How your lungs refine oxygen from other gases?
Your lungs refine oxygen from the other gases in air because the gases diffuse through the cell walls in the alveoli in your lungs through osmosis (higher concentration of gases in the air than in the blood, so gases move from the higher concentration to the lower concentration) where they contact the red blood cells. The hemoglobin in the red blood cells binds to the oxygen and leaves all the other gases alone. It moves on from the lungs and delivers the oxygen to the rest of the body. It's the hemoglobin that does the work.

Are there possibilites of changing greenhouse gases?
Greenhouse gasses or GHGs (carbon dioxide, methane and a few others) are emitted from natural and manmade sources. The Earth is set to handle the amount from natural sources, but the extra from manmade sources tips the balance to cause a slow increase in the GHGs. Mankind can restore the balance by * reducing the emissions from fuel burning (the primary cause) or * by increasing the amount taken from the air by increasing forest cover or the creation of other carbon absorbing systems.
