This monograph is predicated on a combative decolonial-Afrocentric ecophilosophy of science of nature and humanity. It is rigorous and comprehensive scholarly account of how nature has been colonised and turned into a natural resource available for the Cartesian subject in charge of the capitalist system to humanity's ad infinitum exploitation, with serious consequences for sustainable developmentalism. There is no doubt that this ground-breaking monograph will challenge scholars and irritate new critical thinking on developmentalism, which takes into account the threat of human activity on nature, the environment and ecology. It is a bold presentation of thoughts that will provoke other researches. Away from the tempting positionality of degenerating into nostalgic and romantic traditionalism versus fast-lane modernism, the author consistently problematises the complex issues through deployment of multidimensional thinking, the relationship between human beings and nature, and how technology, development (in the colonial sense) and colonial expansionism have objectified nature, sucked it dry of its content, and reduced it to the status of raw material for the production of man's success.
