I think the two are related and when we decide to take better care of the planet we will take better care of each other and as long as we continue fighting and destroying each other we'll do the same to the planet. I don't think they are related. But if we all had that same opinion, it wouldn't necessarily make it correct. The planet will survive us. By millennia. Your ideas about world dietary change are mis-placed, but noble. It is true that meat production is a waste of arable land, and the world would have more food if we stopped farming livestock, but it has negligible effect on methane production, which has been reported by Vegans etc. More methane is released from the oceans than cattle. But that is due to cyclical climate change, nothing to do with cows and sheep. Like I said previously, whatever we do will change nothing. The planet will do what is does. It might get too warm to sustain life as we know it, or we might have volcanic activity and begin a mini ice-age. Or worse still, a super-volcano, such as the Yellowstone Park one may erupt and wipe out all life form. You eating nuts won't change any of that. Don't lose sleep over it though. None of that will matter if the paranoid left are right about Trump.

Supported Palace for over 69 years since the age of 7 and have seen all the ups and downs and will probably see many more ups and downs before I go up to the big football club in the sky. |

If I had to bet I'd say the earth will be here long after humans but hopefully I'm wrong, who knows. Extinction events seem to occur about every 30 million years, which coincides with the frequency of the Solar System's passage through the orbital plane of the galaxy. The theory goes that the increased quantity of matter close to the orbital plane disrupts the Oort cloud causing increases in the numbers of comets coming into the inner Solar System and thus an increase in the risk of collisions with comets (and asteroids). The last such event took place at the end of the Eocene about 34 million years ago and is thought to be associated with a 100km-diameter crater in Siberia. The one before that was the end-Cretatceous impact 65 million years ago to which you refer. A comet struck Jupiter in 1994 (this is far more common than comets striking the inner planets, and Jupiter's gravity protects the inner planets from incoming comets to some degree). The most dangerous object in the Solar System at the moment is Comet Swift-Tuttle. It will pass within 15 million miles of Earh in 2126 and again in 2261; it will pass within 3 million miles in 4479, with a chance in a millon of a strike; and if it strikes it will do so with 27 times the energy of the end-Cretaceous event credited with rendering the dinosaurs extinct. That's all based on current predictions of the orbit which become less and less certain the further out you look.

It's speculation, not fact. The same with planetary warming. All the scientists have to go on is guesswork and probability. You may as well flip a coin as to if or when a comet will, or more likely won't strike this planet. None of us, or the scientists, appreciate how big the solar system is, let alone the effects of other solar systems on ours. You can track celestial objects over any amount of time, but no scientist, or computer, can predict what will happen. Only what might happen. If we worried about what might happen, we wouldn't be discussing this, as we wouldn't have evolved.

OK, I apologise to Rikz, who makes some salient points. It was rude and wrong of me to abuse. attached is a graph (I don't have time to look for a better one) The last spike (unfortunately the years aren't put on the graph) begins around the time of the Industrial Revolution (1760-1820). Coincidentally, this is the time humans started burning oil, gas and coal (fossil fuels), which produce CO2 as a by-product. Anthropogenic activity is theorised as being the cause for this rapid rise in temperature. You will note 2 things.
To that end , Rikz nay have a point , in that the current temperature rise may be unstoppable. I would argue that humans should at least try to minimise the damage that they have contributed to. For moral, financial and practical reasons. Our political cycle (5 years) has contributed to our short-term planning

And yet we also had the Tungusta Event in 1908, which wasn't properly investigated for another 20 years.

Maybe consider banning football. Judging by this website there appears to be a lot of anger and hatred amongst Palace fans, let alone the opposition.

It's difficult to take your participation seriously when you decide a debate on whether someone has made a mistake while quoting. You don't need to listen to me anyway like I said all the information is easily accessible. They are all theories, opinions and predictions(plenty have been proven false). We have such a insignificant affect on mother nature that I wouldn't even worry. It's probably not a bad thing for the world's economy that a market has been created due to global warming and it's not a bad thing that people are more aware of trying to preserve our planet as best we can but if you think for one second we have any serious say on the earth's climate then you are wrong. Edited by rikz (22 Jan 2017 2.03pm) Touche' I apologise.....my concerns about our planet is not so much global warming, but the way we are destroying animals habitats and killing them unnecessarily for ivory etc and other trophies as well as bogus chinese health remedies. I agree that in the main our planet's warmth cycles are pretty much immune to our interference.

whatever damage, we as the human race, are doing will harm us alot quicker than the planet. Once we are out of the way, the planet will regain control and settle itself back down again.
