Why plants are green.

The Permian-Triassic extinction event's hydrogen-sulfide-tinted green skies shaded out all non-green photosynthetic life.

       Are you implying that the Permian-Triassic extinction event's hydrogen-sulfide-tinted green skies shaded out all non-green photosynthetic life?   

       Also, how would this work, given that H2S is colourless?

       What shade of green ? Can you give a Pantone number ?

       Perhaps the green colour is camouflage, so they can't be easily seen in the jungle.

       Why would green light favour green-coloured plants? Surely it would favour plants with leaves which absorb, rather than reflect, green wavelengths?

       Soooo... where's the evidence of "non-green photosynthetic life" ? There is non red/blue-absorbing bacteria. But they're still around.

       .....and the idea is????????

       There are also plenty of red photosynthesizers.

       Well, copper beech trees anyway.

       I'm calling it. [marked-for-deletion] Reason? Devoid of an idea, and also total bollox.

       Maybe [brian]'s idea was to set up his keyboard so a single key would write out "The Permian-Triassic extinction event's hydrogen-sulfide-tinted green skies shaded out all non-green photosynthetic life." That could be a great time-saver.

       All photosynthesis articles say stuff like "oxygenating type of photosynthesis", with the very obvious conspiracy-theory inducing unsaid "there's other types as well".   

       Turns out there is. Also turns out that nobody gives a shit about them, because those articles are equally sketchy.

       What do you mean? Have you never read ‘Top Secret?’

       //And my best friend is dead//   

       Not sure how seriously to take that.   

       I mean, we could be looking at a dog, a missing testicle, a real honest-to-goodness bout of PTSD or just a rather tasteless po- mo stream-of -consciousness text generator bot. Because we haven't known you very long it's hard to be sure.

       Just copy from the original & paste into your own comment. There's no clever trickery that does it for you auto-magically.

Welcome back, by the way.

       Late Latin adjective - "stubborn". For the historical character, see Google. There is no evidence that he was murdered for stubbornly correcting the grammar of his own bodyguards, but I can imagine it that way if I like.
