Our lands and waters have been severely damaged by the actions of colonisers. It started with clearing of trees to make way for farmland. Our drinking water supplies were fouled by farm animals. Our sacred sites were razored away with mining operations. This still happens today. Uranium mining has left country poisoned. Rivers and water sources have been over-exploited. Mismanagement of the land has led to catastrophic bushfires. Nuclear weapon testing in the 50s and 60s led to deaths and serious long-term health effects for Aboriginal people in test areas, and made their lands uninhabitable.
