Dấu chân carbon” là gì?(What is carbon footprint ? )
Tác động của bạn đến môi trường mạnh đến cỡ nào, những hành động thường nhật của bạn thải thêm vào khí quyển bao nhiêu khí carbonic (CO2); tất cả những số liệu đó sẽ được tính toán đo lường và hiển thị bằng một con số mà chúng ta gọi là carbon footprint – dấu chân carbon. Con số của bạn càng lớn thì tác động xấu của bạn đến môi trường càng mạnh, tựa như một dấu chân khổng lồ in lên bề mặt trái đất vậy.
Theo như lý tưởng mà nói, thì khi một người nhìn thấy con số dấu chân carbon của mình và nhận ra cách sống của họ ảnh hưởng đến trái đất nhiều đến mức nào, họ sẽ bắt đầu thực hiện những thay đổi để giảm số dấu chân carbon của mình.
* I. New words:
Carbon footprint (n):
Produce (v):
Carbon dioxide (n):
Non-renewable (a):
hydro (n):
Use up (v):
Run out (v):
Dấu chân các bon
Thải ra
Các bon điôxit
Không thể hồi phục
Nước
Dùng đến hết
Cạn kiệt
Solar panel (n):
Pin mặt trời
Carbon footprint thải ra
hydro cạn kiệt
produce pin mặt trời
use up dấu chân các bon
run out các bon điôxít
solar panel dùng đến hết
non-renewable nước
carbon dioxide không thể phục hồi

1.Carbon footprint is in the news a lot these days
2. It’s better to have a bigger footprint
3. Non –renewable energy sources like coal , natural gas ,and oil .
4. Mai thinks , she has a big carbon footprint

Activity 1 : Listen and repeat
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 producea lot of carbon dioxide .Those sources are going to run out soon too
Nam : So , they`re different to wind , hidro, and solar ?
Mai : Yes , they`re all sources of energy too ,but they`re renewable .That means they can use them all up - They will last forever .
Nam :Do you have a bid carbon footprint , Mai ?
Mai : Mine`s small. I recycle the products I use and I go everywhere by bike .We have solar pannals 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!

1. What is a carbon footprint ?
2. What does ‘non renewable energy’ mean ?
3. Why is sunlight a renewable resource ?
4. Why does Mai think she has a small carbon footprint ?
5. What things do you think might create a big carbon footprint ?
a. Answer the following questions
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 energy because we can’t use it all up , it will last forever
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 product carbon dioxide might create a big carbon footprint
