With the world’ s population estimated to grow from six to nine billion by 2050, researchers, businesses and governments are already dealing with the impact this increase will have on everything from food and water to infrastructure (基础设施) and jobs. Underlying all this 【C1】______ will be the demand for energy, which is expected to double over the next 40 years.
