Question

explain the statement "what goes under the pot costs more than what goes inside it,,?

Answer 1

This expression means the poor people in developing countries are cutting firewood because the cost of living has become very high. The poor are forced to cut wood from the forests to use it as fuel for cooking their meals. The cooking fuel in the developing countries has become more expensive than the food itself. So, the forests are being decimated.  

Answer 2

With a growing population and the pace of the global developments taking wings, the cost of food touched a new height, all time high. Amazingly, the cost of cooking-gas overtook that of food-grains, fish, meat and vegetables, thus the fuel to cook – gas, firewood and electricity – now costs more than the raw-food.
