conservation of natural resources, deforestation, loss of biodiversity, environmental pollution,
deterioration of life support systems and issues like global warming, ozone depletion etc. All this and
much more is dealt within the subject.
The course covers all the major components of the environment including natural resources, ecological principles and population dynamics, pollution, wildlife conservation, and impact of industrialization.In addition, it also addresses environment related socio-economic, cultural and ethical aspects, which are important to ensure a sustainable future for humans.
