True, GM foods are already very much a part of our lives (已成为我们 生活的一部分), and farmers have a strong incentive to (迫切地想要) use the biotechnology as it can raise overall crop productivity (能提高稻谷 产量), yet we need a deep philosophical discussion of its implication. We still remember that when pesticides were first introduced, they also were praised as absolutely safe and as a miracle cure for farmers. But for all that promise (尽管这么多保证), decades later the technology revealed its truer lethal implications. Hence, any technology should be subjected to rigorous testing (应该进行严格的测试) before its wide application.
In developing countries, lost crops are only one cause of hunger. Poverty plays the largest role.
