Hwever, nly a few hurs later, she tk me ut f the fridge and drank the water inside me. Then she threw me int a dustbin. I have never felt s empty and alne in my life.Early the next mrning, a man tk me ut f the dustbin. He threw me and the ther rubbish in t the back f a truck. There were s many hrrible smells. Then I was pushed tgether with the rest f the rubbish. Sn I was cmpletely flat. I cannt believe hw thin I became.

Yur carbn ftprintThe ttal amunt f carbn dixide (CO2) yu prduce a year is called yur carbn ftprint. Besides breathing, there are tw ther ways yu can prduce CO2. First, yu can d it directly, by driving a car r using a gas stve. Secnd, yu can d it indirectly, by buying r using prducts that prduced CO2, when they were made.
Generally, yu shuld make yur carbn ftprint as small as pssible. Fr example, yu can use public transprt instead f a car, r yu can walk r cycle.
Answer the questins
1. What des carbn ftprint mean?It refers t the ttal amunt f carbn dixide that ne prduces a year.2. Hw many ways ne prduces CO2 are mentined in the text?Three.3. Hw t prduce CO2 directly? By driving a car r using a gas stve.
4. Hw t prduce CO2 indirectly? By buying r using prducts that prduced CO2, when they were made.5. What shuld we d t reduce ur carbn ftprint?Use public transprt instead f a car, r walk r cycle.
What ther things can yu d t reduce yur carbn ftprint?Suggested answer:1. Take a shwer: Taking a shwer uses abut 1/5 f the energy as taking a bath, and as lng as yu dn’t fall asleep it shuld use less water t. If nt, yu can always install a “lw flw” shwer head t limit the amunt f water being used.
2. Unplug yur phne charger: When yu’re nt using it that is. Accrding t the U.S. Department f Energy, appliances cnsume a significant amunt f electricity even when they are switched ff. Ever ntice hw yur phne charger can get ht with n phne n it?3. Buy a laptp instead f a desktp: Laptps can use up t 80% less energy than a desktp, and unless yu are a die hard tech junkie that needs t have the fastest prcessr n the planet, a mdern laptp will suit yur needs just fine.
4. Avid black trash bags: Because f the black pigmentatin these trash bags cannt be recycled. A better ptin is t use white trash bags and the best ptin is f curse…nne.5. Filter yur wn water: This ne is huge. Mst tap water (in western cuntries) is safe t drink and by filtering it yu can d a lt f saving. First f all, the water is usually flwn in frm far away which requires fuel and then the packaging itself uses a lt f energy. Besides, buying bttled water nly feels gd until yu check yur bank accunt.
6. Buy lcal: Once again, if yu keep things lcal it will reduce the amunt f fuel that is required t get the fd frm the farm t yur fridge. The same cncept ges fr ther gds and services as well.7. Replace lightbulbs with CFL bulbs: CFL (cmpact flurescent) bulbs can last up t 15 times lnger and use up t 8% less energy than regular lightbulbs. Again, this culd certainly have the added benefit f streamlining yur electric bill.
8. Use rechargeable batteries: Using rechargeable batteries can shave almst 1,000 punds ff f yur carbn ftprint by the time the batteries die fr gd.9. Read the newspaper nline: This ne is a n-brainer. By getting yur daily fix f news nline rather than in print yu are saving a lt n paper printing csts.10. Drive a hybrid: Althugh they run a little pricier, ver the lifetime f the vehicle yu will find yurself mre than cvering the difference in gasline savings.
