Piktochart on HART (Halt All Racist Tours)

This is my piktochart about HART which was a protesting group throughout the time of Apartheid. This was a New Zealand organization and they were lucky to have John Minto (my form teacher!) to lead them throughout this time. We are currently learning about racial equality and apartheid. This covers Human Rights, Apartheid, White and Black segregation and all the nasty events that had happened in our horrid past. We are learning this so we know all about this racial equality rules and what had happened in our history so we know what has changed and what is still to come. We learned this by watching the movie The Power Of One Which gave us vivid ideas on what apartheid was like for the Black South-Africans. My question that I have is why were the whites and blacks segregated? what if it was the other way round?
