The document discusses the interaction between the environment and human activities like industry. It defines the environment as the physical, biological and chemical factors surrounding organisms. The environment consists of several components including the biosphere, atmosphere, hydrosphere, lithosphere and anthroposphere. Industry impacts the environment through air, water and soil pollution from emissions and waste. Major pollutants from different industries are identified. The document concludes by outlining some solutions like choosing sustainable raw materials, minimizing pollution and designing for recycling to reduce industry's environmental impact.
