„Human activities are a quasi-geological

force.“

IASS Institute for Advanced Sustainability Studies – Prof. Dr. Klaus Töpfer 7

“Mankind will remain a major environmental force for many millennia.

A daunting task lies ahead for scientists and engineers to guide society towards environmentally

sustainable management during the era of the Anthropocene.

This will require appropriate human behaviour at all scales, and may well involve internationally

accepted, large-scale geo-engineering projects, for instance to ‘optimize’ climate.”
