Tibetan Plateau ideal position for powerful observatory to bridge East-West divide

A Chinese study published in Nature suggests the Tibetan Plateau in China is ideal for building large telescopes due to its clear skies, stable weather, convenient infrastructure, and remote locations. The study highlights four main factors for site suitability and compares the potential projects with other large observatories worldwide.

Why is it important for the potential telescope locations to be remote and protected from human activity?

What comparison is made between the smaller telescope projects at the site and other large observatories around the world?
