What was the main environmental issue that occurred as a result of the Persian gulf?

The main environmental issue resulting from the Persian Gulf conflicts, particularly during the Gulf War in 1991, was the massive oil spill that released approximately 6 million barrels of crude oil into the Gulf. This spill caused severe damage to marine ecosystems, affecting wildlife, fisheries, and coastal habitats. Additionally, the deliberate setting of oil wells on fire released toxic smoke and pollutants into the atmosphere, further exacerbating air quality issues and contributing to climate change. The long-term ecological impact remains a concern for the region's environment and biodiversity.
