The invasive alien species (IAS) are animals introduced by men in certain territories where they’re not normally found. These animals cause serious problems for their new environment, by reproducing and slowly extinguishing native species along with fighting for food and space. IAS is the second cause of species extinction worldwide, but in Argentina it became the first one. Argentina’s ecosystem balance was lost through the invasion of animals such as sheep (originally from North America), beavers (originally from North America and Eurasia) and the bighorn pig (originally from Europe). “Fundación Banco de Bosques” an NGO that protects native ecoregions in Argentina wanted to expose this issue and raise awareness from an unexpected place. Therefore, we decided to create a polemic campaign, by showing hunters using an alien species rather than rifles but replacing rifles with an alien species. Introducing foreign species causes as much damage as illegal hunting Help preserve native ecosystems
