caused: African leaders wanted a source of income so they turned to selling their own people (Now these were mostly Nigerians). The Europeans would just take them since Africa was already impoverished and they could not defend themselves

Effects: the slave trade caused wars and slave raids that brought about additional deaths, as well as environmental destruction. Got this from: http://15minutehistory.org/2012/12/03/episode-6-effects-of-the-atlantic-slave-trade-on-the-americas/
