Final answer:
The United States has a higher per capita ecological footprint than China, and its total global ecological footprint is also larger due to its higher population.
Step-by-step explanation:
China has a larger population than the United States, so when comparing ecological footprints per capita, we need to consider this difference. The ecological footprint is a measure of the impact of human activities on the environment. The United States has a higher per capita ecological footprint than China, meaning that on average, each person in the United States has a larger impact on the environment compared to each person in China. However, in terms of total global ecological footprint, the United States has a larger footprint than China due to its higher population and higher per capita footprint.
