A pledge is a solemn promise or commitment to do something or uphold certain values. It can be made by individuals or groups and often involves a public declaration. Pledges are commonly used in various contexts, such as charity, environmental initiatives, or personal goals, to encourage accountability and inspire action. In many cases, pledges are part of campaigns or movements aimed at raising awareness or fostering change. For example, people might take a pledge to reduce their carbon footprint or support a specific cause. These commitments can help build a sense of community and motivate others to join in.
