How Can The Earth Become A Lifeless Rock In Just 150 Years As The Movie Depicts?

[PunkMaister]

In the movie the level of environmental damage is beyond insane to say the least. Needless to say not even the worst of the worst of supercomputer models places the planet in such dire circumstances just 150 years from now, so how does it get to that point in the first place? Just how does Earth gets to a level that rivals the permian extinction in which 99.9 of all life on Earth perished?

In Avatar's Earth life only exists in 2 forms Humans and Algae and not green algae either as there is no sunlight to photosynthesize anymore but a genetically engineered Chemosynthesic variety.

There are 2 schools of thought one that believes that a combination of very damaging wars, and both natural and man-made disasters of unimaginable scale wrecked the Earth.

Then there those that say that just population and greed does that kind of damage in 150 years time. Well hello Dolly hold the presses. We have been in an industrialized society for over 200 years now, if things got damaged at the rate we see in the movie we would already be wearing Exopacks to breathe in the streets right now. Damage like cause over just the use of resources would not turn the Earth bare and lifeless in 150 years it would take centuries for the atmosphere to become like in the movie unless the following things happened. And keep in mind that unlike the movie we are moving toward renewable resources and so on.

A. Starting from this date all humans became insane in the membrane and cut down all the trees in the planet, killed all it's domestic animals not for food but because they wanted em dead.

B. Humanity deliberately massively for no good reason poisons and nukes the oceans so no living creature is left alive. does any of this makes sense? It probably does to those that propose this school of thought whatever...

C. Humanity burns not uses just burns Saddam Hussein style all the oil, coal and fossil fuels the world over. Then it also burns down all it's cities and whatever woodland and grassland that might be left. Again does this makes sense? Apparently it does...


All of the above done continually for years or a decade etc might turn the planet into the toxic lifeless soup we see in just a 150 years time as in the movie.

This is just to illustrate that the timeline for that kind of damage is just way off the charts. Having said that we still need to take care of our planet but if anyone thinks we could be in that same situation 150 years from now this is the only 2 ways that could happen. Again which one makes the most sense to you...
