In the context of W. W.

Because people start to generate more income from trade and production surpluses, there is greater entrepreneurship and industriousness. Societies begin to trade primary products with other nations. At present, the notion of sustainable development is dominant in the literature and in development spheres like NGOs and International organizations. This entails some controls of population pressure and efficient, renewable uses of environmental resources.
