Let´s play the game about HUNTERS AND GATHERERS!
Each country will be one troup of prehistoric people-hunters/gatherers
These people who hunted mammoths and bisons and they eat them. Mobiles have really serious "mammoths´ impact on today´s environment. We will hunt and gather the old mobiles instead mammoths and bisons.
Can your troup hunt a whole bison or mammoth? If can, how many?
(If your troup is on distant education try to find out how many mobiles your school gathered last time, Your teacher can help you)
Key information:
1 
= 100 g (average weight)
= we need 100 kg of raw materials for its production (oil, copper, nickel, tin, gas, coal...)
=
| 1 x | = 100 kg  of raw materials needed for 1 production | |
| 8x 800 g (weight of 8 mobiles) | = 800 kg | = 1bison |
| 70 x 7 kg (weight of 70 mobiles) | = 7000 kg | = 1 mammoth 
|
Can you catch a bison or mammoth or more of them?
