cow dung and ghee to produce oxyzen
Cow is the only animal, which emits major amount of oxygen as its lungs doesn't absorb oxygen with much efficiency. It is used in Agnihotri. If one spoon of pure ghee is poured on the burning cow cakes dung (fuel) then they can produce a good amount oxygen, therefore ghee made with cow milk is used in sacrificial fires and havans. What can be the better method to deal with the air pollution?
