Abstrakt
Produkcja biopaliw oznacza zużywanie zasobów żywności – to prowadzi do narastania problemu głodu. Szacuje się, że więcej niż 66% ludzi na świecie cierpi z powodu niedożywienia. Głód jest także najważniejszą przyczyną śmierci. Tymczasem ok. 40% amerykańskiej kukurydzy przeznacza się na produkcję etanolu. Co więcej, na wytworzenie 1 litra etanolu zużywa się 1,6 litra ekwiwalentu ropy. W tej sytuacji Ameryka musi importować ropę w celu produkcji etanolu, ponosząc przy tym ogromne koszty, zmniejszając zarazem dostępność żywności dla obywateli.
