Social change activists are needed for altering traditional norms and are needed as a catalyst to rekindle a certain view, idea or value. Mahatma Gandhi, Dr Martin Luther King and Malala Yousafzai are examples of individuals who had and went against traditional norms. Leadership is the ability to become a leader while leading a group of people or organization. Social change is when you change the structure and size of social systems and it happens sometimes unknowingly while most of the time it is done intentionally. Without people like Gandhi, King and Yousafzai the world would most certainly be in a different state. These individuals have created a change which has helped people all around the globe and also helped the world to become more in unity and harmony.
