We look at where the emissions are coming from -- they're coming out of our tailpipes and smokestacks and so forth, and we say, okay, well the problem is that they're coming out of fossil fuels that we're burning, so therefore, the answer must be to replace those fossil fuels with clean sources of energy.
我们看到排放气体的来源-- 它们来自我们的排气管和烟囱等等 然后我们说，恩，问题就是 它们来自化石燃料的燃烧 因此，解决方法一定就是 把那些化石燃料换成清洁能源
