That’s bad for the environment.N:	So it’s better to have a smaller footprint, right?M:	Right, Nam. Non-renewable energy sources like coal, natural gas, and oil produce a lot ofcarbon dioxide. Those sources are going to runout 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.
