To "reduce" means to make something smaller or less in amount, size, or degree. This can apply to various contexts, such as reducing waste, which involves minimizing the amount of trash produced, or reducing expenses, which means cutting costs in a budget. The goal of reduction is often to improve efficiency or lessen negative impacts on the environment. In everyday life, people can reduce their consumption of resources, like water and electricity, to promote sustainability. For example, using energy-efficient appliances can help reduce energy usage. Similarly, practicing recycling can reduce the need for new materials, contributing to a healthier planet.
