Saudi city 2

(cont'd from yesterday's post)

Doubters point out what they see as weaknesses in the idea for this new city ("Is That A Good Idea?").

One expert says planned cities are often unsuccessful, and suggests that some aspects of The Line should be tried in existing cities. He wonders if people will like being confined to this space surrounded by a desert.

Another doubts that the environment will be better off. He says the carbon cost of this huge construction would overwhelm all the environmental benefits.

Others think The Line will require such enormous control of variables that it may not be possible, even in an autocratic society like Saudi Arabia.
