10 things you can do

I received this email from the firm yesterday, about global warming, about the Earth Day.

* Change a light
Replacing one regular light bulb with an energy-saving light bulb will save 67.5kg of carbon dioxide a year.
* Drives less
Walk, bike, carpool or take mass transit more often.
* Recycle more
You can save 1,080kg of carbon dioxide per year by cycling just half of your household waste.
* 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!
* Use less hot water
It takes a lot of energy to heat water. Use less hot water by installing a low-flow showerhead.
* Avoid products with packaging
You can save 540kg if you cut down on your garbage by 10%.
* Adjust your air-con
Moving the thermostat just 2° can save about 900kg of carbon dioxide a year.
* Plant a tree
A Single tree will absorb over a 1,000kg of carbon dioxide over its lifetime.
* 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.
* Watch An Inconvenient Truth on HBO
Catch what former US vice-president Al Gore has to say about the state of planet Earth and share it with your friends.
