Imagine our world without oxygen. Oxygen is important because it's the reason why we are alive and living the world today. If it's not because of oxygen, we should not have been here today. Oxygen is the gas we breathe in and we all know that breathing is important; otherwise, we die. We, humans, need oxygen.
