rule, since it makes the challenge less difficult. You can choose whether or not to allow it.
An item from the above ground area can be placed in a safe completely enclosed with iron blocks. After 18 Minecraft days (6 real life hours) the items are radiation free.
An item from the ocean must be decontaminated. This process involves building an airlock which starts filled with water and then drains when you enter it. Once the water is drained, splash potions of poison must be dropped from a dispenser to kill any bacteria.
An item from underground must be burned to ignite any swamp gas. This involves holding the item and then being completely submerged in lava. Fire protection is strongly advised.
