For these two reasons, plantation owners needed a vast supply of cheap workers, who could endure the difficult conditions of heat, humidity, and tropical diseases like malaria.
The best labor they found were African slaves: they were numerous, they were cheap, and they could resist tropical diseases because most of these diseases were already present in Africa.
