10. Discussion
All organisms on Earth use resources from the planet. (There are approximately 30 million species on the Earth)
What natural resources do we require for our needs?
Are these resources equally distributed around the World?

According to you, what do you think is meant by an ecological footprint?

12. Ecological Footprint (EF)
