Answer:
Less air pollution
Step-by-step explanation:
It is likely that one of the reasons why air pollution is so common nowadays is because there is no regulation that grants ownership rights on the air. This means that no single person or entity owns the air. This phenomenon is known as the "tragedy of the commons." The concept states that when resources are shared by many users, these tend to act according to their self-interest and against the common good, which leads them to deplete or spoil the resource.
