Though Gandhi was strongly opposed to the comingling of races, the working-class Indians did not share his distaste. There were many areas where Indians, Chinese, Coloured, Africans and poor whites lived together. On February 15 1905, Gandhi wrote to Dr. Porter, the Medical Officer of Health, Johannesburg (CW. IV p.244, and "Indian Opinion" 9 April 1904):
Wakati, tunapata Uhuru Tanzania ilikuwa na ndovu waliokadiriwa kuwa takribani 350,000. Lakini, kwa sababu ya ujangili uliokithiri katika miaka ya 1970 na 1980 ilipofika mwaka 1989 kulikuwa na ndovu wapatao 55,000 tu. Ilipofikia hali hiyo Serikali ikaanzisha Operesheni Uhai iliyohusisha Jeshi la Ulinzi na kuongozwa na Meja Jenerali John Walden (ambaye sasa ni marehemu) kuendesha mapambano dhidi ya majangili.
