我把高产改成解决粮食危机的法宝了,就是因为预料到你会那么说。如果高产的背后是高价的种子专利费,你认为高产还能解决粮食危机吗?更何况转基因还未必=高产。
这是中国大力发展转基因技术的原因, 不用问别人买。 以中国现在的国际地位, 钱不是大问题, 三寸被人捏着才是大问题。
可以说人生的美好在于未来的不可预测,但恐怕不能说世间的美好在于未来的不可预测。因为人类科学研究的有限而导致的未能预测到的世间惨剧不少,美好不起来。要想少一些惨剧就必须对大自然、对无限的未知世界保持应有的敬畏和审慎,而不是狂妄地以为掌握了某些科学手段就可以对自然界为所欲为。
这是我们俩人的区别。你看的是人生, 我看的是宇宙。如果我对自然没有敬畏, 会反对三峡大坝么。
随便搜了两篇关于转基因和粮食危机的文章,不代表我的全部观点,为兼听则明起见,供有兴趣的人参考。

Does GM technology increase yield?
GM crops were not initially designed to increase yields.
It's a simple question... but the answer is more complex.
It depends how you measure yield. The GM crops we have at the moment were designed to help farmers manage insect pests and weeds. By reducing the amount of crop farmers lose to pests, GM means they have more to harvest.
But these GM crops were not designed to make plants grow bigger, or grow more intensively, so in this sense they do not increase yield – nor would we expect them to.
