Scientific research and the development of new tools and techniques have undoubtedly improved the quality of our lives. The importance and relevance of biology to the human society and mankind in general in this respect cannot be overemphasized. Biology is also important to our everyday life because it allows human beings to better understand their bodies, their resources and potential threats in the environment.
Biology being the study of living things, helps us to understand every living organism. As a field of science, biology helps us understand the living world and the ways its many species (including humans) function, evolve, and interact. Advances in medicine, agriculture, biotechnology, and many other areas of biology have brought improvements in the quality of life.
Fields such as genetics and evolution give insight into the past and can help shape the future, and research in ecology and conservation inform how we can protect this planet’s precious biodiversity. Biology has also helped us to understand and know the similarities between plants and animals. It has also helped us to understand and know the characteristics of living things. Biology has also helped us to understand how germs work and helped us stay healthier
Biology finds application in
- medicine, dentistry and veterinary science,
- agriculture and horticulture,
- food-production industries, and
- biotechnology, which includes fields like genetic
- Engineering and hybridoma technology.
The above are some of the many career fields open to the students of biology.
Some important achievements of applied biological research include
- Development of vaccines and drugs for preventing and curing many serious diseases
- Organ transplants
- Invitro fertilization (IVF) which helps infertile couples to have children
- Production of hybrid crop plants and far animals with desirable qualities
- The use of biological pesticides instead of chemical ones in the control of agricultural pests
- The use of naturally occurring bacteria to clean up oil spills and toxic chemicals and possibly in the near future radioactive uranium wastes as well
- Production of single cell protein (SCP) by micro-organisms. This may save millions of people from dying of protein deficiency.
- Using genetically engineered microbes to manufacture at low cost, substances which we find difficult to produce such as insulin and interferon
- Using hybridoma technology to produce antibiotics.

Currently, scientists are working on many important biological issues that affect our lives These range from ways of dealing with the world’s exponential population growth and its demands to a cure for aids (Acquired immune deficiency syndrome). Exciting research is also going on the field of genetic engineering which has opened up vast possibilities such as being able to rid humans of genetic disease as well as bringing out only their best qualities.
An adverse effect of biology is the development of biological weapons. These weapons use disease causing microbes to attack. Such weapons have provoked considerable protests international internationally.
