As far as I'm concerned it's government policy - specifically Planning Guidelines.HOw are you all on the Driving issue?? versus public transport/cycling? Orr id that more an effect of govt policy than individual choice?
The GAII theory talks of a self regulating earth.But surely ,as fossil fuels begin to run out/get very expensive the effects of fossil fuels on the environment will go into reverse,along with our standard of living.....talk of self regulating!!!
what`s this about the black sea?
I AGREE it is govs or rather lots of govs incl all the big boys acting in concert that is needed to make a difference. But the individual is only concerned about his/her immeadiate future.....and the politician must concentrate their energies on winning the next election....what would the voting public do if cowen said he was going to keep our billions surplus for our grandchildren?
Yes,there is a great danger that as oil and gas run out, countries will use up all their coal and other dirty fuels ,causing enormous pollution globally.
If you study (and believe) what Scientists are saying at the moment the polar ice caps are already melting. For instance, the ice caps themselves started to melt from the top. But...many years back it was believed it would take a long time for a whole ice cap to melt. The reality is that warmer, melted water actually seeps down to the bottom of the ice...dislodging it and moving the ice out to warmer waters...thus accelerating the melting process. The flooding, and other weather changes are already happening (again if you believe the science).Actually, China want to use coal because they have vast coal mines...not for any other reason.
As I said...depending on your perspective mankind is putting a great deal of effort presently into finding alternative fuel sources. It's highly unlikely that we'll run out of oil and then turn around and say..."What's next?".
I understand that there are still sceptics...but again...ask yourself why there is so much movement towards these technologies and why governments around the world are beginning to take emissions so seriously. It's certainly not driven by people...a lot of people are still quite ignorant of the implications of climate change....dwindling rain forests and dead seas.

Well i think its looking HIGHLY LIKELY , that as oil/gas becomes scarcer and hence the price becomes prohibitively expensive....people will be saying...what next?
Are you suggesting that mankind will effortlessly move from oil/gas to an alternative energy seamlessly.
CHINA OF course will use up its coal reserves causing chaos.......the fact that it has like many countries huge reserves of coal makes that inevitable......but china could buy a lot of coal from other countries if it had to.
Firstly, all remaining energy is likely to be super expensive,and secondly there will be no viable transportation fuel available...a fuel that has net energy output and doesn`t use up too much desperately needed agricultural land.
What has gaii got to do with it...the invisible regulating hand may turn out not to be so benevolent...just whaacking and flailling around blindly.
AND THE BLACK SEA?

I think there are great limitations to technology.
No doubt nuclear power plants will be built ..the technology for that already is used.
however hydrogen fuel cells use a lot of energy to make the hydrogen...where is this energy going to come from?
The reality is they will be hydrogen and electrtic powered cars but the cars and the energy will be so expensive,that only the very rich can afford them.
MY understanding of the gaii theory is that it seeks to portray the earth as a self regulating body....this is just wishful thinking...if like the black sea ..gets polluted..species die....thats just a sequence of events.
Don't you mean the consequences for humanity were this not to happen? The consequences for the planet itself would be better served if we weren't around.Do you understand the consequences for the planet were this not to happen.
Perhaps, if it were not so highly inefficient to do so which is why almost all hydrogen produced today is derived from natural gas thus resulting in more energy being used to generate the hydrogen than the hydrogen itself releases.Water actually....believe it or not.
It may be a fact that the ability to produce cost-effective hydrogen fuel cells would lead to the mass production of electric cars but until cost-effective hydrogen fuel cells are viable the merits of the electric car over the internal-combustion powered car are still debatable. Even if/when the cost-effective hydrogen fuel cells is mass-producible we are still left with the problem of how to generate all the electric power that is required. Thus the whole hydrogen/nuclear debate ensues.Incorrect...GE have already built concept cars...and shown them...based on a chassis that is significantly cheaper to mass produce than modern cars. No petrol engine...no need. No clutch etc. As I said...it's fact that once the abiity to mass produce hydrogen fuel cells is achievable we'll all be driving them.
What? The faith in technology to save us from ourselves? Thus far the increases in technology have mainly allowed us to grow at an unsustainable rate and consume the finite resources of the Earth in an ever increasing acceleration.I have great faith in technology...nanotechnology...biotechnology...these will play significant roles in the next 20-30 years and provide huge breakthroughs.
