 Democracy Now, a relatively smaller station, did present such concerns of the international community.

 Xi called for firm determination and great courage in phasing out industries and companies with high levels of pollution and emissions, which reserves space for the development of new industries.

 搞转基因土豆的当然不止孟山都。1996年,巴斯夫向欧盟申请了一个叫做Amflora的转基因品种。土豆的主要成分是淀粉,包括直链淀粉和支链淀粉两类分子结构。支链淀粉可以溶解于水中,大大增加粘度,在制造生物聚合物方面很有价值。而直链淀粉不溶于水,对于形成生物聚合物会帮倒忙。对于吃土豆来说,其中的哪种淀粉多点少点也没多大关系,但对于加工而言,单纯的支链淀粉就要优越得多。而这个Amflora,是通过调控土豆本身的基因,抑制它生成直链淀粉,从而得到了“支链淀粉土豆”。这对于工业加工而言,自然就很有吸引力。巴斯夫的申请只是用于工业产品和动物饲料,并非用于食品。不过,也经过了十几年的等待,直到2010年才获得了种植许可。

 但在物价飞涨,稿酬还在原地踏步或者蜗牛式前进的当下,除了像郭敬明、韩寒等少数人气作家外,大部分作家已变成低收入人群,有的甚至还要自费发表文章和出书。而在网络载体海量存在的今天,发表作品已经不是作家的专利,作家的神秘感也已丧失殆尽。
