[Stoves] Stoves Digest, Vol 2, Issue 26

Philip,

   Outdated statistics. Not 1.4 million.  The W.H.O. quotes 1.6 million 
every year.

  Indoor air pollution and health

      Scope of the problem

"More than half of the world's population rely on dung, wood, crop waste 
or coal to meet their most basic energy needs. Cooking and heating with 
such solid fuels on open fires or stoves without chimneys leads to 
indoor air pollution...
Exposure is particularly high among women and children, who spend the 
most time near the domestic hearth./*Every year*/, *indoor air 
pollution* is responsible for the death of *1.6 million* people - that's 
one death every 20 seconds."
