The word science came from the latin word "Scientia" which means knowledge. Science is the search of reasons for different things on the process of knowing the truth. Science can be defined as the systematic study based on the facts, known by actual observation, experimentation, experiences, analysis and conclusion.
Biology is one of the branches of science. The word Biology is formed by two greek words i.e. "Bios" means life and "logos" means study. Literally, biology is the study of life. It is developed to study living organisms. It is an exceedingly broad and diverse subject which helps us to understand life process and reveals the secret of life:
Human beings are the most intelligent organism due to the capability of thinking and understanding. For human, study of science has dual purposes. Firstly, they gain scientific knowledge. Secondly, they apply the knowledge for human welfare. On the basis of practical application, scope of biology in context of Nepal can be discussed in the following points;
Biology gives knowledge about the useful and harmful plant. So, the farmer can get better pest free crops.
Biology provides the knowledge to maintain good health by following a proper food, exercises, good habits etc.
Several pathogens cause different diseases. The habit, habitat, structure, life cycle etc of such pathogens can be studied in biology. So, we can be away from different diseases to a considerable extent.
Most of the industries are based on the products of plants and animals i.e jute, rubber, gum, sugar, leather etc.
Conservation of flora and fauna
Biology helps the scientists or researchers to conserve endangered flora and fauna.
Rearing of animals for food, watchman-ship, agriculture, transportation etc is an old practice done by man. Biology gives an idea to keep such animals in a systematic way.
Entertainment or Aesthetic value
Rearing of animals and preserving plants are done by the human for entertainment as well i.e. zoo, circus, aquarium, park, garden etc.
The products obtained by the rearing of animals and planting can be sold in a market which gives financial aid. Tourist visits in Nepal to entertain with natural resources, wild lives, medicinal plants etc. By exposing flora and fauna, the country can raise its economic status.
The concept of biology is essential in veterinary science, dairy science, pisciculture, apiculture, biotechnology, biophysics, biochemistry etc. Biology accepted the challenges given by the world regarding food, population, and disease with solutions i.e. new technology in agriculture, family planning and medicine.
