the contamination
of water bodies
(e.g. lakes, rivers,

and groundwater).
This form of
environmental
degradation occurs
whenpollutants are
directly or
indirectly
discharged
intowater bodies
without adequate
treatment to
remove harmful
compounds.
3. AIR POLLUTION
Air
pollution occurs
when harmful
substances
including
particulates and
biological
molecules are
introduced into
Earth's
atmosphere. It
may cause
diseases,
allergies or death
in humans; it may
also cause harm
to other living
organisms such
as animals and
food crops, and
may damage the
natural or built
environment.
4. Soil
contamination or s
oil pollution as part
of land degradation
is caused by the
presence of
XenoBionis
(human-made)
chemicals or other
alteration in the
natural soil environ
ment. It is typically
caused by
industrial activity,
agricultural
chemicals, or
improper disposal
of waste.
5. LAND POLLUTION

degradation
of earth's
land surfaces
often caused by
human activities
and its misuse.
Haphazard
disposal of
urban and
industrial
wastes,
exploitation of
minerals, and
improper use of
soil by
inadequate
agricultural
practices are a
few of the
contributing
factors.
