During Bartholomeu Dias's voyage around the southern tip of Africa in the late 15th century, he primarily sought a sea route to India and encountered various trade goods. While he did not bring back a significant amount of commercial goods, his journey contributed to the European understanding of African trade, leading to increased interest in commodities like gold, ivory, and spices. Dias's expedition ultimately paved the way for future explorers and the establishment of trade routes that would enhance the flow of goods between Europe and Asia.

Well, since you didn't tell us what "these supplies" were or where "the trip" might be, we can only say "because they are needed."
