Milk production requires the use of millions of cows. Cows release methane gas and waste piles that can cause major pollution problems. Is there too little, too much or the correct amount of milk produced from a socially optimal perspective? Briefly explain your answer. Support your explanation by drawing a graph representing the market for milk that correctly identifies private and social marginal benefit and marginal cost curves along with the market equilibrium price and quantity versus the socially optimal equilibrium price and quantity. Also, identify any deadweight loss in the graph if any.
