Pencemaran Tanah ( Perubahan Lingkungan )

Summary

In this video, Widyaningsih discusses soil pollution, explaining how pollutants such as chemicals, dust, heat, sound, radiation, and microorganisms affect soil quality. The video highlights that certain materials like plastic can take up to 240 years to decompose, while aluminum cans take 500 years. Widyaningsih categorizes the sources of soil pollution into three groups: domestic waste, industrial waste, and agricultural waste. Examples include organic waste, industrial sludge, and pesticides like DDT used in agriculture. The video ends with a brief mention of upcoming topics on waste types.
