The ocean is an excellent example of a shared resource that can easily be abused and degraded because it’s shared by many different nations. No single authority has the power to pass laws that protect the entire ocean. Instead, each nation manages and protects the ocean resources along its coastlines, leaving the shared common space beyond any particular jurisdiction vulnerable to pollution. Throughout the world’s oceans, garbage has begun to accumulate in the center of circular currents, or gyres. These giant patches of ocean garbage occur because many different countries allow solid waste to enter the oceans from land or ships. Destruction of ocean ecosystems because of garbage, especially plastic pollutants, is likely to affect every person on the planet as these pollutants cycle through the food chain. The above scenario is an example of _____.
a. a collective action
b. problem collective
c. problem-solving sustainable development
d. the pollution-inaction disaster

Problem collective, or a Collective action problem is a shared problem that can be cooperated and solved collectively by those who are affected by it but they fail to do so because of their "Conflicting Interests."

Conflicting interests means that the goals of each country/individual are different and in order to come to a productive conclusion, each nation/individual has to make sacrifices and changes to their objectives. But as it doesn't happen, the problem persists and gets worse eventually.
