”Your jeans are
a poison bomb”
(Ekonominyheterna 2006)
Cotton production consumes more than
11% of all farming chemicals used on the
earth and 25% of all pesticides
One pair of jeans ”consumes”
6600 litres of water
13,2 m² land
0,5 kg chemicals
103 different pesticides
Is there a ”peak cotton” round the corner?
