There are other methods becoming more widely available In the US too such as Aquamation (alkaline hydrolysis) which yields similar remains like ashes you can spread and human composting (https://recompose.life/) which don’t emit fossil fuel emissions.
Not for everyone, sure, but I wanted to be composted. I liked that I would become a cubic yard of nutrient rich soil in about 30 days and will be utilized for forest restoration.
The mushroom shroud that breaks you down is also super cool but was pretty out of my price range.
Read The Indifferent Stars Above and Island of Sea Women and try saying that ignorant shit.
