I guess this film is supposed to depress me...
but at the end the narrator lady is 75 and earths population is 2.8 billion. She lives in a small community as the new 'dark age' comes and the human race has dwindled...
but know what? I look forward to that.
Look, overpopulation is the elephant in the room in the global warming/climate change 'debate' -- countries refusing to adress their own out of control growth as farmland is over cultivated into dead soil, water is used up, etc. So the world presented at the end is a handful of cities as enclaves of wealth while the worlds population declines to 'only' 2.8 Billion from disease, starvation etc. Mean while, folk figure out that places like New York City, Miami (New Orleans) just aren't sustainable because-- gasp -- coastlines change!
With less of a population, this means less people chasing after water and tearing down forests...even if you don't believe in global warming, the idea of less people fighting over water and food means the world should be back in an equilibrium.
And I love that one guy "It'll take earth 100000 years to recover from the damage we've done" -- no it won't, hell maybe not even 100 years and the earth will keep right on chugging along. Society might be altered, but that'll be up to future generations to worry about the face of society. One thing I can be sure of : no one will worry about 'carbon credits' or 'ecological footprints' when we are small communities surrounded by thick forests.
