The footprint. Activity 1

If you are at school try to discuss with your classmate if you have ever been in a situation where you have realized that your actions have been more pro-environment than against it. If you are at home do the same with a member of your family. Try to give 2 or 3 examples.

But, the big question is: do you know how big your carbon footprint is?. Here we propose you an easy activity to find it out. Working in groups, you’ll need to enter in this website and follow the instructions http://independent.footprint.wwf.org.uk/ . This website is an initiative of the

non-governmental organization (NGO) WWF. If you visit its website

(http://www.panda.org/) you’ll see that its main aim is to stop the degradation of the planet’s natural environment and to build a future in which humans live in harmony with nature, by: 

Conserving the world’s biological diversity



Ensuring that the use of renewable natural resources is sustainable



Promoting the reduction of pollution and wasteful consumption.

Before doing this activity, read activity 2, because you’ll need to write down data from the website in order to do activity 2.

15.

The footprint. Activity 2 a) Which fields is the test focused on?

b) Why does the amount of fish and meat you eat have an important impact on your carbon footprint?

c) Can you reduce your food footprint by buying more organic and local food?

d) What is the best way to reduce emissions from your car?

12

e) Travelling from London to Edinburgh the amount of CO2 released by a plane user, by a car user, by a train user, and by a coach user is:

f) How much can you reduce the amount of your heating energy by turning down one degree your thermostat?

g) What’s the percentage of energy reduction for lighting when using energy efficient bulbs?

h) Why is it so important to compost our kitchen and garden waste?

i)

How many hours would we be able to run an energy efficient bulb by recycling just one aluminum can?

j)

And finally, write down the results of your test:

o How many planets is your footprint?

o What is the percentage of your footprint in each field (food, travel, home, stuff)?

o How many tones of CO2 do you produce per year?

Working in groups research about these topics: 

Kyoto Protocol



Global warming and climate change



Kinds of clean energies

In each topic you must use at least a book, a magazine, a website and the presentations displayed on the library walls.

17.

Footprint. Activity 4

According to the topic you have researched, do a Power Point presentation where you explain your conclusions and the relationship between your research and the answers in activity 2 .

18.
