The Problems of the Solutions

I've always had a strange interest in architecture a job that can go from being extremely boring to one of the most exiting jobs on the planet.
From now on I'll be making just some 2 minutes post to explain some various aspects of Modern Days Architecture
What some of you may now and some you don't is that in every single infrastructure (house,building,tower,nuclear plant etc) there at least one or more architect.
These days with the earth getting more and more over populated people will need more and more places to stay which is why this is a golden age for architects, they are the ones that have to find solutions and as we may or may not know solutions often bring new problems who themselves will have to later be solved and thats one of the main reasons a lot of clever projects are never even started, for example:

PROBLEM: The world is getting more and more overpopulated which means that around 10-20 years from now there won't be enough place for every one
SOLUTION: Cut trees in a forest like the amazon and build you house there
NEW PROBLEM: We need trees for living cause they make oxygen which is essential for humans therefor the law makes it illegal to cut trees in allot of areas.
NEW SOLUTION: Make some columns that go from the ground to up and build the house over the trees

NEW PROBLEM: Building a house like this is very expensive and if you build to many houses like this they'll  block the sun from reaching the trees which means the trees will die.

This is just one of millions of projects that didn't get realized because of this vicious cycle.
Well if you like this just dig this or stumble it, whatever do whatever you want, new post coming next week.
