Kingdom of Kush was located next to Egypt and Persia it is hot and dry where Kush is. Tt's also along the Nile river the Nile river is home to many dangerous species of animals like crocs and hippos. Many people have gotten attacked from the animals in the Nile. Kush is also located next to the Red sea the Red sea is one of the saltiest seas in the world it has so much wildlife like sharks, sea turtles and much more.
The weather is hot and dry sometimes, Kush and other civilizations around will get sand storms these can happen because there isn't any rain water. Kush would survive off of rain water and the Nile rivers fresh water supply. The problem that was not good for the iron industry in Kush is trees they would use trees to heat up the furnaces the dessert across the Red sea had plenty but when they almost used them all it was horrible for Kush.
