If you eat meat and believe in global warming you are a hypocrit.

That's my point, we have brains, yeast do not.

It's pointless to have a brain if we don't use it to look at (and plan for) long-term sustainability.

The price of oil goes up because of demand, global short-run supply/production capacity has gone up and has not gone down. Long term, it will start to drop at some point.

Unfortunately, in this case "long term" is not very long according to an increasing number of studies. Here's the latest from the IEA (which by the way seems sugar coated at some points):

"Capacity additions from current projects tail off after 2010," the Paris-based agency said. "This largely reflects the upstream development cycle: Many new projects will undoubtedly be sanctioned in the near term as oil companies complete existing projects and move on to new ones. But the gap now evident between what is currently being built and what will be needed to keep pace with demand is set to widen sharply after 2010."

Tanaka said that "while market imbalances will feed instability, the era of cheap oil is over."

(...)

However, Tanaka said it was "far from certain" those companies would be willing to make the necessary investment themselves or to attract sufficient capital to keep up the necessary pace of investment."

If the population goes too high, people will die. The population hasn't started declining, so we must not have reached that point.

There's a bit of a fallacy in that thinking. Resource depletion happens no matter the population level, no fixed limit needs to be reached in order for problems to happen. Sustainability means having a good plan for long-term sustainability, and executing it on time. Unfortunately I'm afraid it will become increasingly obvious that we didn't do enough fast enough.
