There's biology in everything, even when you're feeling spiritual.
- Helen Fisher

Human welfare is the core of subjective ethics. It simply means that the scientific and technological advancements ultimately aim at the welfare of humans. Having said that, biology itself is the branch of science that not only studies morphology, anatomy, physiology, genetics, and metabolism of living beings but also aims at improving, innovating and carving new niches to bring about fundamental changes in the welfare of humans. Biology and human welfare began right from human civilization. Biology and human welfare are exemplified by the domestication of plants and animals, making of cheese and curd, brewing of alcohol and the list can continue to eternity! Agricultural practices, food processing, and diagnostics have brought socio-cultural changes in human communities. Hence, it is essential for us to understand the very basics of biology and human welfare along with exploring the future possibilities.

Introduction to Biology and Human Welfare

From the perspective of NEET biology syllabus, the chapter of biology and human welfare encompass a wide variety of topics that account for an approximate 5% weightage in the NEET exam. Now, here is the point where most of the aspirants make a grave mistake! The weightage does not seem quite lucrative and so the concepts of biology and human welfare are left to be studied for the last moment. You should understand that easy and interesting chapters like biology and human welfare increase the chances for better scoring. Hence, they are not supposed to be ignored. Rather, they should be taken as goody-bag in the syllabus!

The application-based concepts are well defined in the eighth unit of the NCERT textbook for class 12. We shall make it our base of studying and understanding by correlating the various topics of biology and human welfare mentioned in the NEET biology syllabus.

Notes on Biology and Human Welfare

Let us explore the various topics of the chapter biology and human welfare along with understanding their practical utility and importance from the NEET exam perspective.

1. Human Health and Diseases: Since time immemorial, human health has intrigued the intelligence of philosophers and thinkers. Earlier, health was the component of physical well-being only. The Greeks like Hippocrates as well as Indian Ayurveda system of medicine asserted health to be the balance of certain ‘humour’ in the body. However, with the advent of scientific discoveries, like the circulation of blood by William Harvey, that establish more than just ‘humour’ balance, these notions changed and health began to expand its horizon beyond physical well being.

Presently, the World Health Organization (WHO) defines health as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." As a consequence, the biological improvisations are made with this holistic view of health. Therefore, in order to achieve ‘healthy’ human populations across the globe, it is crucial to realise the threats to health and this is the essence of the chapter human health and diseases. Isn’t fascinating to read such an impactful topic for your NEET preparation?

Strategies for Enhancement in Food Production: As the holistic understanding of health progressed and improved the health quotient in the human population, the life expectancy increased which resulted in pressure over the existing sources of food. Therefore, enhancement of food production also became the component of biology and human welfare. Biological principles as applied to animal husbandry and plant breeding have a major role in our efforts to increase food production. This chapter of biology and human welfare offers un understanding of such techniques.

Let us understand the make-up of different strategies used for the enhancement of food production:

  • Animal husbandry: Dairy Farm Management, Poultry Farm Management,

  • Apiculture
  • Fisheries
  • Plant breeding: Green revolution, Indian hybrid crops, Plant Breeding for Disease Resistance, Plant Breeding for Developing Resistance to Insect Pests, Plant Breeding for Improved Food Quality,
  • Single-cell protein
