How are health population and environment related in biological subject?
Answers
Answer:
Health, population and environment education is introduced as an integrated subject due to profound interrelationship that exists among the subject matters of these three disciplines. Any changes in one discipline directly influences changes in other two subjects. For instance, the effect of population growth lies in health and environment aspects. Due to rapid population growth, degradation of the resources takes place. Degradation of environmental resources affect in healthy living. On the other hand, controlled population creates a balanced environment and consequently, it tends to produce healthy people. Therefore, education of health, population and environment acts as supplementary of a one another. The following are the different aspects of health, population and environment which shows the relationship between them:
Physical aspect
The natural physical aspects and man- made things come under the physical aspect. Man produces different physical things to satisfy his/her needs and wants. While producing such materials people use raw materials available in their environment. Thus, the development works like construction of roads, canals, bridge, industries, etc. are the physical environment. This is the reason that the density of population is greater in places where different physical aspects are available. So, the physical aspect is especially interrelated with one other and to various aspects of health and population.
