Ecological footprint

Tallinn 2011

What is this?Measure of human demand on the Earth's

ecosystem

We can estimate:- how much of the Earth

- or how many planet Earths

it would take to support humanity if everybody

lived a given lifestyle.

The world-average ecological footprint in 2007 was 2.7 global hectares per person.

This is far too much!!

An inquiry about ecological footprint was

conducted in our school

74 students took part in that treatise

To conclude….Our school’s average ecological footprint is 2,31

It is still high, but lower than World’s average

How to reduce your ecological footprint

Electricity

Monitoring of water use

Waching and discussing films about consumption, garbage sorting and global

warming

ESTONIA

We can save electricity

Estonian electricityEstonia produces electricity from oil shale

1 ton of oil shale gives 850 kWh of electricity

The production of oil shale electricity leaves ash hills and pollutes air

Estonia also has green electricity produced by wind and water

Observation weeks FIRST WEEK: we did our usual things…watched TVand listened to

the radioused the computer as much

as we likedleft all appliances to stand-by

modeleft on the lights in the

kitchen, etc.

SECOND WEEK:we started saving

electricity…we were more outside we didn’t watch so much

TVused less computersdisconnected appliances

Results

FIRST WEEK

the families total

usage of electricity -

647 kWh

SECOND WEEK

the families total

usage of electricity –

460 kWh

We saved 187kW

Electricity saving in school2 ordinary weeks and 2 saving weeksWithin the ordinary weeks we spent

4705 kWh & 3607 kWhWithin the saving weeks we spent

3769 kWh & 3500 kWh

We saved about 1000 kWh of electricity

In school and at home we turned the lights off

You too can save electricity!

If someone isn’t in the room then turn off the

lights

If your family has two TV-s, then watch one TV

Do not leave your appliances in the stand-by

mode, unplug them

Spend more time outside!

Save electricity and don’t play with it!!!

We can save water

Monitoring of water usage in homesThe principle of this study was :

a)to get to know people's domestic water consumption

b)To make them consume less

We had two observation weeks

The usual week and saving week USUAL WEEK

We used water as usual

The main water-consuming appliances:

- washing machine

- coffee pot

- kettle

SAVING WEEKWe tried to save as much

as possibleSuggestions:

1) If you wash your teeth don’t keep the water running!

2) Do not wash the dishes under running water!

ResultsTHE USUAL WEEK

The average of consuming:

warm water-64,684 m³

cold water -61,425 m³.

THE SAVING WEEK

The average of consuming:

warm water-63,924 m³

cold water -61,127 m³Hot water - 0,76m³

Cold water - 0,298m³SAVINGS

Watching and discussing films

Estonian Green Party leader´s lecture

Green Party leader Marek Strandberg gave a lecture about consumption and showed a movie

If we continue the similar type of behaviour:

- The U.S. would need 5 Earths

- Estonia would need 3 Earths

- China would need 1.4 Earths

Watching moviesAlmost every grade watched some ecological movie

5th grade - about sorting trash - ,,Help recycling’’

9th grade - about greener economy options - ,,Good new world’’

7th-8th grade - about ecosystems and the plants in it - ,,Intelligent plants’’

11th grade - about global ecology problems - ,,Home’’

Activities after movies:

11th grade - open discussion about subject

7th and 8th grade - discussed film with Green Party leader and answered questions about film

5th and 9th grade – had a workshop-competition

- Make Your Own Ecological Board Game -

5th grade in workshop

9th grade in workshop

Board Games Competition5th and 9th grade students competed in

inventing ecological board games

The best-looking game - from 5th gradeThe best ideas in game - from 9th grade

Winners were from 5th grade

Some good ideas and advices: Enjoy Your day, but use garbage bin!

Do not leave Your used gum everywere!

Hug a tree!

Buy nothing today!

The garbage-sorting is really fun!

You can change world – you can start it now and from yourself!
