Do we truly KNOW what we are doing?

Of course we don't. Often we act with the best intentions, but the results are disastrous. Think back to DDT - it was going to revolutionize agriculture, increase crops, prevent world hunger. Instead it turned out to be a poison, with horrible, unpremeditated effects. Mankind keeps doing things like that - somehow we think that we can overturn something what has taken millions of years to evolve and change a universe that is in tune with itself, and then we are shocked and astonished when it doesn't turn out the way we thought it would.

I haven't viewed the film - sorry, but 30 minutes is a little long to sit at the computer. But this is my thought on your original question.

Friend, don't waste your days caring about these scum societys of the 21st century. Let nature take its course. The earth will take its revenge against us before we manage too destroy it. Godbless

Nope, because its a bottomless chain reaction.

Let me ask you another question:

Would we be where we are today if we didn't know what we were doing?

No, dawg
