3 pm: You've got mail
Almost 240 kilograms of fossil fuels are burned to make just one desktop computer. The manufacturing process itself consumes 22 kilograms of chemicals and 1.5 tonnes of water. Building a computer is a particularly energy-intensive business. It is around 10 times less efficient than building a car or a refrigerator. A single memory chip uses 700 times its own weight in fuel during construction
What you can do:
You can donate your old computer to your school, a friend, or an NGO.
Don't leave your computer running for 24 hours a day. Always switch off the monitor when you are done with work. It's been estimated that you can laser print 800 pages with the energy you waste by leaving your monitor on overnight.

8 pm: Going home
Short journeys by car are damaging to the environment. Engines use more fuel in the first few kilometres of driving, than later in the journey.
Cars continue to damage the planet when they are scrapped. Thousands of tonnes of metal, glass and plastic is wasted instead of being reused or recycled.
What you can do:
Public transport in your city will get you around faster and at a fraction of the cost to the environment.
Reuse your tyres. They can be used to replace the tread on the surface of other tyres, shredded to surface sports grounds and also burned in kilns instead of coal to make cement. This creates fewer greenhouse gas emissions and leads to less waste being buried.

9 pm:  Cleaning up
Anti bacterial sprays and bleaches can lead to the evolution of antibiotic-resistant bacteria. The sprays kill weaker bacteria, leading to natural selection of stronger, more dangerous variety.
Chlorine bleaches are caustic, and when they travel from your drain into water bodies, they produce cancer causing chemicals called dioxins.
What you can do:
You can make your own cleaning liquid. Diluted white vinegar, lemon juice and baking soda can be used separately or together to clean a variety of surfaces, windows and tiles. Rather than a synthetic furniture polish, use a mix of olive oil and vinegar to give a shine to your furniture.

10 pm: Me time
If you switch off your electrical equipment at the mains every time you finish using it, you could save millions of tonnes of fuel. More people are choosing to receive digital and satellite TV for a greater choice of programmes. The set-top boxes are always switched on, or left on stand-by. They draw electricity all the time and therefore, waste energy.
What you can do:
If your equipment breaks down, check if it can be repaired before deciding to buy a replacement. Flat-screens TVs are usually bigger than conventional TVs, and use more energy, but ironically, are often most efficient. Liquid Crystal Display (LCD), for example, uses less energy than similar size CRT models.    
Save energy by spending one evening a week not watching TV, or listening to your stereo. Instead, spend time with your family or read a good book

11 pm: To bed
Many bathroom products, including toothpaste and shampoo, contain palm oil. In order to establish palm oil
plantations, the rainforests in Malaysia and Indonesia are being chopped. This has caused the Orangutan population to crash in the last 15 years. About 5,000 Orangutans die every year.  
About 60% of tissue products, such as toilet paper and face tissues, contain zero recycled fibres. Recycled fibres are made from office paper; they are scrubbed and washed many times before they go into the papermaking machine.
What you can do:
Don't leave the tap running when you brush your teeth. Use a glass or mug of water, instead. If you haven't got a toilet with a water economy flush, place a brick in your toilet cistern so that toilet uses less water per flush. 
Avoid using tissue if you can. Carry a napkin or handkerchief.
