What is a conscious change in the world by man called?

A conscious change in the world by man is called an intervention. Interventions are intentional actions taken to bring about change in a social system, such as a community, an organization, or a nation. They can be implemented to address a wide range of social issues, such as poverty, inequality, environmental degradation, health disparities, and access to education. Interventions can involve a range of strategies, including policy changes, economic incentives, and educational campaigns. They can also involve direct action, such as providing services, establishing partnerships, and engaging in advocacy. Interventions can be designed to target specific individuals, groups, or communities, or they can be designed to have a broader impact. Ultimately, the goal of interventions is to create positive change in the world by addressing the root causes of social issues and promoting long-term, sustainable solutions.
