Professor Wangari Maathai is the first African Woman to be awarded the Nobel Peace Prize in 2004 for her involvements in saving the environment through the Greenbelt Belt Movement. She was a Kenyan politician who served s an assistant minister for natural resources and environment between 2003 and 2005. There exist many moral theories that Maathai employed, however, the ethical theory that fits Maathai is the Unitarianism theory. Deontological theory least suits her personality. This theory fits the Professor because it argues that there is no rule or law that is intrinsically wrong or right.

According to Boylan (2009), ethical theories define the manner in which a professional should conduct him/ herself. Professor Maathai employed the Unitarianism moral theory because the in her efforts to conserve the natural environment; mainly natural forests, she advocated for the eviction of investors and individuals who had mainly encroached into the public natural forests. She advocated for sustainable development. Through utilitarian ethical theory, Professors Maathai advocated for the eviction of the few who had acquired the public forestland for the benefit of the majority Kenyans through conservation of the natural ecosystem. Her achievement to evict prominent people from the forests was faced with a lot of resistance from the tyrannical President Moi government of the time. Deontological ethics theory advocates adherence to the natural laws and does not focus on the consequences of an action unlike the case of the Unitarianism ethical theory. Deontological theory is universalizable (Trevino & Nelson, 2011). Therefore, this theory least fits the character of Professor Maathai because it denounces eviction of people or destruction of investors property because the ensuing consequences in terms of the loss incurred.

Professor Maathai political success is mostly attributed to employment of the Unitarianism ethics theory. Through the theory, most of the government forests have been preserved, Green Belt Movement has continued to advocate for sustainable development.  Deontological ethics theory does suit her character because she mainly focused on the consequences of her actions.
