C 
Listen and read: 
Mai : Nam, I read yesterday that we all have carbon footprint. 
Nam : Well, we all have footprints - we make them with our feet. 
Mai: Ha 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 produce a lot of carbon dioxide. Those sources are going to run out soon too. 
Nam : So, they are different to wind, hydro, and solar? 
Mai: 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. 
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 panels on our roof at home to catch the sun’s energy, too. 
Nam : Oh no! I think my footprint is big, and not just because of these big shoes!
