The Ozone layer is something I'm not convinced about either. Perhaps the hole in the Ozone layer has always been there we just didn't know about it until the advent of space satellites and computers.

I'm more concerned on a local level. In the centre of our town there are so many "traffic calming" schemes that cars end up crawling or sitting stationary - and it stinks. We definitely have too many cars, lorries and buses on the road. Parking space is at a premium - and it's expensive. Getting to work on my bike is so much easier too. It takes a maximum of 16 minutes to get to work as opposed to anything up to 35 minutes in the car. 35 minutes to go 2 1/2 miles Even going home is quicker by bike as in the car at peak periods you end up stuck in a bottle-neck and it can take 45 minutes for the same journey. 20 minutes maximum by bike (and I hope to knock a few minutes of that time as I get fitter). If hubby drove the car from our place of work and I took the bike, I'd have his cup of tea waiting for him by the time he got home LOL.

In my house I switched to energy saving bulbs a long time ago for two reasons. 1. They work out cheaper. 2. They last much longer than conventional bulbs. Using them does have a knock-on effect for the environment too.

It does frequently cross my mind that by using my bike I am helping the environment in a small way but I'm still not convinced about the hype on Global Warming. It is a natural phenomena that's been around since time began. I just think it's being exploited to clobber ordinary people with taxes they can not afford, certainly in this country.
