What we're trying to do in this is show is show who God is and how he acts, and Who We Are and how we should act in relationship to him and his created design.
This is called biblical economics
The branch of knowledge and revelation concerned with the production, consumption, and transfer of resources is called economics.
Biblical Economics focuses on the behaviour and interactions of economic agents and how economies work.
On day five, God filled the seas with all manner of fish and sea monsters and the air with every kind of flying bird. He commanded them to be fruitful and multiply and fill the seas and the air.
It is because of His command to be fruitful and multiply that we are able to hunt and fish to this day. Again, we can see God's plan of economics being formed right from the beginning of creation.
