You leave footprints when you walk in the sand, the mud and when you’ve got wet feet. You also leave something called a carbon footprint when you use fossil fuels. Heating oil to keep your house warm or fuel for your family’s car, create carbon dioxide, also called CO2. Carbon dioxide is called a greenhouse gas. Many scientists believe that greenhouse gases are making the earth too warm. Your carbon footprint is the total amount of CO2 you create, so a big carbon footprint is bad for the planet.
Choosing to walk or bike just one mile to the shop and back once a week rather than drive will see fuel savings of £20.80 and 27kg in CO2 each year – that’s the equivalent of charging your smart phone 3,443 times.
