Each and every one of us is responsible for the greenhouse        nts should the need arise-as it almostpected, and is prepared to   tion, something es along to gases we give out in our daily actions and choices．Therefore，bating climate change is going to take the bined efforts of everyone on the planet．
The average household carbon footprint in China is 2.41 tons of carbon dioxide annually．That's enough to fill half an Olympic swimming pool．
Surprised? Well,．here's how you can work to reduce it：
1．Take showers rather than baths and reduce your shower time by two minutes．This will save water and give you an extra two minutes in bed．
2．Don't purchase unnecessary clothes，and be careful about the materials you buy．Wool and cotton have a really high greenhouse gas impact．Manmade fibers are a better choice．
3．Try to buy high-quality，long-lasting products even though they    ．A laptop is more efficient than a desktop，and a small screen TV is better than a big flat-screen．
4．Only turn the water heater on when necessary，and adjust temperature controls to avoid overheating．Put a lid on a pan when boiling water．
5．When using the washing machine，be sure there's a full load and turn the temperature down if it's not really dirty．
6．The greediest home device along with the washing machine is the fridge．Make sure it's as efficient as possible by keeping it out of direct sunlight and away from the oven or heater．Don't put food in when it's still warm．
7．Only buy the amount of food you need and if there are leftovers，get creative．For instance，make them into a soup．Ask to take food home from restaurants if there's some left，but remember to take your own container to avoid using a disposable carton．
