If there are good arguments against oil use, they don't come from scarcity. Just as technological improvements make alternative energy sources more capable, they also allow access to oil reserves that had either been unreachable or economically infeasible to utilize in the past.To put it in perspective, the Athabasca Oil Sands alone have been estimated to hold two trillion barrels worth of oil, the vast majority of which cannot currently be collected. The entire world's current proven reserves are 1.3 trillion barrels.Scarcity isn't an issue, and it becomes even less of an issue as time passes.

Did I say scarcity was the only issue? It's simply one of many - as I said, it has "numerous and fundamentally damaging flaws." I'm sure you're aware of most of them, though, so I won't rattle them off.
And even in regards to the apparent untruth of the scarcity of oil... regardless of how much exists, we are consuming it far, far more quickly than it is produced by natural processes, and we will run out some day - so we need to be investing in alternatives. We are aware that it is finite. We are aware it will run out. We are aware we will need an alternative. We are aware that to replace the amount of energy we currently get from fossil fuels, a lot of research and development is needed to find alternate sources. The logical step is pretty obvious: start researching and developing alternatives. I'm not saying everyone should convert to electric cars now, or that we should switch entirely to solar energy, because those technologies aren't ready yet. Which is kinda my point: they aren't ready, they need to be ready, so we need to invest in them.
So both due to scarcity - because, really, regardless of how many trillions of barrels we have left to extract from the bowels of the earth, it is undeniably finite compared to renewable (and thus, for all [i]practical[/i] purposes, infinite) energy sources - and due to the multiple other issues with fossil fuel use - pollution, the risk of spills, and so on and so forth - I believe there needs to be investment in alternative sources of fuel.

You have disposable income. Buy some shares in an alternative energy mutual fund.

Actually, I don't. I'm saving for university. But honestly, what's your point here? Some oft-trotted out argument about me needing to take action to back up my words? Please, spare me. The question was about Keystone XL and whether we feel government should allow it to go forward - and, therefore, what I said was in regards to government action, i.e. government investment and legislation.
