Some good answers above. Here’s my contribution…

The primary cause of manmade global warming is heat from the sun being trapped by greenhouse gases. The main greenhouse gases are carbon dioxide, methane and nitrous oxide, the largest contributor is CO2. It’s this gas that many individuals and organisations are taking steps to reduce emissions of. Here are some practical steps you can take to combat global warming.

AT HOME AND WORK
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
? When replacing appliances buy energy efficient ones.

? Turn off electrical appliances when not in use, don’t use the standby option.

? Use energy efficient light bulbs and switch off lights when not in use.

? Similarly, turn down water heating by a few degrees.

? Fit individual thermostats to radiators and don’t heat rooms that aren’t used.

? Insulate walls, lofts, hot water tanks and pipes.

? Turn your heating and air conditioning down, a small difference will be barely noticeable.

? Sign up to a green energy supplier, one that produces energy from renewable sources.

? Turn off heating and air-conditioning when the house or office is unoccupied.

? Wash full loads of clothes at a lower temperature, modern machines and detergents are just as effective at lower temperatures.

? Dry your clothes outdoors instead of in a tumble drier.

? Wash full loads in the dish-washer.

? Insulate your home and block draughts around doors and windows. In Europe this is free to many people.

? Consider installing a renewable energy system such as solar panels or a home wind turbine.

? Use rechargeable batteries; don’t leave rechargers on for longer than is needed (including mobile / cell-phones).

? Boil only as much water in the kettle as you need.

? Buy locally produced organic food where possible, there’s less transportation and the farming methods are more environmentally friendly.

? Look where goods were manufactured and avoid buying those that have been flown or shipped long distances.

? Recycle and reuse as much as possible. Sign up with mail preferential services to stop junk mail.

? Avoid buying products with excessive packaging.

? Don’t have your fridge or freezer set lower than need to be, regularly defrost freezers, don’t put hot food into your fridge or freezer.

? If your fridge or freezer is over 15 years old then consider replacing it (check with local authority regarding disposal of old one).

? Work from home where possible.

? Eat less meat and dairy produce, farming produces large quantities of greenhouse gases.

ENERGY EFFICIENT TRAVELLING
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
For many people a substantial reduction in greenhouse gas emissions can be achieved by driving a more fuel-efficient vehicle. Each gallon of gasoline burned produces 10kg (20 pounds) of carbon dioxide.

? Drive a fuel efficient vehicle, if you have more than one vehicle then use the most economical one more often.

? Consider walking or cycling when going to work or taking the kids to schools, if you have to drive then consider car sharing.

? Use public transport where possible and consider taking a coach or train instead of using domestic flights.

? When replacing your vehicle look at diesel and liquid petroleum gas models.

? Combine multiple journeys into one and do your weekly shopping in a single trip.

? Stagger journeys where possible to avoid rush hour traffic and hold ups.

FUEL SAVING TIPS FOR DRIVERS
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
By driving carefully and keeping your vehicle in good condition you can save up to 30% on your fuel bills and cut greenhouse gas emissions at the same time. Below are some tips for increasing fuel efficiency, there’s more information on the Eartheasy Website – http://eartheasy.com/live_fuel_efficient_driving.htm

? Avoid harsh braking, accelerate gently and drive at a steady speed.

? Keep tyres inflated to the correct pressure.

? Remove bike and ski racks when not in use, also remove detachable roof racks, luggage boxes etc.

? Carrying unnecessary weight wastes fuel, declutter your vehicle.

? Use the correct gear and use cruise control if your vehicle has it.

? Keep your vehicle regularly services.

? Turn the engine off when stopped or waiting.

CARBON OFFSETTING
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Carbon Offsetting is one way to reduce or eliminate your carbon footprint, in most cases this involves calculating your greenhouse gas emissions and planting trees so as to absorb an equivalent amount of carbon dioxide. Some websites where you can calculate your carbon footprint and purchase offsetting are…

Our environment doesn’t need your help. It’s fine on its own. Go do something productive.

The best we can do as individuals is be more responsible ,in our own neck of the woods
Organize well publicized clean up parties ,talk on the radio
Have citizan meetings
Get the schools involved to plant trees and listen to environmental awareness talks,

If you do any cleaning up leave signs behind saying who cleaned,why and ask people not to start dumping rubbish again ,leave a hole or bins ,in case people come with trash ,

POSITIVE ACTIONS)
Classify trash take out all the organic waste and make compost with it ,the worst you can do is throw it with the trash
70% of contamination is due to organic waste that is mixed in with the garbage .
And it is just as bad in the sewer where it helps to breed rats and in the landfill it poisons the ground

And it is the easiest to take care of
o first of all we have to classify trash at least keep the organic to one side ,like in a plastic bin with a lid
If you got a few meters of ground ,you only need 1 or 2 square meters in a shallow hole ,in the shade ,that you can wet now and again ,where you dump everything that is organic ,from toilet paper,bones vegetable cuttings ,eggshells,,excrement ,and cover regularly with leaves to keep humid and to hide any smell
the worms will come and decompose the wastes turning it into beautiful black soil for the garden of flower pots .
If you are in a apartment ,if you have a balcony get a big plastic bin drill some holes in the side and lid ,
Add a few buckets of sand now and again to put over the trash ,you should really stir or move the stuff at times to aerate it and ensure that the decomposition is overall ,keep moist
This rubbish does not get big very fast and the thing works for a long time with out getting full

If you want to help the planet ,plant a tree every week ,if everyone on the planet did we we would be able to slowdown the destructive processes
Reduce carbon emmisions,and they are already working on that by alternative forms of energy and regulations on carbon producing materials,aerosol cans,burning rubbish,industrial chimneys,power plants etc.
Water harvesting projects ,such as millions of small dams.to redirect over ground water flows from the rains into the ground to supply sub teranian water supplies.
The protection of existing forests.
Stop building more highways,urban planning to include vegetation stop building cities encourage people to return to the land to conduct their business from there which now has become possible thanks to the internet.
Education to motivate people to auto sufficiency by building more home food gardens.
Education on environmental awareness
education on family planning to curb over´population
Agricultural education and improvements to follow the principals or sustainability and soil management.
More environmental or land ,design to prevent bush fires,such as–fire breaks
More dams.regulations and control for public behaviour
Alternative efficiant public transport to discourage the use of the internal con bustion engine

Demonstrate your environmental consciousness by following Al Gore around the country in your private jet.

1)Buy energy efficient bulbs
2)Walk more or use a peddle bike
3)Dont use shampoo or shower gels, stick to old fashioned soap
4)Dont leave anythin on standbye
5)Turn off the main fuse to ur house at night
6)Recycle
7)Make ur own fertilizer using human urine, faeces and plant waste(sounds disgusting but isnt bad at all cos all the bacteria die off pretty quickly)
8)Turn off the tap when your not rinsing ur toothbrush
9)Take showers not baths(and for that little bit extra try to take it warm not hot)
10)If you take a bath then use a bucket and pour most of the water onto ur lawn or into ur plants
11)Dont pour bleach down the toilet or any other chemicals for that matter
12)Dont smoke
13)Dont each as much meat, it causes our bodies to produce methane (farts) which is far worse for causing the green house effect than CO2
13)Dont use paper…just type
