Parks confer many external benefits on society: open space, trees that reduce pollution, and so on. Therefore, the market equilibrium quantity of parks is not equal to the socially optimal quantity.

Confused and unsure how to solve properly
Parks confer many external benefits on society: open space, trees that reduce pollution, and so on.
Therefore, the market equilibrium quantity of parks is not equal to the socially optimal quantity.
The following graph shows the demand for parks (their marginal private benefits), the supply of
parks (the marginal private costs of producing them), and the marginal social benefits of parks,
including both the marginal private benefits and external benefits.
Use the black point (plus symbol) to indicate the market equilibrium quantity. Next, use the purple
point (diamond symbol) to indicate the socially optimal quantity. Finally, use the grey polygon
(star symbol) to indicate the area representing market failure.
