There is enough space for everybody. What the world lacks is good education.
The important resource is people. When oil becomes economically irrelevant the Arabian peninsula will be economically irrelevant despite having had a 100 years of sitting on top of huge oil resources.
Ireland’s natural resources are some land that’s good for raising cattle and sheep and they grew rich off of pharmaceuticals, IT and other US multinationals. Luxembourg grew rich off of banking.
Natural resources are nowhere near as important as people. People turn dirt into valuable things. Without them it’s just dirt.
