According to the official version (even if you do not take into account the inconsistency of
radiocarbon dating ):
Thanks to the tiny air bubbles frozen in amber 80 million years ago, you can get data on the Earth’s
atmosphere in the era of dinosaurs. Studies show that at that time in the earth's atmosphere
contained twice as much oxygen as it is now. So, it was 42 percent. Over time, the oxygen content
decreased, and the study of air bubbles in amber from the Cretaceous period shows that the oxygen
content then reached 32 percent. Link
2. Once the Earth’s air consisted of 38% oxygen and 1% carbon dioxide (this shows the study of air
bubbles in amber). Today, due to environmental pollution and other factors, oxygen in our air is only
19%. Link
3. The oxygen content in the Earth’s atmosphere is steadily decreasing. Millions of years ago it was
about 40% (according to the analysis of amber air bubbles), by the beginning of the 20th century -
24%, now - does not exceed 20% (although 20.8% is considered). In the atmosphere of megacities of
oxygen no more than 15%, and in industrial areas of large cities its concentration often approaches
the dangerous line for humans in 8 - 9%. Link
4. Scientists determined the gas composition in air bubbles, which are often found in amber - the
petrified resin of ancient trees ¬, and measured the pressure in them. The oxygen content in the
bubble turned out to be equal to 28% (while in the modern atmosphere at the surface of the earth -
