From Euan Connell, Aberdeen, UK
I just read your feature about Earth's rubber supply (18 May, p 44). As someone with allergies to latex and the accelerators used in rubber production (carba mix and thiuram mix), the prospect of a world without rubber seems fantastic. I think this should serve as a wake-up call that we have, yet again, become too dependent on a finite resource and alternatives should be considered. My view may be biased, but I don't think it is unjust. The rubber particles end up in our atmosphere and it could be contributing to the rise in allergies. Pollution is never a good thing.
