Answer:
The positive effects:
Some of the benefits of trade to the Aksum Civilization were:
1. Significant developments of its maritime trading system that connected it to the Roman Empire, and India
2. There was also the invention of alphabets such as the Ge-z alphabetical system that was a collection of consonants. It was later on expanded to include vowels.
3. Due to her interactions with Rome, some of Rome's culture and construction of edifices such as the Rome Stele (known in Aksum as Aksum Obelisk) was put up.
4. Finally, there was the creation of its own coin. The Aksum civilization was the first African entity to create its own currency.
The negative effects
Because the kingdoms trade was largely agrarian-based, it suffered an irreversible historical decline, eventually stopped producing currency, and moved southwards away from the harsh weather.
