10 trifles to arrest global warming Global warming—the negative consequence of greenhouse effect—is increasingly grim, which has been illustrated by a succession of destructive crises in temperature. But how can we arrest global warming? The following are some plausible suggestions: 1. energy-saving lamps instead of common bulbs Install the energy-saving lamp at home, which only need 40% of the amount of energy to keep the same lightness as the common bulb. That is to say, 150 kilograms of carbon dioxide (CO2) could be reduced to release into the air every year. In addition, extinguish the bulb in corridors during daytime, or else, the electricity they consume would multiple in vain. 2. Clean the air-condition and change the filter stuff regularly By doing so we could shrink the output of CO2 by 16 ounces (namely 1 pound) every day. 3. Put the lid on when cooking It is a valid manner to prevent the outgoing of vapo(u)rs. When the water in the kettle boils, please turn off the power speedily. 4. Reject the imported food It is estimated that the domestic food save 70% of freight compared with foreign food. East less manufactured food, which could indirectly withdraw the CO2 in the air. In addition, use your handkerchief and make a reduction in using napkins. 5. Eat less meat Eat a few more raw vegetables such as carrot, cabbage, onion and so on. Nitrogen, which could be released by many domestic animals, is an important component of the mixture of greenhouse gases. 6. Make a wholly denial of using plastic bags Most of plastic bags couldn’t easily be dissolved by germs and bacteria in soil, so go shopping with your own handbag. 7. Reform homes to be warmer Plug some rubber stuff in window rips or paste up some isolated materials on exterior of window glasses, which would avail to prevent external cold and heat. 8. Recycle organic rubbish Don’t dump organic rubbish, which could produce energy through disposal. 9. Try not to drive private cars With the evolution of transportation, traveling by subways or collective cars are no longer supplements of going around. They are good matters for protecting the environment and saving energy. 10. Take less aircrafts (airplanes) When you make a journey, please choose to take a train at least one or two times in a year, which would be helpful to reduce the CO2 in the air. Of course, reducing the weight of your luggage before going aboard is also worthy to dry. Naturally, sending the messages to others also might help to arrest the global warming.
