Confusing

• "objectivity"-When people regard human beings, nature or the earth as objects, that is to say they are thinking of the issues of ecology and environment something happening in distant. Latour affirms that people need to shift to "subjectivity".
• "subjectivity"-"Earth is quaking anew ... because it is being transformed by our doing. (P4)" Human beings have become the subject of this planet. The earth is not moving but they are moving the earth. Thus they are the cause of this environmental destruction.
•  "animate", "deanimate"... "semiotic", "ontologic"-I could not understand what Latour was saying at the rest of the part from when he began to use these words. He cliams that before the concept of "Anthromorphism" came up, "angelo-", "phusi-" or "bio-morphism" had already existed. This is the semiotic propositon and he follows it by ontologic proposition and insists on the relation between "existence" and "meaning". What does he want to tell the reader here?

I could not catch the point of his argument. What does he want to say? What does he want to agitate?
