In the early 1900s, Australia was in the grips of a cactus epidemic. The prickly pear cactus was covering an area the size of the Great Britain, or the state of Oregon. Farms were strangled and other plants crushed beneath the weight of a sea of thorny cladodes.
Until the Cactoblastis cactorum moth, another introduced species, miraculously destroyed most of the cactus in less than a decade.
This is a fascinating story of introduced speceies, poison guns, and before-and-after photos!
