Okay, good,look in nature.. when a population reaches its limit ( that is in resources ) most will die.. and the few left feed the new growth. its a cycle.. as you said... but....our case its pretty extreme tho.. land will be shrinking... it depends on how fast the polar ice caps melt.. and if/when the population rises and falls we will be rebuilding from scratch again.. and by the time we get into the state we are in now again we may have evolved? .. therefore not really human..

being a geek isnt a disadvantage, its a blessing.
