introduction to environment
The document discusses the environment and how human activities negatively impact it through pollution and improper waste management. It defines the environment as all living and non-living things that occur naturally, and notes that everything is interconnected. Human activities like urbanization, deforestation, agriculture, mining and industrialization contribute to air, water, soil, noise and radiation pollution. Improper disposal of solid waste is also a major problem, with Kathmandu generating over 450 tons per day. The document recommends adopting the "3R principle" of reduce, reuse and recycle to better manage waste, as well as composting organic matter and raising public awareness.
