What is the cleanest place on earth?

Answer 1

Comedian Michael McIntyre claims it's Montreal.

On a more serious note.

The cleanest place on Earth is the world's largest and highest-energy particle accelerator, the Large Hadron Collider (LHC).

Built by the European Organisation for Nuclear Research, this colossal collider took 10 years to complete and sits beneath the Franco-Swiss border near Geneva.

Answer 2

In one way the question makes no sense, because "clean" is an ill-defined term.

One candidate might be computer chip factories, since even slight contaminants can ruin very expensive chips. Another might be biosafety level 4 laboratories, which work with agents which are known to cause severe to fatal diseases in humans and for which vaccines and other treatments are not available.

Answer 3

The cleanest place on earth is often considered to be Antarctica due to its pristine and untouched environment with minimal human activity and pollution. The continent's extreme cold temperatures and isolated location help to maintain its cleanliness.
