2. Why are they poor? (Cause)
Rich countries/companies harvest the following raw materials in Africa:

Tea
Africans as a people may be poor, but Africa as a place is fantastically rich - in minerals, land, labor and sunshine.
Th
way of making flexible foil circuits and/or flexible flat cables (FFCs) is laminating very thin (0.07 mm) copper strips in between two layers of PET. These PET layers, typically 0.05 mm thick, are coated with an adhesive which is thermosetting, and will be activated during the lamination process. FPCs and FFCs have several advantages in many applications:
proteins, but there are (as of July 2011) no known structures of any OR. There is a highly conserved sequence in roughly three quarters of all ORs that is a tripodal metal ion binding site, and Suslick has proposed that the ORs are in fact metalloproteins (mostly likely with zinc, copper and possibly manganese ions) that serve as a Lewis Acid site for binding of many odorant molecules.
I. Introduction
1. What is E-waste?
E-waste are the reusable or reparable electronics and secondary scraps (copper, steel, plastic etc.) which are dumped by consumers rather than recycled, including residue from reuse and recycling operations.

Nowadays, we can buy electronics with cheap prices because of the competition among the electronic companies and we

Advantage 2 : Overseas Investment and Expansion
With huge reserve (US $514 bn in Sept'04), a stronger Yuan and government loosening the control on capital outflow, it will be economically rewarding to invest abroad. On the other hand, Chinese firms may desist f
