Travelling in todays society

Two questions put forward. Responses for a brainstorm for my article about work travel.

TRAVELLING IN TODAY’S SOCIETY

I intend to write a story on travel, in the first instance about work travel.
I wanted writer’s responses to two debates I will now put forward.

The two debates are:
1. How far should people travel to work for the interest of environmental sustainability?
2. How do travelling long distances affect the mind at work?

I am just after initial reactions and thoughts, which would enable me to create a brainstorm for my work.
Any responses greatly appreciated.
