“Sustainable development is developmentthat meets the needs and aspirations of thecurrent generation without compromisingthe ability to meet those of futuregenerations”
Sustainable development
Brundtland Commission (World Commission onEnvironment and Development - WCED)“Our common future” (1987)
Brundtland Commission 1987

?
“Some people suggest that we are now on thebrink of the third great revolution of humanrace: that following the Agricultural Revolutionand the Industrial Revolution there will now bethe Sustainability Revolution”
Mather and Chapman (1995)
II Do we take care of the Earth?
Planetary ecological clock
Every second the area of 5 footballfields of rainforest disappears.
Planetary ecological clock
Every day 25 000 people die becauseof lack of water or its poisoning.
Planetary ecological clock
Every day 550 thousand animals diein torture in scientific laboratories,
200 millions every year.
Planetary ecological clock
Every day more arable soil disappearsthen is created during 1000 days.
Planetary ecological clock
Every hour 60 new people suffer fromcancer in U.S.A.
The ozone hole is a cause.
Planetary ecological clock
Every day 250 thousands of sulphur acidfall down as acid rain. It kills the life in
thousands of lakes and devastated millionhectares of forests.

IIIHow is the degradation of theEarth in scientists’ opinion?
Millennium Ecosystem Assessment (MA)
Millennium Ecosystem Assessment (MA)
Called for by UN Secretary General in 2000
Largest assessment ever undertaken
of the health of ecosystems
Prepared by 1360 experts from 95 countries
ECOSYSTEMS SERVICES
Approximately 60% (15 out of 24) of the
ecosystem services are being degraded orused unsustainably
Millennium Ecosystem Assessment (MA)
ECOLOGICAL FOOTPRINT
Mathis Wackernagel* & William Rees
„Our Ecological Footprint. Reducing HumanImpact on the Earth” (1996)
EF is a measure of how much biologically
productive land and water area an individual, acity, a country, a region, or humanity uses toproduce the resources it consumes and toabsorb the waste it generates.
ECOLOGICAL FOOTPRINT
„Ecological footprint”
Biocapacity = 1.8 ha/person
Average ecological footprint =
2.2 ha/person
EUROPE 2005. The Ecological FootprintReport of European Union
GLOBAL FOOTPRINT NETWORK; WWF
2003 – humanity’s Ecological Footprint exceeded
the Earth’s biocapacity by over 20%
ECOLOGICAL FOOTPRINT
REDEFINING PROGRESS
[Californian Institute works with a broad array ofpartners to shift the economy and public policy
towards sustainabiliyty
ECOLOGICAL FOOTPRINT OF NATIONS
2005 UPDATE (March 2006)
World's Ecological Footprint Exceeds Biocapacity by
Nearly 40%
50 000 – 150 000 species / year
140 – 416 species / day
Loss of Species Diversity
6 - 17 species / hour
Paul R. i Anne H. Ehrlich (1981)

IV What are basic laws in nature?
BASIC ECOLOGICAL LAWS
(American biologist)
Barry Commoner
„The Closing Circle” (1971)
Laws of Ecology
Barry Commoner (1971)
1. Everything is Connected to Everything Else
“...there are no separate individualbeings. All creatures are, to someextent, connected with others anddepend on them”Lewis Thomas [Dowd 1991]
Laws of Ecology
Barry Commoner (1971)
1. Everything is Connected to Everything Else
2. Everything Must Go Somewhere
3. Nature Knows Best
4. There is No Such Thing as a Free Lunch
This is us, Earth. We realize it sooner or later,
but there is no getting around it. If we do notlearn to live in harmony with the food chains,with the ecosystems, then gradually they willcome out of balance, and then they will die. Itis all a cycle and we are in it; we cannot
escape.
Robert Baden-Powell [Dowd 1991]
