Explain why acid precipitation is a source of international conflict and why international cooperation is necessary to resolve the problem.

Is a source of international conflict because, as it falls downwind, the area in which it accumulated is not necessarily the area that will be damaged. So countries must work together to reduce the problem because they are damaging one another's environments.

Iam pretty sure it is answer c. meep i hope you have a great day ^^
