根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。Science fiction television has done a lot to shape how we view the meals of the future, from an evening dinner in pill form to machines giving us any meal we desire, on demand. However, while these ideas for food creation are more than fifty years old, the way we produce and consume food has not changed very much. Even though there is enough food available today to feed the world, more than 870 million people do not have enough to eat. With the global population expected to grow to more than nine billion by 2050, demand for food will only increase. No pills or machines have solved our food problems yet.However, agricultural science has been responsible for saving huge numbers of lives. Science and technology helped us out of starvation during the 1960s and 70s when the world's population exploded. The result of this panic was the "green revolution", which saw the introduction to farming of high production grains, improved irrigation systems and hybrid(杂交) seeds, saving over one billion people from starvation. Having enough food is only the first step. There are complications with natural disasters, conflict, poverty and environmental problems. All these can mean that the food supply is put at risk. Many people are concerned about "playing around with nature", adjusting how food looks and tastes and smells, and other human interferences(干预), all of which are widespread.Anyhow, the world has not been completely saved from starvation, but we are on the way to get there.A. Agricultural science was quite a success.B. There are many complexities when dealing with food.C. Modern science and technology of food contributes a lot.D. Nobody would ever starve if food were this easy to obtain.E. And it is unbelievable that hunger kills more people than disease does. F. Then there are the issues we face when it comes to food experimentation. G. At that time scientists were worried that we would run out of food.
