Humans need oxygen to survive and think.If you dont have enoff oxygen for your brain it will stop working and you will eventually die.Humans also need oxygen sso that they can breath out carbon dioxide.If we didnt have oxygen we wouldnt have carbon dioxide.Carbon Dioxide is the thing that plants breath in.So if we didnt have oxygen plants would die.And then the animals that eat plants will die.Then the animals that eaet does animals will die.And we are omnivore(means we eat plants and animals)so if there were no plants and animals we will die of hunger
That is why we need oxygen
