A three billion year old planet floating in the vast universe with mountains, seventy percent seas and oceans, fertile lands, immense forests, rivers and lakes, sea shores and deserts, this is where we humans have the privilege to live, the latest, most advanced newcomers in evolution. What an immense, incredible responsibility we have to be a right, positive element in the further evolution of that planet. That is the big question before us in the new century and millennium.
