...i think you would also have to look at the other impacts of both practices (sugar cane and honey production). yes, bees take in o2 and out co2...but planting/harvesting sugar cane simply displaces other kinds of vegitation that would be growing in the fields otherwise...probably a near zero sum (although sugar cane does fix carbon more efficently than many plants). the keeping of bees, on the other hand, increases the the pollination of plants in the immediate vicinity. if the presence of bees increases the ammount of vegitation (via increased fertilization), does this increase in co2 uptake balance out the co2 the bees produce? i don't know the answer, but i don't think it's so simple. deknow ****************************************************** * Full guidelines for BEE-L posting are at: * * http://www.honeybeeworld.com/bee-l/guidelines.htm * ******************************************************
