PROBLEM SITUATION
The passing of time has given to
humankind the capacity to understand
and modify its environment in order to
improve the standard of living among
the different organized societies.
However, the same passing of time is
carrying
itself
other
important
challenges and inquiries whose
motivations converge to a single
common basis: the survival of human
race.
This
survival
is
being
jeopardized
by
the
following
hazardous situations (that might
happen now and in the coming
future):
PROBLEM SITUATION
METEOR IMPACT
GLOBAL WARMING
•Increase in global
temperature brings an
intensification in the
frequency of extreme
weather conditions that
can deteriorate the
livable conditions in the
planet.
• The last mass extinction led to the
demise of the dinosaurs and has been
found to have coincided with a large
asteroid impact; this is the CretaceousTertiary (K-T) extinction event.
OZONE DEPLETION
NUCLEAR WARS
LACK OF NATURAL
RESOURCES
•The possibility of a
nuclear war has been
brought to the table after
the creation of the atomic
bomb during World War
II.
http://www.motherplanet.net/g_Earth_Globe.html
• Natural resources in the Earth,
such as water, oxygen, fossil
fuels etc., are not unlimited and
its current consumption rate is
greater than the rate at which
they are being replenished.
•The main concern about the
ozone depletion is the is the
bad effects that the UV light
have on human health, such
as skin cancer, and planet’s
life, such as the extinction of
some species that are very
sensitive to this type of light.
PROBLEM SITUATION
Because of the latter reasons the idea of
creating a suitable environment for humans
that resembles the life in the Earth is
becoming a strong necessity in order to
guarantee the survival of human race an
avoid its extinction.
