Would love to be able to use a bike, no more insurance, no more vandalism, no more sat in traffic jams, no more washing the car, however getting to liverpool or sheffield to earn a living means transport. Bikes are an option only for people who don't need to transport things or live close to their work. Apart from the arguable use of raw materials to make the car, fossil fuels have been the most damaging area, bio-fuels are the way forward. It is not just travel, the heavier fats that are not suitable for cars can be used in generating electricity. Someone is already setting up 4 megawatts of plant! There are also bacteria that can produce oil as a waste product! there are so many ways forward that are ecologically sound. Fossil fuels will only get more expensive and run out in the long run, we will have to use the alternatives eventually so why not now?
