I have moved some posts from the Environmental issues-thread to their own thread.
The topic at hand has become the nuclear threat, and other armageddon like threats to our whole existance, how real are they and what can be done about them.
I will leave all the original posts in spoilers and copy the parts that are relevant for this new topic to be fully visible.
With mod-greetings,

I doubt we will be destroyed over the environmental issues however as the growing threat of world wide nuclear war is advancing faster than the decline of the environment.

Yes plastics can be made from non-petrol sources just like houses can be powered by solar energy, but most of the time they are not. What is cheap usually wins out.

In fact, the original form of plastics was/is made using cellulose (obtained primarily from cotton) and a derivative of camphor (from laurel trees). There is no petrochemical dependency for the production of plastics, it's just presently cheaper (stick a hole in the ground, and out churns decades of profit).
The most important element in the production of solar panels is silicon, the 8th most abundant element, by mass, so that's not an issue either. Solar panels can be, and are, produced using little to no petrochemical products.
The big issue with wind and hydro power is "moving parts," which requires far greater maintenance. Seriously, moving parts are far more likely to break than stationary parts and far more likely to have a catastrophic breakdown (cascading collapse). That's the real reason why solar energy is a better alternative. I mean, wind will (for all practical purposes) always be there, as will running water. The perpetual nature of these three sources of energy (four, if you wish to include geothermal in this discussion) is not in dispute, it's the harnessing of such in an affordable and cost-effective manner.
We have become dependent, spoiled if you will, upon the "cheap" of petrochemicals. As I indicated above, all it requires is one month of drilling a hole to obtain 20 years in profits. But, it's not a perpetual resource and is estimated to last maybe another 50 years before depletion. Now, that doesn't mean there won't be anymore petrochemicals (an important note to point out, particularly considering Willypete's misinformed assertions), it will simply no longer be cost-effective.
So, really, the race for alternative energy isn't because we'll be out of petroleum, it's because eventually it will be too expensive; the increasing costs to extricate and process will force the price up substantially, which will make all other dependencies also rise in costs (petroleum used in shipping, packaging, transportation, etc).
The need to resort to alternatives, the drive to research more efficient means to harness such perpetual energies as wind, water, geothermal, and solar, is not a political ploy, it's a practical reality, an economic necessity. Our societies are built on an assumption of "cheap" fuel. Now we're in a pinch to maintain those societies "as is" or face the daunting task of fundamental, and culturally shattering, societal simplification (back to the basics).
