Common goods are resources that are shared by a community and are available to everyone, but they are limited in supply. Examples include clean air, water, and public parks. These resources can be used by individuals without direct payment, but overuse can lead to depletion or degradation, making it essential for communities to manage them responsibly. The concept of common goods highlights the importance of cooperation and sustainable practices. When people work together to protect these resources, they ensure that future generations can also benefit from them. Effective management often involves regulations and community agreements to balance usage and conservation.
