What is the theory that a growing population will meet its needs?

The theory that a growing population will meet its needs is often associated with the concept of "population optimism" or "Cornucopian theory." This perspective suggests that human innovation and technological advancements will enable societies to find solutions to resource constraints, allowing populations to thrive despite increasing numbers. Proponents argue that as challenges arise, humans will adapt and create new resources or more efficient ways to use existing ones. Critics, however, caution that this view may overlook environmental limits and sustainability concerns.
