O2 as a percentage of the atmosphere has declined by around half, according to the paleontological record, since dinosaurs roamed the earth?

And with that decline, more than doubled the pathogens now creating havoc in the world, Aids, Ebola and what have you? Oxygen being implicit in all cures or abundant good health!

Interestingly, some almost non curable external ulcers can be successfully treated in an oxygen rich environment in a compression chamber?

And to date, the only available remedy for diabetic ulcers?

Given the gradual disappearance of water and or arable land, food shortages will continue to magnify?

There's mounting evidence for reincarnated? We will reap what we sow, or inherit a world and circumstances of our own creation; and absolute and perfect Justice!?

Evidence?

What about a( widely reported) young man involved in a serious motor vehicle accident and thrust into a coma for several years; and never once in this life ever exposed to anything Chinese! Wakes from the coma speaking perfect fluent Mandarin, clearly the most complex and most difficult language to learn on earth!

So, given all the hard evidence establishes he didn't learn his Mandarin in this lifetime, which previous lifetime did he learn it in?

And there are myriad similar case studies, where the only thing that support memories of a previous life, can only be explained by actual reincarnation? Read, life after life.

Something I acquired in paperback decades ago and with enough conclusive evidence to at least suspend credulity!

And doable for anyone except those with locked and bolted mindsets, or just refuse to accept that it could/might be so?

You know, the way the flat earthers refused to accept a round earth or evidence! And if the deniers are represented by three wise monkeys?

Then surely the accompanying caption should read; see no evidence, hear no evidence and repeat no evidence? No matter how compulsive or conclusive?

Verily verily I say unto you, to reach unto the Kingdom of heaven ye must be born again. Quote unquote.

Why has US wheat production stayed relatively flat? It shares the same atmosphere as India. Just wonderin'.

//Of course the sceptics have long argued that carbon dioxide is a plant food//

As has anybody else with an understanding of high school biology. That trees 'eat' carbon is an entirely uncontentious point. And there is ample evidence that increasing atmospheric CO2 concentration will have a beneficial effect on plant growth.

//The next time you get in your car, don't feel guilty about increasing the level of CO2 in the atmosphere, instead feel good inside about helping the Indian farmers grow more wheat.//

And the next time you see a cane toad, don't spray them with Dettol, instead feel good about them controlling cane beetles. Because if something has a an upside, you should focus on that to the exclusion of all the downsides. Some might regard this as suicidally stupid optimism, but others prefer to think of it as 'emotional intelligence'

Thinkabit,

Good, constructive comment. What a pity others don't do the same instead of continually repeating their fact-free, unsupported beliefs.

"Over the past several decades, through technological innovation, Americans now grow more food on less acres, eat more sources of meat that are less land-intrusive, and used water more efficiently so that water use is lower than in 1970. The result: lands that were once used for farms and logging operations are now returning as forests and grasslands, along with wildlife, such as the return of humpback whales off the shores of New York City (pictured above). " http://thebreakthrough.org/index.php/journal/issue-5/the-return-of-nature
It contains some interesting charts, such as US crop productivity and reduction in land needed for food production as population and GDP have increased.

Yes Peter, but think, the Sahara was once the granary of the Roman empire! And relatively nearby Lebanon was once covered in ceder forests!

And when Northern Ethiopia was covered in verdant forest, there was no lack of the rain that once supported hand to mouth agriculture!

And reafforestation in Kenya has made growing coffee for export economic once again!

Easter Island was once covered in trees and palms, and the Mayan civilization once lived in a rain forest that is now mostly desert unable to support much let alone a civilization!

And the changes needed to avoid following these cause and effect examples, can only ever improve our economic prospects!

Like carbon free thorium based energy connected to micro grids, that then halves the cost of industrial energy! And there's patently a vested interest posting against just that!?

So instead of bleeding industrial processes and manufacturing to the emerging economies, we reverse that process and our future prospects; and who's against that!?

And what harm could possibly ensue if we decided to convert our wasted waste to carbon neutral energy that reduced the average power bill by 75%; that then flowed on to an endlessly sustainable oil industry and complete self sufficiency in all energy products!

Only ultra greedy myopically focused vested interest, bleeding a captive energy market white, could possibly object to any of that, and the massive upswing in discretionary spending that would promote!

And if we would just accept the reap as you sow message inherent in the Christian bible, how many would continue to fowl their own nest, and or leave it to successive generations to fix! If it's still fixable by then?

It's not so long ago that the men of learning and letters believed/taught that we lived on a 6,000 old flat earth in the centre of a universe that revolved around it; and like all denialists; before and since, completely rejected any evidence to the contrary out of hand, no matter how compelling!

Rhosty: The examples you give don't support your claims. Here are some statistics for you-

Approximate current populations of:
- Lebanon : 5.9 million,
- Ethiopia : 96.6 million,
- Easter Island : 6150,
- the area of the Maya civilization includes all of modern day Guatemala and Belize, south-eastern Mexico and western Honduras and western El Salvador. Just Guatemala and Belize alone has 15 million, while the number of people current living in the whole area is considerably greater than this.

These figures demonstrate that these these regions now support many, many times the population than hundreds of years ago. To give you some scale, educated estimates of the whole world's population at 1000AD put it at about 300 million.

More importantly, on average the people living in these regions have a higher stand of living than those living hundreds of years ago. Yes, this even includes Ethiopia! (And it should be said that most of Ethiopia's current issues stem from ethno-social-religious problems and not from environmental destruction or failing land production yields).

As a separate point. You keep ranting on about Thorium reactors. Well here's the problem with what you claim: under a capitalist system, people will constantly search for and utilise the cheapest energy source since this lowers the cost of production and thus increases profits. Since thorium reactors are not used it demonstrates that they are not the panacea that you claim. (Of course some countries have a thing about nuclear power, but many don't. Note that, those that do allow nuclear power have not switched their electricity supply to thorium). Across the world coal is by far the most used source of energy which indicates that for the vast majority of cases it is the cheapest. There is no global conspiracy to not use coal nor to investigate/allow other sources. It is just that coal is the cheapest. Yep, it is that simple!
