Now people in growing numbers are enjoying the benefits at dinner table from the application of the new scientific advances to agriculture.
現在，越來越多的人從餐桌上就能感受到新科技應用到農業方面所帶來的好處。

They appreciatively attribute what they eat every day, from different kinds of new vegetables to new fish varieties, to the efforts of scientists.
人們總是對科學家的工作充滿感激，因為是他們的努力才使得自己能吃到各種各樣的新品種蔬菜或是新的魚類。

However, can further scientific advance help the world solve the problem of future food supplies?
但是，人類是否能進一步借助科技進步來解決世界未來的糧食供應問題呢？

Some people stand to it that the advance in science will keep staying ahead of the food crisis of the world and provide a needed relief for the future supplies.
有些人堅信，科技進步將會始終超前于糧食危機而發展，并為未來的糧食供應提供必要的技術支持。

They base their belief on such ground as science has effected the tripling of food yields since the green revolution of the 1960s and 1970s.
其中他們提出的依據之一就是：科技進步已使世界的糧食產量，相對于60年代和70年代綠色革命時期增加了3倍。

Accordingly, they believe that more money for agricultural research can lead to another green revolution. Will their expectation come true?
據此，他們相信，給農業科研投入更多的資金必然會出現另一次“綠色革命”。他們的這種希望會實現嗎？

In fact, the rapid population growth and environmental pollution are changing the basis of agricultural resources for the use of new technologies.
實際上，人口的快速增長以及環境污染正在改變著技術應用所需要的農業資源。

According to a recent report, for example, the spreading cry for protein is straining limited agriculture land and draining tight fresh water supplies around the world.
比如，根據最近的一份報告，世界對蛋白質急劇增加的需求，已使有限的耕地資源變得貧瘠，加劇了淡水資源的短缺。

If man’s attention is only put on the potential of scientific achievements, the earth’s limited economic resources will give up along with the increasing mouths to feed.
如果人類的注意力仍然只放在技術開發上，那么，地球上有限的資源將無法再供養不斷增多的人口。

As is pointed out in the report, future food supplies will depend as much on family planners as on fishermen and farmers.
正如那份報告所指出的，未來的糧食供給既取決于農業耕作者，又取決于計劃生育的決策者。

I think that the reduction in population growth and the protection of resources and environment take the same responsibility for feeding the world as any big scientific advance does.
我認為，在保障人類糧食供給方面，采取措施降低人口出生率，保護土地資源和環境，將與任何重大科技成果一樣，有著同等重要的作用。
