The link between<span> oxygen and cancer</span> is clear. In fact, an underlying cause of cancer is usually low cellular oxygenation levels.
In newly formed cells, low levels of oxygen damage respiration enzymes so that the cells cannot produce energy using oxygen. These cells can then turn cancerous because they don't make enough energy to function normally in the body.
by protecting surviving rainforests means more oxygen available
