“Do 2030 roku globalne zapotrzebowanie na wodę przekroczy dostępne zasoby wody o 40%, jeśli nic nie zmienimy w naszym obecnym zarządzaniu wodą. (2030 Water Resources Group) Wyprodukowanie jednej koszulki może wymagać nawet tyle wody, ile wystarczyłoby jednej osobie do picia przez 2,5 roku. Obliczenia bazowałam na dostępnych szacunkach, według których 1kg bawełny pochłania ok 10000 litrów wody. (Water Footprint Network) *lumpowanie wiąże się z niewielkimi ukrytymi kosztami wodnymi (głównie transport), ale to jedynie ułamek wody zużywanej do produkcji nowych ubrań:) źródła: 2030 Water Resources Group; UNEP; Water Footprint Network; Ellen MacArthur Foundation”
Summary
Globalne zapotrzebowanie na wodę ma przewyższyć dostępne zasoby o około 40 % do 2030 r., jeśli nie zmienimy obecnego zarządzania wodą. Szacuje się, że 1 kg bawełny wymaga ok. 10 000 l wody, co oznacza, że produkcja jednej koszulki (ok. 0,2 kg bawełny) zużywa około 2 000 l – ilość zbliżoną do wody, jaką przeciętny człowiek wypije w ciągu około 2,5 roku.
