现代社会正为全球变暖感到忧虑,部分原因是我们向大气中排放了过多的二氧化碳。但是,如果氧气取代二氧化碳增加,会发生什么?现在,地球大气中的氧气含量在21%到25%之间浮动。哪怕氧气含量只增加5个百分点,都可能造成严重后果。自然火灾和超级大树氧气是燃料

Now the oxygen content of Earth's atmosphere fluctuates between 21% and 25%. Even a 5% increase in oxygen levels can have serious consequences. Natural fire and super big tree oxygen is fuel
