SUSTAINABLE DEVELOPMENT

            Resources that the nature has provided  are  utilised by
            human beings  for the purpose of survival and welfare.
            There are two types of natural resources:
            1. Renewable Natural Resources (Water, Soil, Wind, etc.)
            2. Non-Renewable Natural Resources (Coal, Petrol, etc.)

            The  existence of mankind is linked to  the  conservation
            of the natural  environment and the natural  resources.
            Conservation means wise use of natural  resources to
            save them and prevent their exploitation, destruction or
            extinction. Natural resources are the most precious assets of mankind and there is a need to conserve them
            for the future generations, hence Sustainable Development is needed.  Sustainable development is  the
            development that meets the need of the present world without finishing off or depletion of natural resources
            and saving and protecting the potential of resources for future generation to meet the futuristic needs. It
            guarantees to strike a balance between economic growth, safety of environment and social well-being.

            Some examples that go with Sustainable Development are:
              Wind Energy: Wind energy is the energy harnessed from the motion of wind using turbine or windmill.
              Wind turbines convert kinetic energy in the wind into mechanical power and reduce the use of coal and
              other fossil fuel to produce power.



















              Solar Energy: Solar energy is harnessed from the sun using solar panels. It is non-polluting, inexpensive
              and renewable power source. It has minimised the use of water and coal for generating electricity.
