Відповідь до p. 165 ex. 7:

Reducing CO2 emissions is perhaps the world's biggest problem. If we don’t reduce our emissions to almost zero, global temperatures will continue to rise. At the current rate, temperatures will have increased by three or four degrees by 2050. CO2 emissions are about to come down if one of three things happens. First, if we change our lifestyles and stop using electricity; second, if the gadgets we use don't need energy; or third, if we find a way to generate electricity without producing CO2. Well, people are not going to stop using electricity. If anything, in 30 years' time, they will be using more. Perhaps in the future, gadgets will be consuming 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 have generated our electricity in 2050? No one knows, but the miracle will need to happen soon.
