There are approximately 6 billion people in the world and there is 2.97 million square miles of land in the island continent of Australia. 2.97 million square miles breaks down to 1,900,800,000 acres which then converts down to 7,603,200,000 quarter acre blocks of land. So we could hypothetically give every person in the world a quarter acre block of land and they would all fit into an area the size of Australia. Each would have enough land that they could all have gardens and grow a substantial supply of their own food, and we would still have 1,603,200,000 quarter acre blocks, or an area roughly half the size of Queensland left over, plus the entire rest of the world. Now let’s pause to let that sink in to your brain for a second. All the people, that’s every man woman and child on earth, would comfortably fit inside Australia; each individual person could have a quarter acre block of land, and we would still have half of Queensland and the entire rest of the planet left totally unoccupied.
