Human Impacts on the Hydrological Cycle
What is Hydrological
Cycle?It is a sequence of conditions
through which water passes or circulates on and below the
earth’s surface and the atmosphere. It is commonly known as the Water Cycle.
In simplier term. . .
Water Cycle is the nature’s way of
recycling water on Earth!
IMAGINE? Only 3% of the worlds water is safe for human consumption.
Let’s take a look at this. . .

Transpiration
EvaporationCondensation
Precipitation
evaporation of
water from
leaves of
plants and its
corresponding
uptake from
roots in the
soil.
Process in which
liquid changes to gas.
Process
by which
matter
changes
from gas
phase
into a
liquid
phase.
When cloud particles become too heavy to remain suspended in the air, they fall to the Earth.
Human Activities that impacts the water cycle:
Vast usage of chemicals, pesticides, fertilizers and other forms of
pollutions can cause Eutrophication.
What is Eutrophication?
Eutrophication is a process in which bodies of water (lakes, ponds,
and rivers) receive excess nutrients that stimulate excessive
growth of algae.

Algal Bloom results to this:
Another Human activity leads to this. .
Manila Bay for example has become
a huge floating dump in Metro
Manila.
Human activities like usage of chemicals,
pesticides and dumping wastes in the bodies of water can lead to total
Hydrological Cycle Destruction. .
THANK YOU! Let’s all be a catalyst of
change!
