Our footprint is the impact each of us makes on the planet by our everyday actions.
Every time we eat, switch on a light, get in a car, drink a beer, go on holiday or buy something to wear or use, we are adding to our footprint.
Our footprint on the Earth is calculated by how much land, sea and freshwater is needed to provide the food and materials we use in our everyday lives.
It also measures the amount of energy we use and the emissions we create from oil, coal and gas, as well as the amount of land we need to absorb all the waste we create.
It is not wrong to have a footprint.
What may be wrong is how big that footprint is.
