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.
