"The task of showing whether or not
humanity is viable rests with us - each of us. Unlike
other species, humanity can anticipate the future, make
conscious choices and deliberately change its own destiny.
For the first time in the whole history of evolution,
responsibility for the continued unfolding of evolution
has been placed on the evolutionary material itself. We
are no longer passive witnesses to the process, but can
actively shape the future. Whether we like it or not, we
are now the custodians of the evolutionary process on
Earth. Within our own hands lies the evolutionary future
of this planet."
