There's so much pollution in the air now that if it weren't for our lungs there'd be no place to put it all. Задания: как вы понимаете это высказывание ... 5-7 предложений

It is the sarcasm. There is a lot of pollution in the air and it covers all the planet. We created this pollution by ourselves. So we need to consume it now with our lungs. Our lungs became a big garbage bucket. And a lot of dirty air circulates through our lungs. And here we have the sarcasm, that we save the Earth by consuming all the pollution by our lungs, but we forget that we, people, created all these. If we care more about the environment, there would not be any air pollution.
