The downturn is something people here read about in the newspapers, according to Dhanna Singh, a member of the Mazdoor Kisan Shakti Sangathan (MKSS), a union of activists and farmers.

根据德哈那.辛格，一分子与农场主联合会MKSS成员的说法，经济低迷只是这里的人们从报纸读到的谈资而已。

I do not focus on the Limits to Growth world model because I want to pick on its potent political implications (the first version did, after all, inspire a generation of antigrowth activists).

之所以把焦点放在“增长的限”这个模型，不是想对它的那些强有力的政治内涵做什么挑剔（毕竟，它的第一个版本给予了整整一代反增长的社会活动分子以灵感）。
