转基因作物商业化种植的发展速度较大， 1992年只有一个国家种植，到1996年增加到 6个，1999年为12个2003年为18个。1996年种植面积为170万hm²，1999年为1210万 hm²，2003年增加到6770万hm²。其中，美国、阿根廷、加拿大、巴西、中国和南非等国家的种植面积占全世界种植面积的99%。在转基因作物中，以大豆的种植面积最大，占58%；其次是玉米，占23%；棉花占12%，油菜占6%。其转基因性状，以耐除草剂为主，其次为抗虫性。在1996-2000年的五年间，耐除草剂转基因作物的种植面积占74%，抗虫性转基因作物的种植面积占19%。据国际农业生物技术应用机构统计，2003年全世界种植转基因作物的农民已有700万，比2002年又增加 100万。

我国的转基因研究始于20世纪80年代初，80年代中期生物技术已列人国家的“863”计划。1998年我国开始推广转基因抗虫棉，当年推广24万hm²，到2003年达到307万hm²，已占棉花种植面积60%，且国产转基因抗虫棉品种逐步占主导地位，到2004年已占近 7%。其他作物，比如水稻、小麦、玉米、油菜、花生、大豆等方面转基因技术的研究，在我国全面展开。

My wife passed away seven and a half years ago, and I went through a huge depression (消沉), the worst time in my life. I even wanted to end my life. I continued to work as a small-town doctor at my medical clinic in Kilauea, Hawaii. My kids had gone to live on the mainland, and I was alone. On a family trip, we turned on the TV and saw the second plane crash into the World Trade Center. I said to my kids, “I’m going to Afghanistan.” International Medical Corps sent me to set up 20 clinics in some provinces where people had no health care. Eventually, the clinics were serving 27,000 patients a month. I had such a sense of accomplishment, a sense of purpose. My depression went completely away.

I go wherever disasters strike: Indonesia after the tsunami, Pakistan after the earthquake. I was just in Kenya. After their presidential election, at least a thousand people were killed and hundreds of thousands were forced out. We set up mobile clinics in an area with 19,000 refugees (难民). Measles broke out, one of the biggest killers of kids in refugee camps, and it spread like wildfire. Water and medical equipment were also problems.

When my wife passed away, I thought my life was done. But really, it was just getting started. At the end of her life, my wife fell into a coma (昏迷). I held her head in my hands and told her of all the places we would visit, the exciting adventures we would have. I think about this moment many times during my “adventures”. I did not know then how prophetic (先知的) those words would be. She is with me still.
