Rangers and Ranger Stations

I love Minecraft, but I feel like it is really hard to replant what you take from biomes you have visited. I think it would be great to have a renewable way to do this. Now, what if the way you sustainably chop wood and mine materials is with someone else who cares about it just as much as you? The Ranger would spawn in a new structure that can spawn in any biome, a small house made of materials found in that biome. The ranger station has a bed, and a ranger's desk, which is a new job block. The ranger does not count as a villager and cannot be integrated into villages or trade with villagers. He can be attacked by illagers, zombies, zoglins, wardens, and the wither, but he doesn't leave his station, so he will typically survive. They will take emeralds in return for biome-specific resources to restock the plant and animal life, such as sweet berries, saplings, dead bushes, cacti, grass blocks and mycelium in case you've killed off all the ground cover. If you give him resources from other biomes (E.G. you give a taiga ranger oak wood), he will trade for it in return for emeralds. In addition, he will give you emeralds for planting naturally occurring plants in that biome. (Bonemealing doesn't count) (Planting trees will be a 1/10 chance of receiving an emerald, but only after it has grown fully; ferns and flowers 1/20, tall grass 1/50, and grass blocks 1/100. If you place stone or stone variants found in the biome, it is a 1/500.) Thank you for reading my idea!
