Look at the world’s footprint. What does global overshoot or ecological deficit mean?

 

 

 

 

 

 

What is the global overshoot in % or # of planets?

 

 

Currently, the earth has 13.4 billion globally productive hectares. The average person uses 2.1 gha for his/her needs and wants. Assuming all the world’s globally productive ha were used for humans, at the average rate, how many people could the earth support, long term?                   How does this compare to the world’s current population?

 

 

 

 

Why might we not want to use all the globally productive ha for human purposes?
