So there can be no oxigenrich atmosfere on waterworlds without life! Remember; the dino toppled over cause the phytoplancton vanished! No oxigen, no dino! (Phytoplancton only lives in cold water...... Good thing we got a canary. Our mighty whales! When they are all gone we should have a thought or two about looking into the matter.... Old mining tricks are OP!) *This is about applying RL science into gameworlds like Nemo etc. This is less about fud :wink:
