Dubai good, plastic bags bad

Letters

Charlie Scrimgeour is right to highlight Dubai's stability and tolerance as shining lights in the Middle East (NCE 7 September). However, how long will its prosperity continue when the oil runs out in just a few generations' time?

Perhaps this hinges on the ability of air and sea transport to move away from petroleum, currently driving Dubai's economy. With global warming, Dubai's coastal desert cities will only require more resources to support habitation - hopefully engineers can rise to this manmade challenge.

To me, sustainability is not black and white but an ever increasing scale, hinging on our ability to utilise renewable energy sources while maximising the reuse of resources.

Take plastic bags. If every NCE reader reused their bags for every other weekly shop, in five years' time 22.3M bags would have been saved - roughly the equivalent energy of 2.6M car kilometres. Check out www. banthebag. org. uk.

As the cliche goes, every journey starts with a small step? Robin Campbell (G), 24 Lewis Street, Cardiff
