The United States has a population of approximately 330 million people. According to the World Bank, the United States' ecological footprint is 8.1 global hectares per person. Therefore, the total ecological footprint of the United States is 2.67 billion global hectares.
Therefore, the United States uses approximately 20 times more resources than Ethiopia. This means that it would take approximately 20 Ethiopians to use the same amount of resources that 1 American uses.
