How did the nature and climate of the Arabian Peninsula affect the occupations and lifestyle of its population?

The nature on the territory of the Arabian Peninsula is rather poor, the desert takes up a lot of space, and the climate is dry, therefore, the occupations of the inhabitants were as follows:
Trade, maritime and caravans. The peninsula is surrounded by the Arabian Sea, the Persian Gulf and the Red Sea. It is convenient to trade with neighboring countries through them. Caravan trade is possible overland in the north of the peninsula, for example, one caravan to Jerusalem, the other to Baghdad. They bought it from neighbors. what we ourselves lacked, grain, for example.
Camel breeding. In dry desert climates, they are more comfortable than horses.
They fished in the sea and dug for pearls.
Pig breeding probably did not develop even before the advent of Islam. There are no suitable conditions.
Agriculture was developed in the oases. Crops that are tolerant to dry climates, such as dates, have been successfully grown.
