Pollution cleanup refers to the process of removing harmful substances from the environment, such as air, water, and soil. This can involve various methods, including physical removal, chemical treatment, and biological processes. The goal is to restore ecosystems and protect public health by reducing the impact of pollutants. Efforts in pollution cleanup often focus on contaminated sites, such as landfills, industrial areas, and water bodies. Organizations and governments may work together to implement cleanup projects, using technologies like bioremediation or chemical neutralization to effectively address pollution and promote a healthier environment.
