Translated:
Mai: Nam, yesterday I read that we all have a new carbon footprint.
Nam: Well, we all have footprints – we make it with our feet!
Mai: Haha, I know. But this kind of footprint is about the bad effect we have on the environment.
Nam: Yes, it’s been reported for days.
Mai: So our footprints get bigger when we use the energy that makes CO2. That’s bad for the environment.
Nam: Then it’s better to have a smaller carbon footprint, right?
Mai: That’s right, Nam. Non-renewable energy such as coal, natural gas, and oil produce a lot of CO2. These resources will soon be exhausted.
Nam: So they are different from wind, water, solar energy right?
Mai: Yes, all of them are also sources of energy. But they are recyclable. That means we can’t run out of them – they’ll last forever.
Nam: You have a big carbon footprint, don’t you, Mai?
Mai: Mine is small. I recycle the products that I use and I go everywhere by bike. My house has solar panels on the roof to receive solar energy.
Nam: Oh no! I think my footprints are big, and not just because of these oversized shoes!
a. Read the conversation again and answer the questions. (Read the conversation and answer the following questions.)
1. What is a carbon footprint? (What is a carbon footprint?)
2. What does ‘non-renewable energy’ mean? (What is “non-renewable” energy?)
3. Why is sunlight a renewable source?
(Why is sunlight a renewable energy source?)
4. Why does Mai think she has a small carbon footprint?
(Why does Mai think she has a small carbon footprint?)
5. What things do you think might create a big carbon footprint?
(What do you think makes up a large carbon footprint?)
Guide to answer
=>It’s about the negative effect we have on the environment.
(The carbon footprint is about the negative effect we have on the environment.)
2. “Non-renewable” means that it will run out if we use it.
(“Non-renewable” means something will run out if we use it.)
3. Sunlight is a renewable energy because we can’t use it all up, it will last forever.
(Sunlight is a renewable energy because we can’t use it all, it lasts forever.)
4. Mai thinks she has a small carbon footprint because she recycles the products she uses and she goes everywhere by bike.
(Mai thinks she has a small carbon footprint because she recycles the products she uses and she goes everywhere by bike.)
5. The products we use that are bad for the environment or the energy we use that produces carbon dioxide might create a big carbon footprint.
(The products we use that aren’t good for the environment or the energy we use produce CO2 can create a large carbon footprint.)
