SUSTAINABLE DEVELOPMENT
Definition
Sustainable development is a
way for people to use
resources without running
them out. The term is defined
as development with
sustainability that "meets the
needs of the present without
compromising the ability of
future generations to meet
their own needs”.
Earth Summit in Rio de Janeiro
United Nations Conference on "Environment and
Development" commonly called the Earth Summit was held
from 3 - 14 June 1992 in Rio de Janeiro in Brazil. The
Conference was attended by representatives of 172 countries.
The conference was organized in the 20th anniversary of the
first United Nations conference on the problems of the
environment, held in Stockholm in 1972.
The results of Rio de Janerio Summit
Making documents including ideas to improve the
ecology in other countries for example: Agenda 21
– which has ways to keep sustainable development
in run till the end of XXI century some of them
are:
International cooperation with resources development;
Changing model of consumption;
Defending human life, ecosystems, and atmosphere.
Why is sustainable development so
important?
The effects of lack of the sustainable development can be dangerous for
our world.
If all natural resources are gone, we won’t have anything to make energy.
If we don’t help the third world countries, the environment will be
destroyed (rich companies produce goods in non-ecological way there)
How to use natural resources wisely?
Be sure that the production of this resources is greater than the
consumption.
Don’t create more problems by solving only one; burning coal
produces energy, but it also adds carbon dioxide to the
greenhouse gases.
We should use more types of energy
sources which are free, renewable and
sustainable, for example: solar, wind,
tidal and thermal energy. Instead of
using limited recources, like: coal, oil
and natural gases.
The renewable types of energy sources could power a lot of
industries and cities, only if more money would be involved.
People shouldn’t be using new things (for example: electronics)
faster than they are produced, because then a lot of these
products are being wasted.

Lighting at school and how much waste
it generates
Using 35W bulbs
(now)
Using 5W bulbs
Conclusion Now to reduce CO2 generated only by light in our school we need 40000 trees
it is 10 km2 of forest ( size of Warsaw is 519 km2)
If we changed our bulbs to eco ones the number would be reduced to 5500
trees it is 1,5 km2 of forest.
A few interesting facts about forests in Poland:
• In 2010 trees were planted on an area equal
to 7,5 thousands football pitches
• By the year 2020 30% of Poland will be
covered by forests according to a goal set in
1995
Students from our school took part in an all-Poland
competition for the best poster or movie to promote saving
energy.
Saving energy - competition
Our friend Kuba Kalemba from grade II, achieved
a distinction it this competition.
Distinction
Thank you for your
