what is the current oxygen level in the air(india)??????????? 10pts!!!!!!!!!!!!!?

The oxygen level is the same everywhere - approximately 21%. In India and everywhere else in the world.

Photosynthesis releases oxygen into the atmosphere, while respiration and decay remove it from the atmosphere.

So my suggestion is just plant more trees.

Don't worry about the oxygen level decreasing. Yes, the level IS a tiny bit lower than what it used to be in PREHISTORIC times when the dinosaurs were still running around.

It used to be as high as 35% once and this led to the large size of insects and amphibians in the Carboniferous period.

Since the beginning of the Cambrian era, O2 levels have fluctuated between 15% and 30% of atmospheric volume.

Whilst human activities, such as the burning of fossil fuels, have a vast impact on carbon dioxide concentrations, their impact on oxygen levels is less significant

So in short, we will have plenty of oxygen for ourselves and many generations to come :)

EDIT:

AS I HAVE SAID PREVIOUSLY, THE OXYGEN LEVEL IN THE WORLD IS APPROXIMATELY 21%. LOL.

Oxygen Level In Air

The current global level of oxygen is at 21%. HOWEVER, industrialised nations, industrialised areas have a much lower oxygen level, some areas are as low as 15% and quite a few are at 19%. Historical data (as measured through different means too complex to expose here) have shown that at the end of the dinosaur era, it was at 33-35%; it dropped considerably immediately after as the forests burned. During the Pleistocene it was back up to 28%. Then us HUMANS discovered fire, and well, we began cutting the oxygen production by burning trees; at the beginning of the industrial age it was at 25%, 200 years later, you have what you have due to deforestation, coal, oil and natural gas burns + the destruction of the plankton in the oceans. Expect to need breathing apparatuses in 200 years; we as a species cannot evolve fast enough to breath at 13% oxygen. You don't believe it? Look at statistics: asthma, emphysema are exploding. Tumours are also exploding and are well-know to be associated with lack of oxygen (partial combustion leaves way too many free ions that destroy vital biological structure). Ah yes, we are growing dumber: the brain requires oxygen to function and grow. It's not CO2 that will kill us, it will be lack of oxygen.

definitely in urban India, contamination levels in oxygen have increased because of deforestation and establishment of industries.

am not sure with data and stuffs ,. but oxygen doesn't have country boundaries , its same all around the world

20.9% at sea level, but goes down as altitude goes up. It's been 20.9 for a long long time, ever since humans have been around.

if we grow less trees and plants and make more cars and bike it will decrease every where.

23.3

23.3% iam damn sure about that......
