Perhaps Briar? I keep wanting to try it, but don’t have contacts that also do. It runs offline through Bluetooth and WiFi direct as well as online through TOR.

German environmentalist Robinga Schnögelrögel recently talked about the shifting baseline syndrom, and he gave an example of how bad it is. He read a primary source from 1858 that talked about the biodiversity back then: Butterflys were described as “everywhere”, hundreds on every meadow. A type of mayfly (ephoron virgo) hatched in rivers and congregated above, making it look like a snow flurry. The next day their dead bodies would cover the river banks, which farmers picked up by the wheelbarrow to use as fertilizer and feed to their pigs. Hence ephoron virgo’s German name “Uferaas”, meaning shore carrion.
