Human beings interact with their physical environment with the help of technology:

(i)Technology indicates the level of cultural development of society. Human beings were able to develop technology after they developed better understanding of natural laws.

(ii)For example, the understanding of concepts of friction and heat helped us discover fire. Similarly, understanding of the secrets of DNA and genetics enabled us to conquer many diseases. We use the laws of aerodynamics to develop faster planes.

(iii)In the early stages of their interaction with their natural environment humans were greatly influenced by it. They adapted to the dictates of Nature. This is so because the level of technology was very low and the stage of human social development was also primitive.
