Sheep naturally inhabit areas that are high and dry. The animals, however, will thrive on any land except that which is wet and swampy. The fine-wool breeds of sheep especially exhibit a preference for the lands that are drier, whereas there are one or two of the British breeds that are particularly adapted to the lowlands. The industry of raising sheep has been carried on with success in areas that have tropical temperatures with low rainfalls, but rearing the animals in regions of high temperatures and high rainfall has not been generally successful.
