I think that one day insects wuill inherit the earth. I have just been watching a David Attenborough documentary about African ants. These ants are farmers. They take grass back to their mounds and a special fungus is grown on it. It's the only place in the world that this fungus grows and these ants eat it. However, it produces dangerous carbon monoxide so the ants have built their mounds to have air conditioning so that harmful fumes are got rid of. It's amazing. Individually the ants have no intelligence, but collectively they are like cells in a massive brain.

Blimey - so ants are contributing to global warming?

Noooooo LM they aren't.

Y-es. It is also a naturally occuring substance and has been around for a very long time.


*thinks probably as long as LM's guests have been wondering where she is*

Blimey Mr. H - that post (almost) sobered me up...beautiful.

LM the earth's atmosphere is a greenhouse atmosphere and always has been. We breath in Oxygen and breathe out CO2, plants abosorb it and release oxygen and so on. The issue is the over prduction of CO2 above and beyond the normal balance of life on the planet and in that regard we are mostly responsible.

No it hasn't. Earth's atmosphere has changed throughout the history of the planet. For example, there was much less oxygen in the atmosphere 2400 million years ago. Oh and there are far less rare gases in the atmosphere now than existed a very long time ago too.


PS. *warns moles to leave LM's cider alone*

I'd like to know what you consider to be the 'modern lifespan of the planet'. The trouble is.....this often varies from person to person. Makes it very difficult to accurately demonstrate scientific facts. So your earlier comment about the Earth's atmosphere having always being a greenhouse environment is completely inaccurate, to put it politely.


When do you think the 'greenhouse atmosphere that gave us the ecosystems we have' came into existence?


The planet used to have a reducing environment and then it became an oxidising environment.

No those greenhouse gasses are what have allowed the earth to have the range of temperatures necessary for life. Without them too cold, too much of them too hot. It's called the 'Goldilocks Principle' and is why we are the only planet on our solar system with life. The main gases are water vapor, carbon dioxide, methane, and nitrous oxide and they trap sufficent solar energy to create the right temperature ranges.

    • Whilst I agree, I have been thinking about this recently in relation to some of the other posts on here about anti social behaviour. We are all products of our upbringing - our experiences at home, school and beyond - plus whatever we have inherited genetically which might affect our behaviour (the nature/nurture thing). So in this case, if people haven't been brought up to love and appreciate trees and other wild things, plus as you say they may be deeply unhappy (or have other undiagnosed issues) it's easy to see how they could have ended up doing this. Also, it's possible they had quite low intelligence and didn't really grasp what they were doing and the effect it would have on so many other people. But that's just surmise and possibly completely wrong. From what I've read about it, they seemed to be two mates egging each other on, like two big kids. I'm not for a minute excusing what they did, and it's right they should be punished, but I really hope they might get some sort of rehabilitation in prison (it would  be appropriate to have them do some kind of community service like planting saplings, wouldn't it, or working in woodland conservation). And the same goes for phone robbers and shoplifters (rehabilitation, not planting saplings), though for SOME  shoplifters there might also be other issues at play, not excluding poverty. Sorry Jasonlondon,  I've gone off at a real tangent here, lucky it's in the lounge! Oh oops I've just noticed it isn't. Sorry admin. Oh, and then there's a whole philosophical discussion to be had about free will and determinism ..... 🤣🤣🤣
    • Thanks! I'll find out in a few weeks when I get the results! It was one of those disconcerting things where a disembodied voice keeps booming  at you to breathe in and hold it, then breathe normally. Apart from that it was OK, all completely painless.

    • Two men behind ‘senseless’ felling of Sycamore Gap tree jailed for more than four years Good to see these two jailed today for four years. There’s something deeply disturbing about people who destroy trees—any tree. Whether it’s a centuries-old landmark or a sapling in a quiet park, trees are living beings that offer beauty, shade, and life. The men who cut down the Sycamore Gap tree are a stark example of how far some people will go to lash out at something peaceful and meaningful. People who harm nature like this aren’t just destructive—they are often deeply unhappy. It takes a troubled mind to look at a tree and see something to ruin instead of something to protect.
