Sustainable development at local, regional and global scale perhaps is the most difficult task that humanity has ever faced. Central to all of the many approaches aimed at both identifying unsustainable practices and achieving sustainability, are access to scientific knowledge and its application. The great sustainability problems of the 21st century e.g., poverty alleviation, sustainable food production, clean and accessible water resources, the health of ecosystem and maintenance of biodiversity all require usable scientific knowledge as one critical component for their solution. Thus, whatever cultural, geographical, economic or environmental setting, a partnership between natural sciences and social sciences is a fundamental prerequisite for sustainable development. Hence, I had always try to use the science for sustainability approach through my organization to conserve the biodiversity to help the poor. I believe that Importance of scientific education for the understanding of sustainability issues means the effective communication about the basic principles related to the operational mechanism of different components of the environment as well as the information concerned with recent scientific research in the related fields. In Assam our diversity of natural resources is the only material basis for a stable national economy and social development. I am trying my best to work with the people to make them understand about the need of conservation of natural resources.
