Still Waters Posted March 3, 2021 #1 Share Posted March 3, 2021 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. https://theconversation.com/a-billion-years-from-now-a-lack-of-oxygen-will-wipe-out-life-on-earth-156241 4 Link to comment Share on other sites More sharing options...
thedutchiedutch Posted March 3, 2021 #2 Share Posted March 3, 2021 (edited) Not overly concerned yet lol. A lot can happen in around 2 billion years from now Edited March 3, 2021 by thedutchiedutch Link to comment Share on other sites More sharing options...
+Nuclear Wessel Posted March 3, 2021 #3 Share Posted March 3, 2021 Technology that will exist at that point will prevent that from happening. Link to comment Share on other sites More sharing options...

If we ever successfully master space travel, I doubt we'll even need too. Link to comment Share on other sites More sharing options...
