Spaceship Earthis a world view term usually expressing concern
over the use of limited resources available on Earth and the
behavior of everyone on it to act as a harmonious crew working
toward the greater good.
It may have been derived from a passage in Henry George's best
known work,Progress and Poverty (1879). From book IV, chapter 2:It
is a well-provisioned ship, this on which we sail through space. If
the bread and beef above decks seem to grow scarce, we but open a
hatch and there is a new supply, of which before we never dreamed.
And very great command over the services of others comes to those
who as the hatches are opened are permitted to say, "This is
mine!"
WHY IT IS A SPACESHIP?Because it travels in the space at 29,6
km/sec and it is characterised by a special cabin, called
TROPOSPHERE, rich in oxygen, that provides us life.
WHAT IS THE EARTHS PROTECTIVE COVERING?It is a protective
stratus covering the troposphere with the function of defending
human beings from ultraviolet solar rays. Such covering is called
OZONE.
WHAT HAPPENS IF WE DONT RESPECT THE INTEGRITY OF OUR OZONE
COVERING? Unfortunately, for years we have used and still are using
gases that punch this protective covering, so that the suns
ultraviolet rays can penetrate the spaceship, with serious damage
for our health as well as for the integrity of all living species.
once the size and importance of our pressured cabin is understood,
lets consider now they way we accumulate CARBON DIOXIDE in it.
HOW CAN AN INDIVIDUAL PRODUCE SUCH AMOUNT OF CO2?To make 1 Kg of
bread corresponds to produce 0,4 kg of CO2To keep a bulp alight for
4 hours equals to produce 0,2 kg of CO2.
To take a shower means to emette 1 kg of CO2 in the atmosphere,
that is the same impact of using the dishwasherTo keep a
refrigerator working generates 40 gr of CO2 per hour.
Each kg of petrol burned is transformed into 2,6 kg of CO2, as
the carbon inside the petrol combines with 2 molecule of oxygen
which are in the atmosphere and have its same weight. To warm a
60-squared-metre flat in winter, contributes to an emission of 20
kg of CO2 per day.
One of the major damages is the GREENHOUSE EFFECT, of whom C02
is responsible for the 50%.
WHAT IS THE GREENHOUSE EFFECT? The trapping of the sun's warmth
in a planet's lower atmosphere, due to the greater transparency of
the atmosphere to visible radiation from the sun than to infrared
radiation emitted from the planet's surface.
HOW CAN THE INDIVIDUAL CITIZEN ACT The individual citizen can
follow 3 different ways:To reduce consumptions;to adopt a buying
behaviour oriented to eco-friendly products and processes;To
promote reforestation locally and internationally.
IN ORDER TO KEEP THIS BALACE, DOES EACH PERSON NEED TO REPLANT
0.78 HECTARES OF WOOD PER YEAR?
