(So, the charcoal stove uses much less coal and it emits many times smaller amounts of toxins in the air). And the cookstove program, and the sustainable charcoal programs that have been in that area have been making a profit and operating successfully since the 1970's. <o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'> In addition to that, there are already improved agriculture and re-greening programs that are working in that area long enough so that the farmers are seeing a lot of improvement in their soils, or in their sacks of soil that they use in the city to grow food.
