Are GM（转基因的) foods safe for people? Can they help solve the poverty problem? They have been the subjects of a hot debate.

This debate is related to increasing challenges from rising climatic change, population growth, urbanization（城镇化), and natural resource consumption. According to the Food and Agriculture Organization, food production needs to increase by 60 percent by 2050 in order to feed 9 billion people. Scientists and policymakers are searching for effective ways to gain nutritious food, for today and future. Unlike previous agricultural methods (such as the Green Revolution), GM crops are to fight food safety and poverty challenges.

The great expansion of GM crop varieties over the last two decades can be seen easily. The total area devoted to GM crops has increased 100 times from 1.7 million hectares in 1996 to 170 million hectares in 2012. Developing countries now grow more GM crops than developed countries (in terms of area), largely driven by Brazil’s rapid adoption of GM crops. China is home to about 4 percent of the total global area devoted to GM crops. Beans, corn, and cotton are main global GM crops, while China’s focus is on cotton, papaya, and poplar.

Recently, a scientific study shows that GM crops are safe for people and the environment. According to a 2010 report on the safety of GM crops by the EU, “the main conclusion to be drawn from the efforts of more than 130 research projects, covering a period of more than 25 years of research, and involving more than 500 research groups, is that biology methods, are not more risky than traditional planting technologies, for example.” Other international and national scientific bodies, such as the World Health Organization, have reached the same conclusion.

It’s exciting to imagine how future humans will have solved the problems we have now, or what amazing new inventions will make our lives more convenient and interesting. We asked top scientists to share their predictions on what the world will be like in a century. If they’re right, the 2114 is going to be really cool.

1. Robots will do your chores and more

Robots will be doing most of our jobs, from building homes to teaching math. There are already robots that clean floors and pump gas. In the future they will be more complicated and useful. Unfortunately, with robots taking all the jobs, unemployment will be high.

2. You will read minds.

Speaking of being social, we will communicate in an entirely different way. Forget texts and emails. Mind-reading technology will allow us to send thoughts to each other without speaking a word. We will also be able to send thoughts to objects around us. (Instead of pressing “start” on the microwave, you could just think “start.”) Meanwhile, chips implanted（植入in our brains will improve memory and intelligence.

3. Your car will drive you

Today, around 30,000 Americans die in car accidents each year. One hundred years form now, accidents will be a thing of the past. According to Mark Safford, consultant or the U.S. Department of Transportation, future cars will drive themselves. These electric cars will communicate with other cars on the road to travel safely in close formation at high speeds.

4. You will eat fake meat.

Raising animals is not an efficient way to produce food, and it harms the environment: Cows, chickens, and pigs eat a lot, and then we have to deal with all that poop（粪便. What’s more, that poop can up poisoning lakes, rivers, and streams. Today, scientists can “grow” meat in a lab from animal cells, but it’s expensive and not very delicious. In the future, they will have perfected the process. You’ll order hamburgers that come from factories, not cows. Scientists may even find ways to make lab-grown meat tastier and healthier than the real thing.

1.According to the passage, what is likely to happen when robots become more common in the future?

A. People will be much lazier.

C. People may become physically weaker.
