A. In the next few weeks the government will launch a new educational program to attract attention to green issues. People will have to change their lifestyles if they want the world's resources to support the growing population in the coming years. Reducing CO2 emissions is perhaps the world's biggest problem. CO2 emissions will come down if we will change our lifestyles and stop using electricity; if the gadgets we use won't need energy; or if we will find a way to generate electricity without producing CO2. Well, people won't stop using electricity. If anything in 30 years' time, they will use more. Perhaps in the future, gadgets will consume less energy, but certainly not zero energy. That leaves only one possibility. Scientists will have to find a way to generate CO2-free electricity. Wind and solar power are only intermittent energy sources. What miracle invention will be designed by 2050? What will generate our electricity in 2050? No one knows, but the miracle will happen soon.
