IWhat does sustainability mean?

“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

Gro Harlem Brundtland, Prime Minister in Norway (1981,1986-1989, i 1990-1996)

“basic needs” “wants” or “desires”

?

“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

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]
