10. 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?
11. M: 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!
