So I then began looking at all the research plots I could over the whole of the Western United States where cattle had been removed to prove that it would stop desertification, but I found the opposite, as we see on this research station, where this grassland that was green in 1961, by 2002 had changed to that situation.
Så jeg begyndte at se på de forsknings-områder i det vestlige USA hvor kvæg var blevet fjernet, for at bevise,  at det ville standse ørkendannelsen. Men jeg fandt det modsatte, som vi ser på denne forsøgsstation, hvor området, som var grønt i 1961 så sådan ud i 2002.
