A billion years from now, a lack of oxygen will wipe out life on Earth

A lack of Oxygen will wipe out life on earth.  This will happen.  We’ve put it in here for educational reasons.  Its a long way away.  Humans will be long extinct anyway.  Some of the science in here is ammunition for the deniers of man made climate change.  Please think with your head and not your heart.  Extract below:

Earth will not be able to support and sustain life forever. Our oxygen-rich atmosphere may only last another billion years, according to a new study in Nature Geoscience.

As our Sun ages, it is becoming more luminous, meaning that in the future Earth will receive more solar energy. This increased energy will affect the surface of the planet, speeding up the weathering of silicate rocks such as basalt and granite. When these rocks weather the greenhouse gas carbon dioxide is pulled out of the atmosphere and through chemical reactions locked in carbonate minerals. In theory, the Earth should start to cool down as carbon dioxide levels fall, but in around 2 billion years this effect will be negated by the ever-harshening glare of the Sun.
