The marginal external cost curve suggests that marginal profits are decreasing as it climbs. Consequently, when the optimal price rises, the ideal quantity declines.
Productivity declines when one production element rises while the others stay the same. A declining marginal return is what this is. The marginal external cost of pollutants increases with the amount of plastics in this scenario, leading to optimal price increase and optimal quantity decrease, which causes a decline in productivity levels. This is defined as the additional benefit to society as a whole from each additional unit of pollution. The benefit chosen is the Marginal Social Benefit of Pollution, if all the costs and/or benefits associated with pollution were fully listed. We refer to this situation as private benefits.

A marginal social benefit is defined as the following added to: External benefits + a small private benefit.
