| Climate, more than any other single
factor, determines the distribution of life on earth. Climatic boundaries

Others, such as bears are flexible enough to adapt to a broad range of climates.

It is said that the Englishman objects to this type of existence, but if the case is such, he does in fact differ from the inhabitants of most countries of the world today. In the past our own blocks of fiats have been associated with the lower-income groups and they have lacked the obvious provisions, such as central heating, constant hot water supply, electrically operated lifts from top to bottom, and so on, as well as such details, important notwithstanding (然而), as easy facilities for disposal of dust and rubbish and storage places for baby carriages on the grounds for washing. It is likely that the dispute regarding flats versus individual houses will continue to rage in for a long time as far as Britain is concerned. And it is unfortunate that there should be hot feeli
