The significant environmental issue along the Pacific Coast is ocean pollution.

Ocean pollution poses a major environmental challenge along the Pacific Coast, threatening marine ecosystems, wildlife, and human health. The region faces numerous sources of pollution, including plastic waste, oil spills, and agricultural runoff, which contaminate the water and harm marine life. Plastics, in particular, are a pressing concern, as they break down into microplastics that can be ingested by fish and other animals, leading to health issues and entering the food chain. Additionally, harmful algal blooms fueled by nutrient pollution can produce toxins that affect both aquatic life and coastal communities. Efforts to combat ocean pollution involve community cleanups, advocacy for sustainable practices, and stricter regulations to protect the coastal environment. Raising awareness about the impact of pollution is essential for preserving the health and biodiversity of the Pacific Ocean and ensuring a clean environment for future generations.
