The biosphere is the thin living skin of the Earth — the places where animals, plants, and tiny living things can actually live. That is soil, forests, rivers, the surface of the sea, and the lower air, not the dead rock deep below or the empty space far above.

It is a science-class and environment-news word, not something you say when you mean “outside.” Though actually people stretch it, and say “our biosphere” as if it simply meant “the environment” or “the planet.” The tidy idea is more precise: it is the living layer, where rock, water, and air meet life.

It is a science-class and environment-news word這是科學課和環境新聞裡用的詞 not something you say when you mean 'outside.'不是你想說「外面」的時候會用的字。Though actually people stretch it不過其實人們把它延伸了 and say 'our biosphere' as if it simply meant 'the environment' or 'the planet.'會說「我們的biosphere」，好像它就是「環境」或「地球」的意思。The tidy idea is more precise比較嚴謹的想法其實更精確 it is the living layer, where rock, water, and air meet life它是那個生命所在的層次，是岩石、水和空氣與生命相遇的地方。
