(6)(7)Listen and repeat
Mai :Nam , I read yesterday that we all have a carbon footprint
Nam : Well , we all have footprints – we make them with our feet !
Mai :Ha , I know that But this kind of footprint is about the negative effect we have on the environment
Nam : Right , it’s in the news a lot these days
Mai : So our footprint is bigger when we use energy that produces carbon dioxide That ‘s bad for the environment
Nam : So it’s better to have a smaller footprint, right ?
Mai : Right , Nam Non – renewable energy sources like coal, natural gas, and oil producea lot of carbon dioxide Those sources are going to run out soon too
Nam : So , they’re different to wind , hidro, and solar ?
Mai : Yes , they’re all sources of energy too ,but they’re renewable .That means they can use them all up – They will last forever
Nam :Do you have a big carbon footprint , Mai ?
Mai : Mine’s small I recycle the products I use and I go everywhere by bike We have solar pannals on our roof at home to catch the sun’s energy , too
(8)1 What is a carbon footprint ? (Dấu chân carbon gì?)

5 What things you think might create a big carbon footprint ?
a Answer the following questions
It’s about the negative effects we have on the environment
‘Non –renewable energy’ means that it will run out if we use it
Sunlight is a renewable energy because we can’t use it all up , it will last forever
Mai thinks she has a small carbon footprint because she recycles the products she uses and she goes everywhere by bike
