Ecological Global Footprints

What's a global footprint?

The Earth has a limited number of resources and we're using them up more quickly than they can be replaced - if they can be replaced at all.At school you use resources when you eat food and drink water. The school uses energy to make the lights and computers work and to keep the rooms warm. The clothes you wear and the building itself are made from nature's resources.We all use these resources in different amounts. The amount we use is called our Ecological Footprint - that is the impact that we have on planet Earth.

The Schools' Global Footprint has a Global Footprint Calculator to help you to work out the quantity of resources that you and your school use, compared with what is available in the world. You can see if this is sustainable for the future and you'll get suggestions on how to reduce your impact on the planet.
