It may be possible for humans to live longer and need less oxygen at some time in the future, but it is not possible at this time. A human requires a certain amount of oxygen to maintain cellular function and although lifespan varies, most humans (even those who are long-lived) do not live past the age of about 90.
Extending human lifespan and reducing oxygen requirements are areas of ongoing research. Some studies suggest that caloric restriction, exercise, and certain medications may help increase lifespan and improve oxygen efficiency. However, significant advancements are needed in the fields of gerontology and biomedicine before these goals can be reliably achieved.
People who live in high altitudes (where there is less oxygen available) have more red blood cells to carry oxygen than people who live in lower altitudes (where there is more oxygen available), so their blood is thicker.
its depend where you live and what kind of food do you eat there do you get oxygen more or less
If the pressure of oxygen is less than 159 torr then it is considered low oxygen level. What is 159 torr in percentage of saturation?
Bacteria will evolve faster than humans .It is because it has less number of cells and less no. of genes .
There would be less genetic variation in humans
YES as humans we need oxygen to breath
Due to the destruction of the rainforests, there is less oxygen for humans to breathe.
Trees produce oxygen. If the tree is cut down, it will no longer produce the oxygen that the ecosystem needs. So when we cut down trees, less oxygen is being produced, and the less oxygen produced, the more uneven the balance of pollution and oxygen.
Shorter because you have less oxygen circulating your body
they breath out oxygen for the humans and breath in carbon dioxide which helps the earth have less carbon dioxide
Oxygen is less dense.
Your body only uses 1/4 of oxygen inhaled. Longer in your lungs means more oxygen used, less energy consumed.
A candle burns longer in the open because it has access to more oxygen, which helps to fuel the combustion process. In a glass jar, the oxygen supply may be limited, causing the flame to burn less efficiently and extinguish sooner.
One with less than 500 litres!
Depends on the species. Humans 9-10 months. Cats&dogs - a lot less. Elephants - a lot longer.
Deforistaion is people cutting down plant life, and making it even less likely foer humans to survive. It is obious people will die from no oxygen.
With life support, perhaps. Mars is much colder than Earth, has much less atmospheric pressure, and very little oxygen.
