little efforts for the environment

1. Change a light- replacing one regular light bulb with an energy-saving light bulb will save 67.5kg of carbon dioxide a year.
2. Drive less- walk, bike, carpool or take mass transit more often.
3. Recycle more- you can save 1080kg of carbon dioxide per year by recycling just half of your household waste.
4. Pump up your tyres- keeping your car tyres inflated properly can improve petrol mileage by more than 3%. Every 4.4 litres of petrol saved keeps 9kg of carbon dioxide out of the atmosphere!
5. Use less hot water- it takes a lot of energy to heat water. Use less hot water by installing a low-flow showerhead.
6. Avoid products with packaging- you can save 540kg if you cut down on your garbage by 10%.
7. Adjust your air-con- moving the thermostat just 2 degree Celsius can save about 900kg of carbon dioxide a year.
8. Plant a tree- a single tree will absorb over a 1000kg of carbon dioxide over its lifetime.
9. Turn off electronic devices- switching off your TV, DVD player, hi-fi set and computer when you're not using them will save you thousands of kilogrammes of carbon dioxide a year.
