Le thesis kaDkt Steve Glassey ihlanganisa i-exegis yohlu lwezincwadi zakhe ezikhuthaza imiphakathi ekwazi ukumelana nezinhlekelele ehlanganisa izilwane kanye nemiqondo emisha ye-OneRescue, egxile kakhulu ezilwaneni ezingabangane namalungiselelo okulawulwa kwezimo eziphuthumayo.
Ngo-2005, iSiphepho uKatrina sagadla eningizimu-mpumalanga ye-United States hhayi nje kuphela ukulahlekelwa okuphawulekayo kokuphila komuntu, kodwa usizi lwamakhulu ezinkulungwane zezilwane ezasala ngemuva. Isifundo esibalulekile kule nhlekelele sasiwukuthi izidingo zezilwane ezifuywayo (izilwane ezihambisana nazo) zazigunyaza ukufakwa ezinhlelweni zokuphuma ezimweni eziphuthumayo, ukuze kuncishiswe ugqozi lwabantu abahluleka ukuphuma ngoba bengakwazi ukuthatha izilwane zabo ezifuywayo. Le thesis isiphetho socwaningo lokuthi lezo zifundo zisetshenziswe ngempumelelo futhi zafundwa yini, ngokugxila ngokukhethekile emthethweni wokuphathwa kwezimo eziphuthumayo waseNew Zealand kanye nenqubomgomo yomphakathi. Imibiko eminingi nama-athikili abuyekezwe ontanga afakiwe futhi ahlinzeka ngolwazi oluthile ukuze kuqhathaniswe ukusebenza kahle kwezinhlelo zenhlekelele ezibandakanya izilwane eNew Zealand nakwamanye amazwe.
