2. – Water is a renewable resource, but we are
depleting water in aquifers (porous, water
holding rocks) at a fast rate.
WATER SHORTAGES
3. Affected by climate
cycles and also
affected by human
interfernece, the Aral Click to add text
Sea is dying. In around Click to add text
25 years it has lost 75%
of its beginning
surface.
DYING ARAL SEA
4. – Growing population
– Large population concentrations near small
supplies
– Agricultural and industrial use
WHAT CAUSES THESE SHORTAGES?
6. > Many places that were warmer are now getting colder, and
many colder regions are getting much more colder or even
warmer.
> This describes the total of all weather occurring over a period of
years in a given place. It is the average weather condition of that
place. Climate tells us what it’s usually like in the place where you
live.
THE CLIMATE CHANGES
7. By polution from areoplanes flying, ships passing by to go through
or to visit the Antarctic and by sinking ships with 1000's of liters of
diesel, drinks, oil, gas and many more.
THE ANTARCTIC BEING SPOILED BY
HUMAN INTERFERENCE
8. When humans destroy wild land to build homes, factories, shopping malls, amusement
parks, garbage dumps, even to build a visitor center, store and restaurant in a park, the land is
changed. The animals that once lived there, from the bugs that lived in the ground to the birds
that ate them, all may disappear. Some can move to new home areas, but there are already
other animals living there. There is not enough food, water or shelter for all of them. Many of the
animals will die.When farmers spray chemicals on their crops to save them from pests (bugs and
molds and things that eat the plants), the chemicals get into the water and into the soil. Bugs that
do not hurt the crops die. The birds and mammals who eat these poisoned bugs may also die, or
they cannot reproduce, or their offspring die young.
Factories, automobiles, trucks and planes put chemicals into the air. The exhaust from their
engines contains tiny specks of toxic chemicals that fall on plants, on the ground, and into the
water. There, they get into the animals when the animals eat the plants, drink the water, or nest in
the ground. These animals, too, can die or not reproduce.
