If we burn all the fossil fuels we will doom the planet. We can't do that. At least not without carbon sequestration.
LOL that just shows your lack of intelligence, doom the planet, so does consuming oil mean the earth will plummet into the Sun ?? NO!!
In a million years time, the Earth will still be there, human race likely won't like 300years before going back to the dark ages anyway, it's the human race which is at risk not the planet.
Get the basics right!
