Environmental Pollution:

1. Air Pollution:
   • Caused by the combustion of coal, petrol, and diesel, industrial processes, solid waste disposal, and sewage disposal.
   • Pollutants include oxides of sulfur, nitrogen, carbon monoxide, hydrocarbons, ammonia, lead, aldehydes, asbestos, and helium.
   • Effects include respiratory diseases, urban smog, and acid rain.
   • Remedies include promoting afforestation, using electrical appliances with high energy ratings, using CNG for automobiles, and installing proper chimneys in industries.
2. Water Pollution:
   • Results from the addition of harmful materials in water, making it unfit for use.
   • Major sources include industrial waste, agricultural chemicals, and domestic sewage.
   • Impacts include waterborne diseases like diarrhea and intestinal worms.
   • Solutions involve treating industrial effluents, regulating the use of fertilizers, and improving sewage systems.
3. Land Pollution:
   • Caused by improper disposal of industrial waste, use of pesticides and fertilizers, and deforestation.
   • Leads to soil erosion, waterlogging, salinization, and loss of soil fertility.
   • Measures include banning shifting cultivation, regulating the use of chemicals, and promoting sustainable agricultural practices.
4. Noise Pollution:
   • Generated by traffic, industrial activities, construction work, and loudspeakers.
   • Causes hearing problems, headaches, anxiety, and other health issues.
   • Controlling noise pollution involves regulating the use of loudspeakers, improving urban planning, and creating noise barriers.

Urban Waste Disposal:

• Urban centers generate large quantities of solid waste, leading to environmental and health hazards.
• Problems include improper collection, disposal, and management of waste.
• Solutions involve treating waste as a resource for generating energy and compost, improving waste collection systems, and promoting recycling.

Slums:

• Slums are overcrowded areas with poor living conditions, lacking basic amenities like water, sanitation, and proper housing.
• Inhabitants often work in low-paid, high-risk jobs, leading to undernourishment and vulnerability to diseases.
• Addressing slum issues requires improving housing conditions, providing basic amenities, and creating employment opportunities.

Migration:

• Migration from rural to urban areas is driven by the search for better employment and living conditions.
• Positive impacts include availability of cheap labor and improved standards of living.
• Negative impacts include overpopulation in urban areas, inadequate infrastructure, and increased crime rates.
• Managing migration involves developing rural areas, improving urban infrastructure, and creating balanced regional development.
