I didn't want to bring up depopulation. It's too real and too depressing. 300 to 1 my bet is on a pneumovirus. Something like the never before or after seen 1918 Spanish Flu.

Nature abhors but nevertheless cures excesses. Automatically and ruthlessly.

China is right in the X-ring for the next pandemic.

Simply crippling the pharmaceutical chain would depopulate the US by eighty million.

Invest in a retirement property will crops will grow and convert your RV into a crewed turret. A MORTAR MOTORHOME anyone?

Now you see why I avoided this.

David ... as clarification, in no way am I a fan of what the dark side of "depopulation" may mean. What I think we need is a much smaller Earth population going forward through enforced birth control on a world scale ... starting as soon as possible. ;)

In the meantime while the above is taking affect over time - we need a full court press on solar farms, wind farms, ocean wave farms, energy storage reservoirs, natural hydro-electric plants, much more buried grid wiring, better vehicle battery technologies, and if ever possible ... the Holy Grail of earth-bound nuclear fusion.

Total "Bovine Stuff".

The earth's people population would take much less space than you think..

HERE is a good explanation..

"If we stood side by side, about 3 feet apart, 7 billion people would form a line 21 billion feet apart. This is about a 4 million miles long. The distance to the Moon is about 240,000 miles, so we’d go way past the Moon.

Let’s put everyone into a square giving each per a square yard of space. The population is over 7 billion, so we’d need 7 billion square yards which is under 7000 square miles. So we’d all fit into a square that was less than 100 miles by 100 miles. This is about one-fifth of the area of Maine.

Estimates are that there are 15 billion acres on the Earth that are habitable. So there is about 2 acres of land per person."

Now I know that does not address all of the sky is falling "green advocates" concerns about greenhouse gasses killing the earth..

Those are also recycled total Bovine stuff..

The earth is self cleaning and self recycling, we do not and cannot "add" to what there is not.. Neither can we "take away" stuff from the earth.

WE as humans ARE made up of CARBON, we NEED CARBON to live, OUR BODIES USE CARBON in order to live.

Plants USE CARBON to flourish, without they would DIE, plants like trees, flowers, grass take in carbon, they DEPEND on carbon IN THE AIR, without is they would no longer be. Scrub all of the carbon out of the air and not only will the plants die, WE will die to..

Yes, their is carbon "sequestered" deep inside the earth, but if we (us humans) do not release some of that carbon (natural gas and oil), the EARTH WILL EVENTUALLY RELEASE IT as part of it's own natural cycles (earth quakes, volcanos and even natural oil tar pits and so on).

I am not saying that we should go nuts with waste of natural resources, we should use it wisely to our advantage but that we do not have to be overbearing to the point of not "multiplying human population"..

Take a good hard look at China, they have for many years have had forced population limits even down to taking unborn lives.. It didn't work, it will never work.

Nor do we or should be so gosh darn worried about forcing supposed "green" ways of life on people, in most ways the green ways are not so green if you start really breaking down the real science behind it, studying all of potentially harmful processes and chemicals involved in making those supposed "green" ways (not the hyped science by the likes of Gore and friends).

Do some research on what it takes just to make a solar CELL, it is a very similar processes to making any semiconductor. Uses a lot of highly toxic materials, chemicals and energy and creates more left over hazardous waste than what you started out with..

Man only flatters himself to believe that he can make or destroy this Earth..

Wow, talk about a whole lot of Bovine Stuff.

Hmmm .... where does the Bovine come from - MEXICOWANDERER, or pnichols, or Gdetrailer, or two of the three, or all three? ;)

Here's some comments:

1. So ... is the CO2 up there at high levels or not? If levels are indeed high, then the greenhouse effect is going to increase. Of course experts can measure the levels - and their data shows that they're high. Hence weather is going to get more and more screwed up. Does it matter where the high levels of CO2 came from ... well yes -> if it came from fossil fuels and you're portfolio depends upon them continuing to be used.

2. How many people can get squeezed together on the Earth is a strange angle to come from for justification of "bring em' on -> the more people consuming and throwing away stuff the better". Watch "Soylent Green" if you think humans living squeezed together all over the world would be OK!

3. Chinese population control through control of births was an early attempt on their part ... good for them to at least try it. However, it needs to be done with a lot of fining tuning well beyond how the Chinese tried it - and it needs to be done on a world scale. Holding the world's population at some wisely and benignly determined self-sustaining level will insure our future generations can continue to live in a wonderful environment that remains that way until the sun becomes a red giant.

4. Man can indeed "destroy the Earth". Study what happened in Europe and the "real reasons" they found it necessary to find new places on the planet to expand into and get resources from. Now imagine the whole Earth eventually getting to the point Europe was at but with no place for the whole Earth to expand into and get resources from (science fiction space movies notwithstanding).

5. It's a pipe dream that 15/20/30/etc. billion future people on the Earth could live as many people in the U.S. and other developed nations live today. It would take several Earths for that to be possible.
