Carl Sagan has entertainingly described this phenomenon, musing about the destiny of bacteria that reproduce by dividing into two every 15 minutes. Says Sagan:"That means four doublings an hour, and 96 doublings a day. Although a bacterium weighs only about a trillionth of a gram, its descendants, after a day of wild asexual abandon, will collectively weigh as much as a mountain...in two days, more than thesun - and before very long, everything in the universe will be made of bacteria." Not to worry, says Sagan: Some obstacle always impedes this kind of exponential growth. The bugs run out of food, or they poison each other, or they are shy about reproducing in public.
Carl Sagan 曾经开玩笑地解释这种现象,假设有一种细菌每15分钟可以分裂一次,亦即代表每一小时复制四次,一天可复制96次,虽然单一个细菌其重量只有一兆分之一公克重,但是只要经过一天无止尽的无性生殖,其重量可能会比一座山还重,经过两天后,甚至会比太阳还重,要不了多久所有的宇宙都将由这种细菌所组成,不过 Sagan 又说,大家不必担心,上天一定会安排障碍来阻止其倍数成长,有可能他会耗尽食物,或是毒死自己,或是有可能羞于在大庭广众之下复制。

After changing the export market into domestic market, the farmers change their way to manage their tea plantation as a small- scale peasant economy. These farmers only grow tea trees which for making Ching-shan Oolong, Jin- Xuan tea, Tsuei- Yu and Si Ji Chuen tea. Most of these plantations expand all over the hill side and rising ground in Taiwan by using asexual reproduction such as layering and cuttage. Especially the high mountain are as in Taichung, Chayi and Nantou. These places are the main areas growing Oolong Tea, and are famous for growing the high quality of half globosity Pouchong Tea.
台湾的茶叶在转为内销之后,茶园以小农各自独立经营为主,主要栽种适合制作乌龙茶的青心乌龙、金萱、翠玉及四季春等茶树品种,产区则从北部往中南部延伸,再往东部扩张,以无性生殖的压条或扦插为主要繁殖法,扩及到全省适合种茶的山坡地、丘陵地、台地,俗称乌龙茶的半球型包种茶遍布各地茶区并且以追求品质精良的高山乌龙茶为尚,台中、嘉义、南投的高山茶区,是高山乌龙茶的主要产区。
