and I have no choice but to react to this, the point that is being made made is unnecessary journeys, it is reckoned there is 150 years of oil left (give or take) though the fall out of it running out will be felt long before that.
I know someone shes 2 1/2 years old her grand children will be living in a world without crude oil, now hopefully we as a species will have found better ways to create the energy we need by then, (and don't get on about energy efficient cars as most of these are still powered by fossil fuels from power stations)
Just take a look at this chart though I suspect many on here don't really needed to.

Today we are peaking at over 400ppm CO2 the release of methane is now becoming an issue this has also increased and is 4 times as potent as CO2 as a green house gas, the global mean temperature fluctuates for many reasons, but the chart clearly shows the that the increase has been rapid since the 60's an increase in car ownership increase in unnecessary global travel increase in electrical consumer products both in use and manufacturer I could go on, the point is are we to remain selfish or think about the future for our grand children and theirs or continue as we are, it us that will make the difference not governments.
However I do feel it is too late, the rate of glacial melt is unprecedented and sea level rise is currently at a mean of 0.4mm a year or which means a place I ride through not 5 miles from here could be on the coast (10m a.s.l.) within 200 years, the current coast line is some 45-60 miles away.

Leisure driving has no effect, please do go pull the other might even make me laugh, and I haven't even started on plastics and their possible effect on insect life,
