Theorem about changing the macro-economic principle
It is no longer possible to ensure mankind’s survival with the macroeconomic practice of maintaining growth in the development of the economy.
That practice can be replaced with the one of preserving the integrity of Nature in the development of the economy. It is one way to ensure a sustainable development defined as “development that meets the needs of the present without compromising the ability of future generations to meet their own need”.
Only the consumer can effectively and efficiently keep the Earth in good condition, because he can spend his money on products that do not harm the environment.
Give the consumer a financial interest in maintaining ways of living that safeguard the integrity of Nature and he will do this consciously, with pleasure and out of self interest. Realizing that living in harmony with Nature is a good way of living, he will want to continue living in this way.
The macroeconomic practice of preserving the integrity of Nature is then bound to appeal to the consumer because he is interested to guide the advancement of the streams of commodities towards progressing within the green borders of Nature.
