We are experiencing this first-hand right now in South Africa. The third world can and has to grow, in harmony with the limits of nature, because the third world is not yet industrialised. Africa is suitable to thrive in the improved version of the free market economy.
Many tribes still live off the land which they occupy.
The African people are still close to nature. They kept an intimate contact with nature, because they can still grasp nature with all their senses. If the African people so decide, they can develop the tools and techniques, with which they procure themselves a livelihood, to produce on an industrial scale, while staying in close contact with nature. It will be in the interest of the industrialised world to co-operate in the research and development of the technologies to achieve this progress, in, almost, pristine nature. The research to develop the technologies that can be used both to develop an eco-industry and to ecologise current industry, can be shared.
