Final answer:
The size of a commons negatively affects a person's sense of responsibility due to the tragedy of the commons, where larger commons lead to less perceived impact of one's actions, causing greater potential for resource abuse.
Step-by-step explanation:
The relationship between the size of a commons and a person's feeling of responsibility for it is often seen as negative.
The concept known as the tragedy of the commons explains that as the size of a commonly shared resource increases, individual accountability and sense of responsibility tend to decrease. This is because the larger the commons, the less direct impact one person's actions seem to have, leading to a greater likelihood of abuse and overuse of the resource for personal gain.
On the other hand, smaller commons tend to encourage more stewardship and consideration for community needs, as each person's contribution or abuse heavily affects the overall condition of the common resource.
