The funny film showed that the contrasting worlds of the civilized area and the primitive yet calm society of the bushmen manifest an also contrasting example of worlds in terms of the equation I = P x A x T, an equation formulated to describe the impact of human activity on the environment. [where Human Impact (I) on the environment equals the product of population (P), affluence (A: consumption per capita) and technology (T: environmental impact per unit of consumption)].
In the primitive population of the Bushmen, it would be believed and manifested in the film that their human impact on the environment of the Kalahari Desert is apparently less than that of the civilized world found on the city since the living Bushmen are not too many in number, they are just about twenty or so. Being primitive, they also had a very low level of technology. They are just using soft raw materials provided by their environment, thus, they cannot produce more products, putting their affluence also on a low level.
In the civilized world somewhere in South Africa, the city, which is densely populated by busy civilized individuals (since the rise of the industrial societies equates to an exponentially increasing human population), greatly developed their technology which in return enormously aid in developing their affluence, has indeed a greater human impact on the environment of the area they are residing in South Africa relative to the primitive population of the bushmen living in the Kalahari Desert, as seen with the tall buildings, long roadways and road bridges and other landscapes that could attest to this great impact.
