[Stoves] How Can Blockchain Technology Help Fight Air Pollution

[Nikhil Desai]

Crispin:

Whose target, for what service standard and what objective.

The argument that Tier 5 cookstoves would miraculously eliminate all unsafe
PM2.5 exposures and infer quantifiable health benefits to current
generation is not intelligent.

Environmental health turned into such fundamentalism is .. well, we know
what fundamentalist cults do.
