The carbon footprint shows how much carbon dioxide a person emits(排放) in everyday life. It measures the amount of fossil(化石) fuels and electricity someone uses as well as the number of products he or she buys. When we use our cars or heat our homes with carbon dioxide, various other gases are set free. 1
You can measure your carbon footprint by using a calculator that you can find on various websites. 2 In America, for example, every citizen produces about 28 tons of carbon dioxide and other dangerous gases a year while in Great Britain the amount is about 10 tons.
3 The way we travel, for example, has a major effect on our environment. Use your bike or walk for short distances. Public transport is a way of getting to places without putting a burden on the environment. 4 Many environmental experts, however, argue that it often saves energy to buy food that is produced naturally in faraway places in comparison with consuming food grown locally in greenhouses. In your home you can contribute to saving energy by turning off lights if you don’t need them or by avoiding the use of air conditioners. Recycling plastic glass and paper can also reduce your carbon footprint dramatically.
