In the first battle of what became known as the Emu War, in November 1932, the Australian army attempted to eliminate the plague of this bird, almost as large as an ostrich, with machine guns. It was damaging the country's cereal crops. But these birds dispersed very quickly and the operation failed. A few days later, according to chronicles, in a second campaign the soldiers adopted more mobile tactics and managed to shoot down hundreds of emus, but without sufficiently reducing the population. In fact, the Emu War is remembered as a symbolic victory of the emblematic emu over the Australian army.

One of the main arguments against the European Commission's plan to "create the world's largest free market" with Mercosur is the claim by many agricultural and environmental organizations that food grown with pesticides banned within the EU will enter Europe. But behind this unfair competition lies a key question: who produces these banned toxins that are then used in South America? The answer is paradoxical: a very significant portion is manufactured in Europe itself..
