Pollution is considered an external cost when it has harmful effects borne only by the people who purchase the products that cause the pollution the cost to the environment is not reflected in the price of the products that produce the pollution it has a significant impact on the consumer's decision to buy a product that pollutes it is a hidden cost that would result in a greater demand for the product if the consumer were aware of the hidden cost it is produced in the external environment by a malfunction in the operation of the product

the cost to the environment is not reflected in the price of the products that produce the pollution
