ONCE more, I will try to put N Taylor on the right track. Mr Taylor knows perfectly well that I am referring to the density of population of the UK, while he persists in referring only to an integral part.

If the possibly calamitous changes now, undoubtedly, taking place on the planet are, indeed, caused by human factors, then it makes no difference where the 6.25 billion humans are located on the planet. Presumably, each individual will continue to cause greenhouse gases and global warming wherever he/she lives.
