This article elaborates the conditions as well as four potential modes of the ecological problem: (1) The mode of the absolute minimization of the ecological problem: minimum population plus minimum Gross Domestic Product (GDP), which is characterized by the quantity of destruction being less than the quantity of natural rehabilitation of an ecosystem. This mode is the poorest mode with minimum change. (2) The mode of the relative minimization of the ecological problem: minimum population plus maximization of GDP, which is (...) characterized by the quantity of destruction being less than the quantity of both natural rehabilitation and human rehabilitation of an ecosystem. This mode is the best mode with minimum change. (3) The mode of the relative maximization of the ecological problem: maximization of population plus minimum GDP, which is characterized by the quantity of destruction to the ecosystem not being offset by the quantity of human rehabilitation. An example of this mode is an underdeveloped district with vast population and limited farmland. (4) The mode of the absolute maximization of the ecological problem: maximization of population plus maximization of GDP. This is characterized by the continuous increase of the quantity of destruction beyond the quantity of both natural rehabilitation and human rehabilitation of the ecosystem. Its final outcome is the collapse of the ecosystem and a catastrophe to human beings. (shrink)
