A different type of footprint
GETTING STARTED
Task 1. Listen and read.
Mai: Nam, I read yesterday that we all have a 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`re 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!

.
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
Mai thinks she has a small carbon footprint because she recycles the products she uses and she goes everywhere by bike
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
