Argentina has become the first country to ban salmon farming due to concerns over its impact on the environment, health, and economy. The decision was met with resistance from local communities and environmental organizations, leading to a temporary halt in the project. The bill, which was unanimously approved, highlights the potential negative effects of salmon farming such as mass deaths of salmon, toxic algae blooms, and the introduction of exotic species. The ban aims to prioritize local communities and sustainable development while preserving biodiversity and the health of marine ecosystems.
