The document discusses "blood diamonds" which refers to diamonds mined in war zones and sold to fund violence and oppressive regimes. Specifically, it notes that in Sierra Leone in the 1990s, rebel groups took control of diamond mining cities and committed atrocities like amputating limbs and killing over 50,000 people to gain control over the diamond trade. The document explores how "blood diamonds" have negatively impacted parts of Africa through widespread death, refugee crises, and human rights abuses like child labor in mines.
