Every one of us impacts the world around us everyday, and you scientists know that you can't actually -- even if you stay in bed all day, you're breathing oxygen and giving out CO2, and probably going to the loo, and things like that -- you're making a difference in the world.
每天我们中的每个人都在影响着世界， 在座的科学家们都知道，不可能有人对世界没有影响—— 即使你天天躺在床上，你也在吸入氧气 呼出二氧化碳，你也会去上厕所， 还有其他类似的事情。 每一个人都在影响着我们的世界。
