Again, not really the time to get all controvercial in a game like this... so...
Also I am a man of SCIENCE. There is always a way to solve a problem. It may be minutes from now or it may be months or years from now, but there is always a solution.
What the government needs to do is offer incentives for this. The U.K. already has a plan for this in effect in where it's cheaper to buy an electric car than a gasoline (or petrol) car. All in all it's not impossible to save ourselves.
Honestly, it's not that much of a doomsday scenario. While it is a bad situation (and it is BAD indeed) it's not impossible to stop it. If everyone used a car that was a couple of gallons more efficient than their last one, we would cut back on our CO2 production by quite a bit.
This is the result of not replanting saplings in mine craft ecks dee
But +1! This saves still looks good, nonetheless. :)
I personally believe that the world will end because of mans' evil, but not in any way you would think. I believe in God, and that, very soon, in the blink of an eye, most of the human race would've sadly ended up in hell. This is why this is no time to get all controvercial in a game like this. It's not made for it. (Seriously, read the rules.)
That is mainly because the process of 03 being broken down by a CFC is way too long to cause this much catastrophe in 70 years or less.
A mere 70 years of CFC's are nothing compared to tens of thousands of years worth of volcanic eruptions that, had they have occured today, would've sent of right back to the stone age. The chemicals inside of those eruptions are far more dense and potent than the ones we've ever released. In fact, what we've done has barely even left a dent in the atmoshpere that is 11 - 40km thick, mind you.
That same population will plummet as soon as the Earth starts biting back. Any extinction to a species of animal caused by the natural world (whether or not you believe in a meteor or flood) killed off the species because it was too invaluable to Earth itself. If you think the planet heating up because of stuff we've been doing here, I wouldn't stop laughing. Billions of years before our very existence carbon levels in the atmosphere were five times that of today.
