So, why cycle?
But I have a car, so why would I want to cycle anyway?
...and I'm sure there are loads of other reasons to just stick to the car: anyway, China and India pollute more with their industries than I'm ever going to save with the small amount my car makes so why should I bother?
Surely it would take lots of people to change to make even the slightest difference?
Yes, you are probably right, it would, so really we're all just wasting our time and we may as well continue happily doing what we like!
It's true that switching to a bike may, in itself, not save the Planet. But this is not the only reason to make a change.
...and we can make a small difference which, together with all the others, may go some way to making change.
We need to think about living more sustainably and not just continue to take, take take!
If we all do nothing, then nothing will change: if some of us do something, then something may change.
