With rising food prices， growing population and environmental problems， many people are worrying about how we will feed ourselves in the future. Don’t worry. Scientists are trying to find some answers.
Some scientists believe insects will become a staple of our diet. Insects provide as many nutrients as ordinary meat and a great source of protein(蛋白质) ， they also cost less to raise than cows and use less water. About 1，400 species are suitable as food for humans. Many people have already eaten insects as a part of their diet. Locusts are popular in Africa， wasps are a dish in Japan， and crickets are eaten in Thailand. The Dutch government is preparing for insect farms and has invested one million euros into research.
In the future， land and fresh water will be in short supply. It is possible that people need to find a reliable food source in the ocean. Scientists have already found one at the bottom of the food chain---seaweed. It has long been a staple in Asia， and countries including Japan have huge seaweed farms. Such farms can easily work in other countries and be very successful. The great thing about seaweed is that it grows at an amazing rate. It’s the fastest growing plant on earth.
Scientists are also working in the lab to solve the problem of food shortage. A few years ago， European scientists successfully produced lab meat， also known as cultured meat. They grew muscle tissue using stem cells(干细胞)taken from cows. The experiment was funded by NASA to see if lab meat was a food astronauts could eat in space.
In 20 years’ time ， lab meat is likely to become a popular dish of our diet. According to research， growing meat in a lab rather than slaughtering(屠宰) animals can greatly reduce greenhouse gases， along with energy and water use. People can also reduce fat from the meat and add nutrients.

I don’t have too many memories of my father because he was so sick in the last years of his life. But there are some that I am often reminded of and which may have developed my love of science.
When I was small， I was somewhat afraid of lightning and thunder（雷）. My father explained it. The explanation was in words that a child could understand but was basically correct. I gained a better understanding and learnt something from him.
What he said was that there was electricity in the clouds and it traveled to the ground like a spark(火花). When it traveled through the air， it made the air so hot that it burned. Then there was nothing where the air had been and the air all around rushed in to fill the space. Saying this， he clapped his hands together very loudly， pretending to be the air rushing in， and said that makes the thunder. When I hear thunder， I can still hear that clap clearly.
He also explained why a cloudy winter night was warmer than a clear one. When there were clouds， they were like blankets(毛毯) which kept the earth and us warm. He said that if there were no clouds， we had no blankets and were exposed to the universe. Our warmth was going to heat the whole universe. Even today， I still feel on the edge of space on a very clear night.
I am sure there were many other lessons that I took but no longer remember most of them now. What I did learn， in general， was that there were explanations and that the more I understood them， the more comfortable the world was to live in. I was not taught that there were mysteries but that there was understanding if you looked for it. This may be why I have always taken an interest in science.

After giving a talk at a high school， I was asked to pay a visit to a special student. An illness had kept the boy home， but he had expressed an interest in meeting me. I was told it would mean a great deal to him， so I agreed.
During the nine-mile drive to his home， I found out something about Matthew. He
had muscular dystrophy (肌肉萎缩症). When he was born， the doctor told his parents that he would not live to five， and then they were told he would not make it to ten. Now he was thirteen. He wanted to meet me because I was a gold-medal power lifter， and I knew about overcoming obstacles and going for my dreams.
I spent over an hour talking to Matthew. Never once did he complain or ask， “Why me?” He spoke about winning and succeeding and going for his dreams. Obviously， he knew what he was talking about. He didn’t mention that his classmates had made fun of him because he was different. He just talked about his hopes for the future， and how one day he wanted to lift weights with me. When we had finished talking， I went to my briefcase and pulled out the first gold medal I had won and put it around his neck. I told him he was more of a winner and knew more about success and overcoming obstacles than I ever would. He looked at it for a moment， then took it off and handed it back to me. He said， “You are a champion. You earned that medal. Someday when I get to the Olympics and win my own medal， I will show it to you.”
Last summer I received a letter from Matthew’s parents telling me that Matthew had passed away. They wanted me to have a letter he had written to me a few days before:
Dear Dick，
My mum said I should send you a thank-you letter for the picture you sent me. I also want to let you know that the doctors tell me that I don’t have long to live any more， but I still smile as much as I can. I told you someday that I would go to the Olympics and win a gold medal， but I know now I will never get to do that. However， I know I’m a champion， and God knows that too. When I get to Heaven， God will give me my medal and when you get there， I will show it to you. Thank you for loving me.
Your friend，
Matthew
