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

House types

House and commodity expenses

Transport expenses

Food expenses

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 electricity Estonia 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 radio used the computer as much as we liked left all appliances to stand-by mode left on the lights in the kitchen, etc. SECOND WEEK: we started saving electricity… we were more outside we didn’t watch so much TV used less computers disconnected appliances

Results FIRST WEEK the families total usage of electricity kWh SECOND WEEK the families total usage of electricity – 460 kWh We saved 187kW

Electricity saving in school 2 ordinary weeks and 2 saving weeks Within the ordinary weeks we spent 4705 kWh & 3607 kWh Within 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 homes The 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 WEEK We tried to save as much as possible Suggestions: 1) If you wash your teeth don’t keep the water running! 2) Do not wash the dishes under running water!

Results THE 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 m³ Hot water - 0,76m³ Cold water - 0,298m³ SAVINGS 

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 movies Almost 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 Competition 5th and 9th grade students competed in inventing ecological board games The best-looking game - from 5th grade The 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!
