Let's say they are 100% correct in this film...
If Al Gore is all wrong and CO2 has nothing to do with global warming etc, does that REALLY make polluting right? Does that REALLY mean we can use as much oil as possible?
If polluting doesn't affect global warming, that's great! However, that doesn't mean that polluting is harmless, and definitely not to be encouraged.
Oil is non-renewable, and very efficient. Oil will eventually run out, and we're not even close to replacing it.
Oil is used for food-production, electricity, and fuel for vehicles. Basically everything that makes life easy is possible because of oil.
If we invest in renewable sources for electricity etc, and reduce our dependence on oil, we will:
-Save oil for an (several) eventual future crisis.
-Not have to depend on unstable governments to access oil (Middle-east anyone?)
-Help the environment.
How's that negative? People will loose their jobs is the only possible negative aspect, but will they really? Replacing oil with new technology will generate a lot of jobs.
However, what if this film is wrong, and Al Gore is right?
-Millions of people will die
-Millions of people will have to relocate
-Millions of people will get a worse living-standard
-Oil will be harder to access, harder to transport, and will be desperately needed
-The future generations will never live in the luxury we in the west now experience
-We will cause damage to the earth and ecological systems that will take many many years to repair, it's even possible.
I think it's worthwhile to stop driving SUVs', drive with a catalysis, try to avoid oil-use as much as possible, use energy saving light bulbs etc.
Better safe than sorry I say.
