1)air trevel is usually the largest component of the cacbon footprint of frequent flyers .A single return flight from london to newyork -including the complicated effect on the high atmosphere - contributes to alsmost a quarter of the average person's annual emissions.The easiest way to make a big difference is to go by train or nat take as many flights.

There are several things we can do to reduce our carbon footprint:

(Có một số điều chúng ta có thể làm để giảm dấu chân carbon của mình)

- Consume local and seasonal products

(Tiêu thụ các sản phẩm địa phương và theo mùa)

- Bring reusable shopping bags and avoid products with excessive plastic packaging

(Mang theo túi mua sắm có thể tái sử dụng và tránh các sản phẩm có túi nilon quá nhiều)

- Make sure to buy only what we need, to avoid waste

(Đảm bảo chỉ mua những thứ chúng ta cần, tránh lãng phí)

- Buy responsibly-made clothes, e.g. made from recycled material or with an eco-label

(Mua quần áo được sản xuất có trách nhiệm, ví dụ: làm từ vật liệu tái chế hoặc có nhãn sinh thái)

- Turn off the water while we brush our teeth or do the dishes

(Tắt nước khi chúng ta đánh răng hoặc rửa bát)

- Unplug our electronic equipment and don’t leave our phone on charge when the battery is already full

(Rút phích cắm thiết bị điện tử của chúng ta ra và không sạc điện thoại khi pin đã đầy)

- Limit and recycle our waste

(Hạn chế và tái chế chất thải của chúng ta)

→Natural Gas← viết về cái nè nhé
A natural gas flame

A gas that is made up mostly of methane and found near other fossil fuels, like coal. Methanogenic processes occurring in landfills and marshes also produce natural gas. Like petroleum, natural gas must first be processed before we can use it as a fuel. It is important to remove most of the other components of natural gas until it is almost purely methane. When combusted, natural gas produces only about half the greenhouse gas emissions as coal does, making it a popular fossil fuel in our increasingly carbon-conscious society. Take a look at these oil- and gas-related maps (link is external) to learn more about natural gas production and reserves in the United States.

XV. Read the passage and answer the question.

A carbon footprint is the amount of carbon dioxide (CO2) released into the air by your own energy needs. You need transportation, electricity, food, clothing, and other goods. CO2 is produced by the burning of fossil fuels which is used to provide energy for your homes, by the cars you travel in and by the manufacture and transport of goods you buy.

Carbon dioxide is also called greenhouse gas, which causes global warming. That is the reason why the carbon footprint is a very poweful tool to understand the impact of personal behaviours on global warming. If you want to contribute to stop global warming, the reduction of your personal carbon footprint is essential. Fist, you can reduce your carbon footprint by driving less. When possible, walk or ride a bike to avoid carbon emissions completely or use public transport in order to decrease CO emissions. Second, support using clean energy sources such as wind, solar, geothermal energy and biogas. Finally, reusing or recycling items you no longer use is also a good way to reduce your carbon footprint.

1. What is a carbon footprint?

A carbon footprint is the amount of carbon dioxide (CO2) released into the air by your own energy needs.

2. How is CO2 produced?

CO2 is produced by the burning of fossil fuels which is used to provide energy for your homes, by the cars you travel in and by the manufacture and transport of goods you buy.

3. What can carbon footprint cause?

It can cause global warming.

4. What should you do to stop global warming?

Driving less, supporting using clean energy sources such as wind, solar, geothermal energy and biogas.
