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.
To reduce your carbon footprint, we should reduce our electricity bills by turning off the light before going to bed or going out. Moreover, we should use low energy light bulbs. We can also use public transports more often and reduce the use of fossil fuel.
Dịch: Để giảm lượng khí thải carbon của bạn, chúng ta nên giảm hóa đơn tiền điện bằng cách tắt đèn trước khi đi ngủ hoặc đi ra ngoài. Hơn nữa, chúng ta nên sử dụng bóng đèn năng lượng thấp. Chúng ta cũng có thể sử dụng vận tải công cộng thường xuyên hơn và giảm việc sử dụng nhiên liệu hóa thạch.

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.
2)The secodt most inportain lifestyle change is to eat less meet with particula emphasis on meals containing beef and lamp .Cows and sheep emit large quantitines of methane ,a power ful glublewarming gas.Avegan diet as much as a 20%difference to your overal carbon impart simply cutting or beef will deliver a significan benefit on it own

1. There are 10 types of energysources. They are: solar energy, wind energy, geothermal energy, hydrogen energy, tidal energy, wave energy, hydroelectric energy, biomass energy, nuclear power, fossil fuels ( coal, oil and natural gas).
2. I can use less electric, use more natural energy,...
3. Renewable energy means the energy never exhausted such as solar energy, wind energy,...
4. I think my carbon footprint is medium.
5. Yes, I have.
You know the feeling. You just gulped down a bottle of water and now the empty plastic bottle is taking up your only free hand. The once refreshing water bottle is now a nuisance, and you just want to get rid of it. Seeing no recycling bins in sight, you now have a moral dilemma: Do you throw the bottle into the trash or do you hold onto it for who-knows-how-long until you find a recycling bin?
I think we all know the right answer in this situation, but let's be honest, students aren't always as... thoughtful (source: I once was a teenager, too). To avoid plastic bottles and other miscellaneous recyclables sitting in a landfill, place recycling bins next to trash cans and in strategic places throughout campus. Your future great-grandchildren will thank you.
People are living longer so there are more elderly people .Many young people are doing community service .They help elderly people .They do their shopping .They do their housework.They clean their yards.They even paint their hoyses.
Last summer vacation, i went to visit Yen Bai where has many poor people. I went to with my teachers and my friends. We donated clothes for old people and pens, books for street children. We also tided their house. My teachers cooked food. All people at here were very happy. And we felt happy, too. We hoped that we could make a small change for them.
it about 37 to 38 cm
we should play outside more because if u always play game your eyes can hurt
was born in Hochiminh City. For four years, i have been away from home and studied abroad in Finland. However, the memories of Hochiminh City are still vivid in my mind. My thought wanders from busy crowded streets to quiet orchards beyond downtown.
Everything seems colorful and quite pretty to me. I have been dreaming about the taste of local food and the smell of steaming buns or sticky rice everyday of my life while i was studying or working abroad.
I wish i could come back and enjoy any dishes made by my mother. One more important thing about this city is because i had met my future husband, that fulfilled my life and completed it thouroughly. To me, every tiny things involved in my city become my soul and dearest memories ever.
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.
