In the globalized era, people live in a healthy and comfortable environment. However, some communities have found themselves in a precarious situation due to their inability to meet their basic needs, which are essential for their daily survival. The Birhor (PVTGs) community is one of the very backward tribes; they are still like primitive humans. This paper investigates the lifestyle challenges of the primitive tribe of 'Birhor' in the Purulia district. The investors are trying to understand their overall socio-cultural perspective and education. Who should improve sustainable development? The ethnographical method introduced investors to the qualitative research approach. Data collection involved the use of personal interviews and participatory observations. Consequently, this study connected investors to important issues and solutions regarding the barriers to formal education and sustainability development.
