2. WATER
A valuable resource…
• It is a renewable resource
and theoretically
inexhaustible, the basis of
all life forms. Naturally
present in large quantities,
either in liquid form (seas,
rivers and lakes cover about
73% of Earth's surface) and
strong (polar ice caps,
glaciers, snowfields in), and
the state of steam into the
atmosphere. Water is
essential to the human race
in all its many uses:
domestic, agricultural,
industrial.
3. WATER
The molecules of water
• Water is a liquid
whose molecule
consists of an
oxygen atom to
which they are
attached two
hydrogen atoms:
its chemical
formula is
therefore H2O.
4. WATER
• Water is an
essential component
of all living
organisms on our
planet. And
'therefore also
present in the
human body at
varying rates
depending on age,
sex and weight.
5. The cycle of water
• The water
naturally occurs in
liquid form, in the
sea and in the
rivers, or solid, in
the glaciers of the
mountains or the
poles or in the
form of vapor in
the atmosphere
6. THE WASTE
• The waste left
unchecked become
a source of
pollution,
environmental
degradation and
cause
proliferation of
dangerous animals
and insects
7. Ricycling glass
• The glass objects
before they are
inserted into the bell
must be separated by
paper, caps and
possibly rinsed.
The glass that you will
get with the recycling
will be dark if you do
not provide a
separate color.
8. RECYCLING PAPER
• Recycle paper mean:
lower costs for its
disposal,
lower costs for its
production,
ecological protection of
forest resources.
The bins are yellow.
The lid of the box is
always closed after use.
It is forbidden to settle
out of the container
every type of waste
9. Recycling plastic
• Plastic recycling is a
specific area of
waste recycling, and
consists of a set of
operations that are
carried out on
compounds from
waste plastic to get
new material to re-
enter in production
processes.
10. Recycling aluminum
• Recycling aluminum
is a specific area of
waste recycling, and
consists of a set of
operations that are
carried out on
compounds from
waste aluminum to
get new material to
re-enter in
production
processes
11. Pollution • Pollution is an alteration
of environment, natural
or man-made, and can
be just as man-made or
natural. It produces
temporary discomfort,
disease or permanent
damage to life in a given
area, and can put the
area out of balance with
the natural cycles exist.
L 'alteration can be of
varied origin, chemical
or physical
12. Air pollution
• Atmospheric
pollution indicates all
physical, chemical
and biological agents
that modify the
natural
characteristics of the
'atmosphere
13. Water pollution
• Water pollution is an
alteration of ecosystems
that have water as a
fundamental
component.
It is caused by several
different factors, such as
discharges of industrial
and agricultural activities
and normal human
activities that come into
rivers, lakes and seas
14. Soil pollution
• Soil pollution is a
phenomenon of altering
the natural chemical
composition of the soil
caused by human
activity.
This type of pollution
leads to the alteration
of chemical, physical and
biological soil
predisposes to erosion
and landslides and may
result in entry of
harmful substances in
the food chain to humans
15. Noise pollution
• Noise pollution is
caused by
excessive
exposure to
sounds and noises
of high intensity.
This can happen in
cities and in
natural
environments
16. Damages of pollution
• Noise pollution can cause
psychological problems over
time, pressure and stress to
people who are constantly
placed under Air pollution has
extremely negative impact on
the environment and global
warming, but there are also
many consequences health of
the human body.
The effects sorties are divided
into acute and chronic: acute
type are asthma and bronchial
circulation disorders, chronic
gender are all disorders related
to exposure over the long term:
cough, phlegm, decreased lung
capacity, chronic bronchitis .
17. Correct behaviour• The packaging is excessive today.
Avoid unnecessary package. Do
not buy food in plastic containers
in shops and supermarkets,
because they do not decompose in
landfills, and if you burn at a
temperature below a certain
threshold may produce toxic
substances such as dioxins and
furans. In general I unwrapped
the Tetrapak, polystyrene, plastic
and aluminum, which too often end
up in meadows, forests, rivers and
landfills. It is good to resort to
reduced packaging and with
recyclable material such as paper,
glass and new bioplastics
18. Correct behaviour
• Avoid as much as
possible to use
plates, cutlery, cups
and plastic bottles.
About half of the
volume of the
garbage consists of
plastic and coating
(package) which can
be reduced using
normal glasses,
plates and cutlery,
all reusable objects
simply by washing.
21. Correct behaviour
• The ecological
house is the one
that consumes the
least energy: not
too big, sober,
insulated, with the
bare minimum of
household
appliances and high
energy saving light
bulbs with high-
efficiency stove,
etc.
23. Ecological Footprint
• The ecological
footprint is an
indicator used to
assess the human
consumption of
natural resources
than the Earth's
capacity to
regenerate
24. Ecological Footprint
“As our feet
leave a footprint
on the
ground, so our
styles
of life leave
footprint on the
earth. "
Think about it!!
