And we are beggining to form an estimate of the world's condition that is in
some ways even more disturbing than the environmental bad news of twenty or thirty
years ago.Now we know that human activities alter the biosphere and affect
the evolutinary future of non-human forms of life everywhere.
Deserts,forests,fields,and rivers have been changed.
Some species of plant and animal life have disappeared, and others have
been created through selective breeding.
Even the atmosphere , the oceans , and the climate are not what they once
were.
In this greatly modified and humanized world, there is no longer any real distinction
between "natural" and "unnatural."
Even our most well-intentioned activities , such as maintaining green areas
and protecting endangered species , require active help in the form
of law enforcement and scientific management.
