Environmental Health
  • Health of the complete environment is
    important.As it comprises of the human
    beings,plants, animals and the most important is

  • Environmental Pollution as we know today, is what
    that existed for centuries, but became prominent
    and significant only following the industrial
    revolution in 19th century.It is it that brought
    introduction of oil and its usage through various
  • Environmental Pollution occurs when nature does
    not know how to decompose some substances and
    they remain in our environment.
  • Such pollution is called Environmental Pollution.
  • Environmental Pollution occurs both in the
    developed and the developing nations across the
  • Based on its types The Environmental Pollution
    is classified as
  • Air Pollution
  • Water Pollution
  • Land Pollution
  • There can be several effects of the dying
    environment on humans, animals and the plants.
  • Cholorofluoro Carbons (CFCs) released from using
    ACs, refrigrators, deodrants also cause
    environmental pollution as they deplete the ozone
  • The ozone layer protects us from the harmful
    radiations from the sun that are ultraviolet
    radiations , thus preventing environmental
  • So it can be seen here that environmental
    pollution is a global issue and that needs to be
    tackled wisely.
  • Proper awareness and education is lacking in
    several regions especially in the developing
    nations where the problems are rising day by day.
    But the developed nations are also not far behind
    as their eminssions are greater and their share
    is more as far as the harm to the environment is
