This question comes with my thoughts on a swamp city, but is open to thoughts about any biome.
We know cities are their own form of ecosystem, and all ecosystems must have decomposers. Right now, people are always fighting against them and hating them, which I understand–I also don’t like seeing cockroaches, especially inside my house! And fungi can be good decomposers, but all I ever see is mold that can make me sick in my bathroom.
But I understand we need them. I like to think once there’s better protection for actual native species, more than just the hardiest decomposers will also thrive. IDK, what do we think? Is it fair to hope for different decomposers that gross me out less, or am I being a bully? Do we need to have more purposeful conservation to introduce native decomposers and eliminate invasive ones, or do we think it will happen naturally as native decomposers follow other native species? In a theoretical solar punk paradise city, do I have to accept molds in my house?
Sure, but dead plant parts should be outside your house when decomposing. Same with food waste. Economy of scale still exists with municipal composting.
