There is a serious problem related to global warming is that in British Columbia there is a scourge of our pine trees occurring in our dry Interior of what is called a pine beetle. Since it doesn't get below about -30 degrees centigrade for 3 weeks anymore in the winter, these pests do not get killed in the winter so for probably at least 15-20 years now they have gone on the rampage and killed large swaths of our pine forests.
When the sawmills in BC saw this pine beetle-killed lumber it is so dry it creates a lot of fine dust in the mills. Due to poor control of this dust there has been two explosions in which this dust has ignited and 2 or 3 workers have been killed as a result. So in this way global warming can be deadly to human activity if extra precautions are not taken.
Carbohydrates are the sugar, starches, and fibers found in vegetables, grains, fruits, and milk products. They are the most important source of energy for your body.
The Vatican archives stores multiple precious documents and books of the world. These old documents dating hundred of years are kept in high nitrogen levels, in order to prevent the oxidation of the paper (papyrus). The presence of the high level of inert nitrogen in the air in the archives prevents any kind of damage that may caused to the paper or the ink on those documents. This high level of nitrogen, however, may affect the health of the individual by decreasing the oxygen levels in the body.
Hence, the answer is 'the oxygen level will be decreased in the body'.
The best answer is genetics
