How do we realize a "low-carbon life" in our daily life? The fifth doctoral thesis on world geography

Once, the abundant energy left by Mother Earth made us complacent and lamented that the energy on the earth was inexhaustible. However, since19th century, people have been accelerating the pace of industrialization and urbanization. The global environment in which we live is deteriorating, glaciers are beginning to melt, sandstorms are year after year, extreme weather is frequent, and rare species are decreasing day by day. The Wenchuan and Yushu earthquakes made the whole Chinese nation cry and broke our hearts. Iceland's volcano erupted strongly in the Atlantic Ocean, covering the whole of Europe with smoke and dust. Hugo, a great French writer, warned us a long time ago: "Nature is a kind mother and a cruel butcher." The embankment of a thousand miles is broken in the ant nest, and there is only one earth for human beings. Any break in the ecological chain will bring irreversible disaster.

Mother Earth groaned in pain. Angered, a wave of snow fell here, and it turned into ice and snow. Last year's snowstorm in the south and this year's snowstorm in Xinjiang touched the hearts of countless compatriots. She took a deep breath there, and the heavy rain poured down, flooding many farmland and buildings, and mudslides made trees disappear in a large area. The world is getting warmer, and the glaciers in the Antarctic and Arctic are melting with tears like being baked by fire. I even saw the polar bear sitting on a small piece of ice curled up into a ball, holding a small pholiota adiposa in his hand, which looked pitiful. Yes, the "El Nino" phenomenon has brought great pain to our mother earth.

Therefore, in order to protect our homeland, we must actively join the ranks of environmental protection, call on more people to take action, actively practice low-carbon life, and start with saving electricity, saving solar terms, saving water, rational utilization and recycling. The so-called low-carbon life refers to minimizing the energy consumed in daily life, thereby reducing carbon, especially carbon dioxide emissions. In fact, living a low-carbon life is very simple: 1 Choose an energy-saving air conditioner, turn it on once in summer and turn it down once in winter. All the light bulbs in the house were replaced by energy-saving lamps, and the good habit of turning off the lights was also developed. Use solar water heater to save electricity and gas. Choose an energy-saving washing machine, and the water for washing clothes can be recycled. Ride more bicycles, travel less by car, use more environmental protection bags and so on.

■ "Low carbon" proposal

It is easy to prevent global warming. Isn't it easy to turn off unnecessary lights? In fact, we often forget this. Turn off the lights during the day or less, try to have activities in the same room at night, and turn off the lights when entering and leaving the house ... If you want to join the "low-carbon life" group, please take a look at the following suggestions.

● Turn off the computer in time.

Statistics show that 75% of the electricity in the home is spent on keeping the TV, computer and stereo on standby. On average, a desktop computer consumes 60 to 250 watts a day. If a computer is used for 4 hours every day and turned off at other times, it can save about RMB in 500 yuan and reduce carbon dioxide emissions by 83% every year.

● Take more buses.

Carbon dioxide produced by transportation accounts for more than 30% of greenhouse gas emissions, and one of the best ways to reduce such emissions is to take buses. According to the data of American Public Transportation Association, public transportation saves nearly 5.3 billion liters of natural gas every year, which means that it can reduce carbon dioxide emissions by 6.5438+0.5 million tons.

● Pay bills online.

Online banking and billing operations can not only save trees, avoid driving to the bank and emitting unnecessary carbon dioxide on payday, but also reduce the energy consumption of paper documents during transportation.

Choose a small house

People yearn for big houses, but big houses will increase carbon emissions invisibly and need more energy for heating and cooling. Taking heating as an example, a big house needs to consume a lot of energy to maintain its temperature. The bigger the house, the greater the impact on the environment. At present, every household in the United States emits an average of 18 tons of greenhouse gas every year, consuming a lot of fuel and non-renewable energy.

● Abandon the steak.

According to the data of the United Nations, the greenhouse gases emitted by the global meat processing industry account for 18% of the total emissions, even exceeding the transportation industry. There are/kloc-0.5 billion domestic cattle and bison,/kloc-0.7 billion sheep and goats on the earth, and their numbers are still growing rapidly. If you become a vegetarian, your annual carbon dioxide emissions will be reduced by about 1.5 tons.

● Open the window.

We emit about 25 tons of carbon dioxide per capita every year. How can we reduce this number? There are some simple and effective methods: opening windows instead of indoor air conditioning; When air conditioning is used in summer, the temperature rises slightly by several degrees. Statistics show that as long as everyone turns up the air conditioner by one degree, the country can save 3.3 billion kWh of electricity every year.

● Hang the clothesline.

Research shows that 60% of the "energy" of a garment is released in the process of cleaning and drying. It should be noted that warm water should be used when washing clothes, not hot water; After washing clothes, hang them on the clothesline to dry naturally. Don't put them in the dryer. In this way, you can always reduce your carbon dioxide emissions by 90%.

● Bring your own shopping bag.

More than 500 billion plastic bags are consumed worldwide every year, of which less than 3% can be recycled. Plastic bags are all made of polyethylene, which will take thousands of years to biodegrade after being buried, and during this period, harmful greenhouse gases will be generated. Don't forget to bring your shopping bag when you go to the grocery store next time.

● Plant a tree.

When it comes to global warming, don't be alarmed if you don't know the complicated carbon capture (CCS) technology. In fact, the experts who "capture" carbon dioxide are the trees themselves. If you think it's too much trouble to plant trees yourself, you can at least donate money to environmental protection organizations and ask them to help you.

Dear students, many a mickle makes a mickle. Work in the present, benefit in the future. A trickle can make a surging river. Green leaves can make up a vast forest. For our beautiful earth home, for the green hills, blue seas and blue sky left for future generations. Let's go into low carbon, start a new life of environmental protection, and work hard to create a green home for * * *!
