Item 7: Area and yield

In front of you is a folding rule. You can choose to use it, or not, in this task. This is about how much space we need to grow our food. You have to think logically and do some math, and you are perfectly welcome to use the calculator on your mobile phone.

Here you will find the tasks and answer sheet. Good luck!

Did you know that: With the world's population today, there is approximately 2000 m 2 (2 acres) of arable land for each of us. This must cover the food, cooking oil, animal feed, drinks and fiber crops for the clothes and other textiles we need. How much area do you think you occupy?

What now?
