Oil spill cleanup involves various methods to remove oil from affected areas, such as oceans, rivers, and shorelines. Common techniques include using booms to contain the spill, skimmers to collect the oil, and dispersants to break down the oil into smaller droplets. Additionally, absorbent materials like pads or mats can soak up the oil, while bioremediation uses microorganisms to naturally degrade the oil. Effective cleanup is crucial to minimize environmental damage and protect wildlife and ecosystems from the harmful effects of oil pollution.
