Answer:
an externality, market failure
Step-by-step explanation:
The company in this case has a par production because the cost to the seller is the same as the benefit to the buyer. Now the company is dumping chemicals that are affecting people in the community that do not patronise them. The chemicals cause poisoning of wildlife and harms health of nearby residents.
This characterised an externality that is the dumping of chemicals affecting the residents in the community.
It is also a market failure because while the company is not making profit they are also harming the society where they operate.
