The elements of socio-cultural aspects like social norms, values, social systems, traditions, and practices directly affect human life. They developed during the social evolution of human beings at different places. There are many cultural systems affecting the health of people. Some ethnic groups have a system of taking alcohol during religious occasions. Such systems affect health adversely. Some religious days are celebrated with compulsory bath in the morning. Such cultural traits are helpful to promote the healthier behavior of people. System of preserving natural resources like rivers and certain trees (For example Peepal, Tulsi, etc). contribute effectively in the conservation of natural resources. Socio-cultural practices are influenced by the environmental factors around us and their utilization, They are mostly associated with locally available plants, animals, rivers, and other natural resources. Similarly, the environment is also affected by these practices. In some cultural days, we have a trend of overeating and in some, we remain hungry without taking even a drop of water. Both practices harm our health because we need food in a limited amount at regular intervals.
Living things, including plants, animals, and micro-organisms, constitute the biological aspect of the environment. There are many kinds of biological components that have created wide diversity among the biotic components. Biodiversity is an important determinant of population distribution and density. A human being is also one of the components of biodiversity. It depends upon several other biotic factors, including plans and animals. Human survival is possible only with the consumption of biotic resources of the environment. Food, clothes, furniture, fresh air, availability of water, etc. are influenced by the living things around them. On the other hand, human health obviously determines the population size of its own.
The population size, directly or indirectly, influences the environment. In this way, health, population, and environment are interrelated on the basis of biological aspects.
