FROM FOOTPRINT TO FINGERPRINT - KIDS FOR A GREEN TOMORROW 

(Od odtlačku nohy po odtlačok prsta - deti pre zelený zajtrajšok)

Task proposal for topic 1 General topic about environmental issues/climate changes. Calculate your own carbon dioxide emissions at http://energyworksus.com/carbon-calculator.html  ENERGY WORKS – electronic calculator for calculation of own CO2 emissions Present in a diagramme the differences in emissions between the pupils at each school for each of the following.Car use: kilometers/year + tons CO2 per yearElictricity usage: KW/year + tons CO2 per yearGas usage: tons CO2 per yearOil heating: tons CO2 per yearAir travel: kilometers/year + tons CO2 per yearTrain travel: kilometers/year + tons CO2 per year Present average results (for task 2) for each school/country. Here we should include results for ”general food and waste” and ”meat consumption”. Present the average number of trees each pupil ”consumes” per year.

SETTING THE TASK „CARBON FOOTPRINT“

What is carbon footprint ?

• carbon footprint is volume of gases

• it influences the Earth´s climate

• it is caused by a man

• it is mostly carbon dioxide

• the are also: carbon, methane and nitrous oxid

HOW TO REDUCE CARBON FOOTPRINT?

We can reduce carbon footprint:• minimum car driving,• don´t buy drinks in plastic bottles,• buy saving light bulbs,• ride a bike,• recycle,• washing at lower temperature,• don´t buy one off packings,• don´t eat a lot of meal ,• prefer having shower to having a bath...

A WALLBOARD IN ONE OF CLASSES WITH A MESSAGE

We have learn to fly in the sky like birds, to dive under the water like fish. There is the only left. To learn to

live on the Earth like people.
