COMPLEX LINKAGES

The two approaches mentioned above examine the same relationship but in the two the dependent and independent variable are interchanged. There are also some who do not accept separation between man and nature as logical categories. In their view, over centuries human ingenuity has constantly been working on nature, modifying it, assigning new meanings to nature, assigning new meanings to humanness itself, and redefining the relationship between man and nature. In the age of genetic engineering, using techniques of molecular cloning and transformation to alter the structure and characteristics of genes directly, how one can define the term natural? To quote:

We inhabit a triangular world of society (including human biological existence), cultivated nature and non-cultivated nature. Interactions between them are also triangular. Impacts occur (in either direction) between non-cultivated nature and cultivated nature, between society (pollution, construction, irrigation) and non-cultivated nature (earthquakes, viruses and so on) and between human biological and social existence and both cultivated and non-cultivated nature (Harvey et al., 2002,1).

Which view among the two is more conducive to study population-environment link?
