Trang 11B LISTEN AND READ
M: Nam, I read yesterday that we all have a
carbon footprint.
N: Well, we all have footprints – we make them with our feet!
M: Ha ha, I know that But this kind of footprint is about the
negative effect we have on the environment.
N: Right, it’s in the news a lot these days.
M: So our footprint is bigger when we use energy that
produces carbon dioxide That’s bad for the environment N: So it’s better to have a smaller footprint, right?
Trang 12M: Right, Nam Non-renewable energy sources like coal,
natural gas, and oil produce a lot of carbon dioxide Those sources are going to run out soon too.
N: So, they’re different to wind, hydro, and solar?
M: Yes, they’re all sources of energy too, but they’re
renewable That means we can’t use them all up – they will last forever.
N: Do you have a big carbon footprint, Mai?
M: Mine’s small I recycle the products I use and I go
everywhere by bike We have solar panels on our roof at home to catch the sun’s energy, too.
N: Oh no! I think my footprint is big, and not just because of
these big shoes!
Trang 14a Answer the questions.
1 What is a carbon footprint?
2 What does 'non-renewable energy' mean?
3 Why is sunlight a renewable source?
4 Why does Mai think she has a small carbon
footprint?
5 What things do you think might create a big
carbon footprint?
Trang 151 What is a carbon footprint?
2 What does 'non-renewable energy' mean?
3 Why is sunlight a renewable source?
It’s about the negative effect we have on the environment.
‘Non-renewable energy’ means that it will run out if we use it.
Sunlight is a renewable source because
we can’t use it all up, it will last forever.
Trang 164 Why does Mai think she has a small carbon
Mai thinks she has a small carbon footprint because she recycles the products she uses and she goes everywhere by bike.
