Answer:
Individual
Step-by-step explanation:
The answer is "Individual" approach.
Ethical dilemmas refers to a state of mind of a person when a person or group of persons is not able to decide ethically on the positive or negative effects of an act.
The local livestock farmers allowed the manure nutrients to flow into the local lake from where they feeds. For a short term it will not cause any harm to the farmers live and their family members but as time passes, the lake will be very much polluted and the water will not be fit to be used by them. Thus in the long term allowing the manure to runoff to the lake will affect the people's health.
Thus the farmers will act ethically and think logically to avoid harming others in the society by not allowing the runoff of the manure nutrients to the lake.
This reflects the individual approach of the farmers in deciding ethical dilemmas.
Thus the answer is "Individual".
