Evolution. I think you're on the money. You may be interested in perusing paleontologist, Dewey McLean's hypothesis on the impacts of CO2 on biodiversity.

His hypothesis, although presented in 1994, on mass extinctions, is interesting where he suggests that the emissions of CO2 and greenhouse gases, from volcanic eruptions, sparked the extinctions millions of years ago.

I do believe his hypothesis was worthy of more attention.

Rehctub, I'm not sure if you want everyone to agree with you, or you actually want to hear "SOME REAL FACTS?"

Nevertheless, uranium mining does in fact use a massive amount of water. U mining does in fact use a massive amount of energy.

Olympic Dam in SA are the largest private users of energy in the state. If we resorted to nuclear power to solve our problems, this would mean that some states in Australia would see large areas of land mass dug up to extract uranium, releasing large amounts of CO2 and of course the resulting problems of the release of radioactive waste and its monitoring for perpetuity, all adding to the pollution which is now out of control.

In addition, when the land uranium runs out, we would then resort to mining ocean uranium - our last surviving ecosystem. This is already an ecosystem which is seriously threatened.

Currently there are some 200 ocean dead zones which are so polluted, that fish cannot live there. Thousands of sea and shore birds around the planet are dying - the "canaries in the coal mine?" We are now resorting to desalinating sea water to supply major cities and beyond, with unknown ecological consequences particularly if many more nations adopt this practice.

And how long would it take to construct the 25 nuclear plants recommended which will do little to reduce emissions of CO2 but simply increase them. These are just a few concerns for starters.

There are several ways that anthropogenic CO2 could be mitigated. Unfortunately, successive state and federal governments are having none of that!

Dickie "There are several ways that anthropogenic CO2 could be mitigated."

Such as?

Dickie, rehctub here. I thank you for your information however I see little difference between digging up coal or uranium.

As for the water,(now there's another topic in it's self) I can't believe we are resorting to de-sal plants when we are already catching millions of litres it's just that rather than re-direct this water to our dams we choose to dump it into the rivers and oceans.

As for nuclear power costing more, I take your word for this as I don't know enough about it.

Another power sourse suggested was wind power. Not what we know today as this involved huge turbines being teathered at 10,000 feet to catch the high winds at that level.

Has anyone heard or followed this one?

As for the extincion theory, some years ago a theory was put up that dinosoures bread themselv'es out due to climate change, casued by the mediorite dust storm rather than dieing from CO2 poisoning.

Reserchers found through the farming of crocodiles, outside of their normal region, that the off-spring were born either all males or all females depending on the location of the farm. This was due to the change in the climate. Tropic/non-tropic or hot/cold as such.

We all know the mediorite struck and it is thought that the dust storm that followed had such an effect on the atmisphere/climate that the dinosores where born all the same sex and therefore bread them selv'es out.

Has anyone heard or followed this one?

The earth's history, in each event, is true. Some by volcanoes, and really! I don't want to type out all variables when it comes to extinction's.

But none the less, the Co2 is a killer! And I think its fair to say, we are slowly snuffing ourselves out. Yes it will take a long time, but what if, the levels just happens to co-inside with the worlds next great shift. No-one knows what going to happen next, but I think with the evidence available, and its also fair to say, that we are just at the beginning of a new cycle, and unfortunately, and apparently, we are well over due for it. Generally, there are the here and now people and there's the, I think of the future people.

The now people are chewing this planet alive cause they know its not going to affected them in their short pointless lives. selfish isn't.

All the best. and thank you.

Hi VK3AUU.

1. Shipping: Crucially, shipping exploits a ready supply of the world's cheapest, most polluting "bunker" fuel. Marine heavy fuel oil, which is burned by all large ships, is the residue of the world's oil refineries.

"Bunker fuel is just waste oil, basically what is left over after all the cleaner fuels have been extracted from crude oil. It's tar, the same as asphalt. It's the cheapest and dirtiest fuel in the world," said Christian Eyde Moller, chief executive officer of the Rotterdam-based DK Group, a leading shipping technology company.

The world's burgeoning shipping fleet (about 90,000 large ships)currently emits 1.21 billion tonnes of CO2 a year. Why is this industry escaping the attention of governments? In addition, why do Australian governments permit the ocean dumping of dead and diseased animals from its ships of live exports (some 43,000 last year). Why does the industry refer to this as a mere one percent? Why is it prudent to continue to dump million of tonnes of animal faeces and urine, on a single voyage, into international waters?

2. Biodiversity: Again I harp on the millions of sheep, cattle and other cloven hooved animals bred annually for export. No more is that more evident that the state of the environment in WA which is in big trouble though is it just me who has any concern over the maniacal endeavours of governments here who continue to encourage growth in the export of live animals and every other damn thing?

3. Motor vehicles emit the largest source of CO in Australia (2.2 billion in the last NPI report). CO converts to CO2 once burnt. Air pollution is blighting the lives of millions of people where those who drive bumper-to-bumper daily in the sea of chaos, are inhaling petrol and diesel fumes beyond their capacity to remain immune to these contaminants.

Governments have a duty to implement best practice in pursuit of high standards to reduce emissions. Those who continue to drive the most polluting vehicles should incur additional taxes to those already implemented.

4. Population increases? Suicidal!

Hehe, so shipping, by far the most efficient method of transport,
is the problem.

Plus of course 40'000 sheep, how could we forget them?

Never mind the tens of billions of fish, crapping in the ocean
every day. Never mind the many passengers liners, dumping their
waste in the oceans. Never mind the sewerage of billions of
people, being discharged into the ocean.

Get rid of shipping and 40'000 sheep and you will change
the world! :)

Time for another cup of tea for our Dickie, to calm her nerves :)
