Humans would not be able too breath and probably die
The human body essentially relies on oxygen to keep its muscles functioning, if there was no oxygen then humans would first use the oxygen it already had in the bloodstream. The body would then turn to anerobic respiration to keep the body functioning. After that the body would probably fall into a coma and die from oxygen deprivation
Without the exchange of oxygen and carbon dioxide, humans would not be able to adequately supply their cells with oxygen for energy production and remove waste carbon dioxide from their bodies. This would lead to cellular dysfunction, organ failure, and eventually death.
If there were no plants, there would be no plants to take CO2 from the atmosphere and absorb the carbon and release the O2, which is oxygen. Which, would result in death because humans and animals depend on oxygen.
they will die
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 Patronum483 :)
There would be less genetic variation in humans
There would be no oxygen therefore no humans or animals.
Humans would die, because plants make our oxygen
There would be more CO2 then Oxygen. Humans would either adapt to it or slowly start dying.
Nothing would happen. Humans ARE animals.

If humans killed ALL plants on earth, we would all suffocate. This is because plants convert co2 (carbon dioxide), which is exhaled by all animals, back into oxygen through photosynthesis. If they didn't convert co2, the earth's oxygen supply would depleat and we would fill the atmosphere with co2, and we would have no oxygen.
we would all die
If all the plants die,there will be no oxygen.and without oxygen the humans cannot breathe without it.
Humans need to bring food, water, oxygen,
If there were no oxygen on Earth, most living organisms, including humans, would not be able to survive as oxygen is essential for respiration. Without oxygen, aerobic organisms would suffocate and eventually die. The atmosphere would likely become unbreathable, leading to widespread extinction of life.
Without oxygen, most living organisms, including humans, would not be able to survive. The process of respiration, which is essential for generating energy, relies on oxygen. Without it, there would be widespread death and extinction.
they would die.
