b) Water resources : Use and over-utilization of surface and ground water, floods, drought, conflicts over water, dams-benefits and problems.
c)Mineral Resources : Use and exploitation, environmental effects of extracting and using minerals resources, case studies.
d)Food Resources: World food problems, changes caused by agriculture and overgrazing, effects of modern agriculture, fertilizer-pesticide problems, water logging, salinity, case studies.
e)Energy resources : Growing energy needs, renewable and non renewable energy sources, use of alternate energy sources, Case studies.
f)Land Resources: Land as a resource, Land degradation, man induced landslides, soil erosion and desertification.
Role of an individual in conservation of natural resources
Equitable use of resources for sustainable lifestyles.
